2.1.3 Redundant DC Power

The WCM is optionally available with a dual input, 1+1 redundant DC (-48V) power supply

The redundant DC power supply operates of two
independent -48V supplies, which feed a pair of 1+1
redundant DC power modules inside the unit. This
option therefore provides resiliency in the event of both
external power feed failure, or of an individual power
module failure.

The internal DC power modules are polarity protected,
and internally fused.

Metrodata recommend the use of fork terminals, (not
supplied) for connection of power, as shown:

However, if necessary, the stripped and twisted ends
of the power wires may be inserted into the screw
terminals, as shown. Ensure no stray strands of bare
wire can touch either the unit casing, or the other
supply terminal.

The unit must be earthed using the external M4 Stud
and securing screws. EMC performance may be
degraded if a proper earth connection is not provided.
