Installation
Installation checklist
When installing a Norstar system with Companion 
components, follow this installation checklist:
åcomplete the wiring
åinstall the Remote Power Interconnect units*
åinstall the base stations*
åinstall the external antennas and lightning surge arrestors*
åmount the Integrated Communication System (ICS) and 
expansion modules (as required)
åinstall the NVRAM Cartridge (if required)
åinstall the ROM Software Cartridge...

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,...

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...

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...

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.

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...

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).
