7.2.2 Input Power Fuse Protection
The RCM includes power input fuse protection and reverse wiring protection. The fuse is not
replaceable. All other power supply voltages and conditioning circuits are distributed on the SAM and
monitoring modules.
7.2.3 Power Status (LEDs)
The RCM has two LEDs that indicate power status. Refer to section 23.3.1 for information on
troubleshooting if the LEDs are not as shown.
Power 1 is between +18 and +36 Vdc.
P2
Power 2 is between +18 and +36 Vdc.
Table 7-1) RCM LED States
You can monitor the status of the power supplies through Modbus.
7.2.4 Selecting an External Power Supply
The amount of power required varies greatly depending on the number (and loading) of the
monitoring modules. The power supply wattages (from the MPS datasheet) shown here, will handle
fully filled and fully loaded racks for the size given.
• 480 W supply for a 16P rack
• 180 W supply for an 8P rack
• 90 W supply for a 4P rack
See the RCM data sheet (S1078950) for more information on the external power supplies provided by
B&K Vibro.
The external power supplies are powered from hazardous high voltages. Only qualified
personnel should make connections to the power supply.
