POWER INPUTS
The power supply must be surge protected, otherwise
external surge protection is required at the input to the supply .
IEC Class I regulated power supply
„
Min . Output: 12 VDC @ 100mA, 24 VDC @ 50mA
Connector / Wiring Requirements
„
Wire Range: AWG #24 - 14 SOL / STR (1 wire only)
Wire strip length: 9 .0mm (min) / 10 .0mm (max)
AVT CONNECTION
Provides power and communications to the AVT isolation module . The connection features a pluggable screw terminal connector .
Only install the network module in the same electrical enclosure as the VeriSafe 2 .0 AVT isolation module .
Recommended Wiring
VOLTAGE PRESENCE OUTPUTS
Reflects status of Voltage presence LEDs on the AVT indicator module . These outputs are updated every 2 seconds based on the state
reported from the AVT isolation module . These outputs are not an indication of absence of voltage .

DC Input
When using the network module with the 2 .0 AVT isolation module, the
network module "AVT Connection" supplies power from the network module
to the isolation module . Therefore DO NOT apply an external power source
to the 2 .0 AVT isolation module when used with the network module .
