							CEU/Power Supply Site Requirements
Choose a central site for the MDF plywood backboard, with-
in 7’ of a dedicated AC outlet and 25’ of earth ground.
Allow space for multiple CEU’s and power supplies. CEU’s
must be located within 3’ of each other. Power supplies
must be located within  6’ of  the CEU and within 6’ of a
dedicated AC outlet. See Figure 1.
Allow space for telco and station connectors, all ancillary
equipment (ie; BGM/MOH source, voice mail, external pag-
ing equipment), and expansion. Refer to Nitsuko’s Standard
Practices Manual (P/N N2710STD01) for general environ-
ment and site specifications.
Mounting the CEU
1. Locate CEU mounting screws. Drill holes (2) in
backboard using a 1/8” drill bit. Refer to mounting
dimensions in Figure 2 (or use template, if installed). 
2. Install CEU mounting screws (2) in holes. See Figure 2.
Use screw gauges to set proper screw depth.
(Screws & gauges are in plastic packet). 
3. Hang CEU on mounting screws.
4. Drill lower CEU screw hole using a 1/8” drill bit.
See Figure 2. Install and tighten screw.
5. Ground each CEU using #12 AWG (or larger) 
ground wire to earth ground.

							Mounting the Power Supply
1. Use power supply as template to locate mounting
screw holes.
2. Drill holes (2) in backboard using a 1/8” drill bit.
3. Locate power supply over holes.
4. Install screws (2-not provided).
Connecting the Power Supply to the CEU
1. Loop the power supply CEU power cord 3 times
through a ferrite bead (supplied in box).
2. Plug in the power supply CEU power cord into the 
MAIN POWERconnector on the CEU. See Figure 3.
Do not plug the power supply into an AC outlet.
Power Strip/Surge Protector Connections
1. Plug the power supply cord into a power strip.
2. Plug the power strip into an AC surge protector.
3. Plug the surge protector into a dedicated AC outlet.
Powering Up
1. Turn the power switch on the power strip ON.
Refer to Power Up Procedure below (see Figure 4) for
proper sequence when not using a power strip.

							Installing CO and Station Modules
Power down to install or remove any module. 
To install CO and Station Modules:
1.Line up the screw hole in the new module (i.e., the one you
are installing) with the pilot hole in the CEU base or existing
module. See Figure 5.
2.Place new module on CEU or existing module. If placing new
module on existing module, be sure to line up the ground lugs.
3.When placing new module on CEU, insert short screw through
new module and into CEU base. Tighten screw.
ORWhen placing new module on existing module, insert long
screw through new module and into CEU base. Tighten screw.
4.Insert the ribbon cable into the desired connector on the CEU:
(a) inside modules ribbon cable plugs into the outside
connector (b) outside modules ribbon cable plugs into the
inside connector.

							Installing AUX, SAUX, and XAUX Modules
A minimum of 7 clearance is required on the right side of a
CEU to install an AUX/SAUX/XAUX.  Power down to install or
remove an AUX/SAUX/XAUX module or an 8-pin line cord.
Note:Initialization is not required to add an AUX to a system
running on CEU base software. The numbering plan, however,
changes automatically for lines, extensions, and ring groups.
To install an AUX, SAUX, and XAUX Module:
1.Remove cover plate.
2.Close CEU ejector tabs and insert the AUX into the CEU
upper and lower rails.
Push the module in until it clears
the CEU ejector tabs. See Figure 8.
3.Open ejector tabs. Locate ribbon cable over connector.
4.Push in the module until it seats firmly into the CEU.
5.Push ribbon cable connector until firmly seated. The CEU 
ejector tabs close. Tighten module screws (2).
To install AUX, SAUX, and XAUX line cords:
1.Install line cords. Two CEUs: AUX-SAUX 6 line cord; three
CEUs: AUX-XAUX 3 line cord & XAUX-SAUX 6 line
cord. See Figure 10.
Note:AUX terminal program passwords: ONYXVSK, if AUX
is installed in a working system, but not initialized; DS01H, if
initialized with AUX installed.

							CO Line Installation
A modular line cord is required to connect Telcos RJ11C CO line
interface to a 4CO or 4CO\CND module. See Figure 7.
To connect a CO line to a 4CO or 4CO\CND module:
1.Plug one end of a modular line cord into a Telco RJ11C jack.
2.Insert the line cords other end into the desired modular connector
on a 4CO or 4CO\CND module.
Installing Stations
Station connection for each extension requires two-pair twisted
station cable and a 4-conductor modular jack. See Figure 11.
Install a Dual ASI (any CEU) and DSS console (Main CEU only) to
an even-numbered port (except port 00). Leave the next-highest
adjacent odd-numbered port unterminated. See Figure 12. 
Note:Single and Dual ASIs cannot be installed in ports 68-71.
To install a multibutton telephone, single port ASI, Electronic
Single Line telephone, or DSS console:
1.Install 625 modular jack within 6 feet of each extension.
2.Punch down 2-pair twisted station cable to desired extension
on cross-connect block. See Figure 13 for cutdown.
3.Terminate the other end of the station cable at each modular jack.
4.Plug the extensions line cord into the modular jack.

							Installing a Music Source - Background Music or Music on Hold
A music source (radio, cassette, CD) connected to MOH terminals on
the Main CEU provides input for Background Music (BGM), or
Music on Hold (MOH), or both. MOH can be provided for CO calls only
or for CO and ICM calls. 
BGM and/or MOH for ICM calls disables the Main CEUs 4th CO line
circuit. MOH for CO calls only does not disable a line circuit. Each
Expansion CEU can have its own MOH source or use the Main CEUs.
To connect a music source:
1.Install the music source per the manufacturers instructions.
Caution:The music source output must not exceed the systems
music source input specifications. Some music sources may require
the installation of a matching transformer.
2.Connect the music source to the Main CEUs MOHterminals using
station or audio cable. Note:Bridge the music source output to an
Expansion CEUs MOH terminals, if required.
3.Program BGM and MOH per the Terminal Programming Manual
(E2 + QM) or Administrators Guide (Programs 7 and 10).
4.Install RFI suppressor beads. (Refer to RFI bead installation)
5.Power up the music source.  Activate BGM/MOH.  Adjust the music
source for a distortion-free signal.

							4. BGM/MOH, PAGING, AND LOUD BELL
AUX MOH PA GND12121212
Installing External Paging or an External Relay Device (Loud Bell)
The PA terminals on the Main and Expansion #1 CEUs provide talk
paths for external paging systems. The Main CEU PA terminals are for
external zone 1. The Expansion #1 CEU PA terminals are for external
zone 2. A paging system receives internal or external pages, or Night
Audible ringing, or both. Each page system disables a line circuit: Main
CEU - line 4; Expansion CEU #1 - line 12. The AUX terminals on the
Main and Expansion #1 CEUs provide a dry contact ring relay. The relay
can be used for a loud bell, a door striker, etc.
To connect an external paging system or relay sensor:
1.Install the paging system/relay sensor per manufacturers
instructions. Caution:The paging system must not exceed the
systems paging input specifications. Some paging systems may
require the installation of a matching transformer. See Figure 15.
2.Connect the paging system to the PAterminals or the relay sensor to
the AUX terminals using station or audio cable.
3.Program External Paging/Relay Owner per the Terminal
Programming Manual (E2 + QM) or Administrators Guide
(Programs 7 + 10).
4.Install RFI suppressor beads. (Refer to RFI bead installation).
5.Power up the paging system. Make page. Adjust the paging
system for a distortion-free signal. Check relay sensor by dialing the
relay owner extension number.

							Installing a Programming Terminal, SMDR printer, PC, or Modem
The AUX Module DCE 9-pin male RS-232 serial port interfaces a program-
ming terminal, SMDR printer, PC (DTE), or a modem (DCE). A DB9-DB25 
adaptor is required. DTE connection requires a straight-thru RS-232 cable. 
DCE connection requires a DCE-DCE adaptor and a straight-thru RS-232 
cable OR a null modem cable.
Note:A null modem or RS-232 cable requires DB25 connectors. Gender of
the DB25 connectors depend on the adaptor and the terminal, SMDR 
printer, or PCs serial port.
To connect a DTE programming terminal, SMDR printer, or PC:
1.Plug a DB9-DB25 adaptor into the AUX port. The DB9 must be female.
2.Connect one end of the RS-232 cable to the adaptors DB25 connector.
3.Connect the other end of the RS-232 cable to the serial port on the
programming terminal, SMDR printer, or PC. See Figure 16.
Note: When connecting a laptop PC equipped with 9-pin serial port, use
a straight-thru 9-pin RS-232 cable.
