Installation
WARNING: Do not remove or install an Isolated Power Module (IPM) unless the area is known
to be non-hazardous.
Refer to the Control drawing included in this document for a typical installation. The drawing is intended
to address the safety aspects of Class I, Division 2 areas. Actual segment connections may vary depending
on factors such as the required number of Fieldbus segments.
Mounting
Relcom redundant Fieldbus Power Systems (FPS) are designed for mounting on 35mm DIN rail inside
of an enclosure with a minimum rating of IP 54. Use of DIN rail end stops is recommended.
DIN rail mounting may be horizontal or vertical.
Note: Operating temperature range is -40°C to 50°C if installed on vertical DIN rail.
Once all wiring connections have been made, the retaining screws on each pluggable cable connector
should be securely fastened.
Input Power Supply Connections
For redundant operation, two separate input 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. A prefabricated jumper assembly is included
with each FPS for this purpose.
In most installations the distance from a bulk power
supply to the FPS is less than 30m. If the distance
from the bulk power supply to the FPS is in excess
of 30m, then a suitable Surge Protection Device
should be used.
When multiple Fieldbus Power Systems are wired
together using jumper assemblies, redundant con-
nections should be made to the two input power
supplies using the terminal pairs located at each
end of the row of systems. An example of multiple
systems wired this way is shown in Figure 2.
