2. Installing RPCM
2.2. Mounting RPCM DC ATS 76A, RPCM DC 232A
2.2.1. Description
This chapter section contains instructions for installing the Resilient Power Control Module
(RPCM) and is intended for personnel with the appropriate qualifications.
Before you begin, read this guide to help you complete the installation process. If necessary, con-
tact RCNTEC support for assistance.
Adhere strictly to the safety precautions listed below.
2.2.2. Installation and Operation Requirements
Power and ground requirements for RPCM DC ATS 76A:
voltage -42 - -58 VDC;
grounding;
easy accessibility of switches or circuit breakers of both inputs for disconnection in case
of danger.
Power and ground requirements for RPCM DC 232A:
voltage -42 - -58 VDC;
grounding;
easy accessibility of switches or circuit breakers for disconnection in case of danger.
Note.
In order to protect outlets from short circuits, short circuit protection selectivity has to be
ensured in the electrical design.
For RPCM DC ATS 76A, RPCM DC 232A
— short circuit protec-
tion trips at ~87.5A current on the outlet. Short circuit tripping time – around 100 microseconds.
In order to isolate short circuit on individual outlets you should choose circuit breakers on input
that have tripping delay 2 ms or longer.
2.2.3. Preparatory steps
CAUTION!
To reduce the risk of fire, electric shock, or damage to power sources, observe the fol-
lowing rules:
Before connection the input power, make sure that all Switches or Circuit Breakers are in the
OFF position;
Make sure that the equipment connected to the module outputs are configured and suitable
for operation at the same voltage levels as RPCM module — 48 VDC. Failure to ensure cor-
rect voltage ranges can lead to serious damage to the equipment.
