Note:
1.
The NAC circuit shown in the diagram is the active state at terminal 1 and 2 of ABHW-4BZ.
2.
ABHW-4BZ terminals 5-6 are polarity insensitive. Line 1 and Line 2 can be either line of
device loop.
3.
The wiring at NAC of PAD-3/PAD-4/PAD-5 shown in the diagram for ABHW-4BZ is Style Z
(Class A)(No EOL needed). If Style Y (Class B) wiring used at NAC output, EOL (24K, 0.5W
resistor) must be used.
4.
For the max load current and max cable resistance, refer to the specifications of PAD-
3/PAD-4/PAD-5, P/N: 315-099082/315-050217/A6V101030358.
