Modular ICS Companion Installer Guide P0992639 01
Connecting expansion modules
In order to keep the default port and extension numbering, 
connect Trunk Modules to the Expansion Cartridge beginning 
at the top and working down; connect Station Modules to the 
Expansion Cartridge beginning at the bottom and working up.
Installing Remote Power Interconnect (RPI) units
Installation planning is required for base 
stations.
Before connecting any Station Modules required 
for base stations, please see 
Configuring 
expansion modules
 on page 8  for more 
information on the installation rules involved.
The RPI unit should have the DC backup power 
supplied by a UL listed UPS.
The UPS should have an output voltage rating of 44 to 
50 V DC, with a maximum fault current limit of 6 A to 
protect the RPI output wiring. Otherwise, it may be 
necessary to use class 1 wiring.
The RPI units must always be installed inside a 
building.
The AC outlet powering the RPI should be installed near 
the equipment and should be easily accessible. 
The length of the RPI cord, from the outside surface of 
the unit to the plug, should be a minimum of 1.3  m (4 1/
2 ft.) and a maximum of 4.6  m (15 ft.).

RPI unit 
There are two versions of the RPI unit: the RPI-8 BIX UL, 
which supports up to eight base stations; and the RPI-16 BIX 
UL, which supports up to 16 base stations. Each RPI has a 
connection board and either one (RPI-8 BIX UL) or two (RPI-
16 BIX UL) power supply units (PSUs). The maximum input 
power consumption of an RPI is 240 W. If a UPS 48 V DC 
backup source is used, the maximum input power requirement 
of the RPI is 140 W.
You can upgrade an RPI-8 BIX UL to an RPI-16 BIX UL by 
installing a second PSU to the RPI-8 BIX UL. Refer to 
Upgrading an RPI-8 to an RPI-16 on page 119.
If RPIs are distributed throughout the site, the number and type 
of RPIs depend on the placement and powering plan of the 
base stations.
To determine how many base stations and how many PSUs 
you need for the number of base stations, use the following 
table:

RPI Requirements
Mounting the RPI unit
1. Position the screw holes for the RPI using the dimensions 
shown in the following figure.
RPI mounting holes
To provide adequate ventilation and to prevent 
overheating, leave a clearance of at least 125 mm (5 in.) 
around the RPI.
If you are mounting two RPIs, one above the other, leave 
a clearance of at least 300mm (12  in.) between them to 
provide adequate ventilation and to prevent overheating.

P0992639 01 Modular ICS Companion Installer Guide
Mount RPIs at least 300 mm (12 in.) from the ceiling.
2. Insert wall plugs in the holes.
3. Partially screw in two #10 50-mm (2-in.) screws for the 
keyholes.
4. Open the hinged cover with a screwdriver by pushing in 
and then down to release the catch on the right side. You 
can remove the cover by lifting it off its hinges.
Opening the RPI cover
5. Hang the RPI on the two keyhole screws and tighten them.
6. Install the remaining two screws. 
7. Feed the power cord through the bottom of the RPI and 
route it through the clip and around the strain relief support 
as shown in the following figure. 
8. Route the power cord to the input power socket just to the 
left of PSU 1. Connect the plug to the socket.
Note:  Distinctive labeling of RPIs may help to diagnose any 
future problems.

RPI components 
The RPI-8, which has only one power supply unit, has 
grounding straps and plates fitted so it can be upgraded to an 
RPI-16 (see illustration RPI components).
Wiring the RPI
The maximum two-way DC loop resistance for power pairs, 
including interconnections for each base station, is 75 ohms. 
You need one or two power pairs between the RPI and the base 
station, depending on the wire size of the power pairs and the 
distance between the base station and the RPI.
Unplug the RPI power cord.
Do not apply power to the RPI until its installation and 
wiring are complete. 
Do not run unprotected power cables outdoors.

Maximum power cabling distance (approximate)
Depending on the size of cable you are using, you should 
remember the maximum cabling distances allowed between 
the RPI and the base station.
RPI Connector Overview
The following illustration shows where the input and output 
connectors are located on the RPI connector board.

Output connections
Feed the output pairs in through the bottom of the RPI and 
route the pairs to the output connectors as shown in the 
following illustration. If only one pair is used for powering a 
base station, connect the power pair to -PWR(1) and 
+PWR(1). If two pairs are used to power a base station, 
connect one pair to -PWR(1) and +PWR(1), and the second 
pair to -PWR(2) and +PWR(2). 
Output connector pinout
Input connections
Feed the TCM input pairs from the ICS distribution frame 
through the top of the RPI and route the pairs to the input 
connectors (IBIX1 to IBIX4) as shown in the following 
illustration. There may be fewer than 16 input pairs in any 
given RPI installation.
Ensure both pairs have the same polarity.
Connecting two power pairs with opposing polarities 
may damage the base station and RPI.
