1 x TDS-AR supports:
20 x TDS140-2S
or 10 x TDS 180-4S
or 5 x TDS 1160-8S
or relative combinations.
It is recommended that the TDS-AR unit be
powered from the same power circuit that
feeds to the Surge Suppressor being
monitored, however it can be powered from
other circuits. This allows for example, one
TDS-AR unit to be connected to separate
Surge Suppressors that are protecting a three
phase circuit.
To satisfy Australian wiring regulations the
phase supply to the TDS-AR needs to be
protected by an overcurrent fuse/circuit
breaker. The overcurrent protection should be
selected according to the wiring size
connecting to the TDS-AR Phase and Neutral
terminals. For reference a table of values is
given on page 24.
Note. Depending upon the usage of the TDS-
AR output contacts, failure of power to the
TDS-AR may be interpreted as a failure of one
or more Surge Suppressors. Visual inspection
of all units Status displays would determine
this.
