INSTALLATION

MOUNTING

MTL-Relcom Redundant Fieldbus Power Systems (FPS) are designed for

mounting on 35mm DIN rail. For maximum cooling, the DIN rail should

be mounted horizontally so that air can flow vertically between the

power modules.

INPUT POWER SUPPLY CONNECTIONS

For redundant operation, two separate DC power supplies should be

connected to each FPS. Four pairs of terminals are provided on each

FPS for this purpose; two pairs for each input power supply. The extra

pair of terminals for each input power supply are intended to be used

for connection to another FPS installed immediately adjacent to the first.

Prefabricated jumper assemblies are included with each FPS-I for this

purpose. When multiple Fieldbus Power Systems are wired together

using jumper assemblies, redundant connections should be made to the

two input power supplies using the terminal pairs located at each end of

the row of systems.
