Modular ICS Companion Installer Guide P0992639 01
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.
