POWER INPUTS
DC Input
Network Connection (PoE)
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)
10/100 PoE
IEEE 802 .3af Type 1 Class III PoE topology .
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
Connector Specifications
Connector / Wiring Requirements;
Wire Range: (1 wire): AWG #24 - 12 [2 .5mm2] SOL / STR
(2 wire): AWG #18 [1 .0mm2] SOL
AWG #18 [1 .5mm2] STR
Wire strip length: 7 .0mm (min) / 8 .0mm (max)
Screw Drive Size: M3x0 .5
Screw Torque Required: 5 .0 in-lb [0 .57 N-m] +/- 10%
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 .
Output Specification

Module
The termination resistor
switch below the AVT
connection ports on the
network module and AVT
isolation module shall be
positioned to the right
(factory default) when
facing the port
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 .
