The following versions of the RPS1U rack power supply are available:
• An RPS1U for use with an AC-mains supply.
• An RPS1U for use with a DC-mains supply.
The different versions are distinguished by their ordering number (refer to the VM600 slimline
rack (ABE056) data sheet).
The RPS1U rack power supply must be with an appropriate connection panel at the rear of
the VM600 rack in order to allow the connection of external AC-mains or DC-mains power to
the rack. See also 8.3 Rack safety requirements.

The power supply check relay provides an indication that the +5 V, +12 V and î›­12 V supplies
are being correctly generated and delivered by the RPS1U rack power supply to the VM600
slimline rack (ABE056) backplane. The connector for the power supply check relay is
available at the rear of the rack.
NOTE: Refer to the VM600 slimline rack (ABE056) datasheet for further information on the
power supply check relay.
As shown in Figure 2-33, the connector for the power supply check relay has three pins that
provide access to the relay contacts, defined from left to right as COM, NO and NC.
Apart from the power supply check relay connector, the other components shown in
Figure 2-33 are mounted on the VM600 rack (ABE056) backplane.
