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...

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.

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.

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...

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...

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:...

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

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,...
