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 FC2025/FC2050/FV2025/FV2050 and FC922/FC924/FV922/FV924
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 (2.4K, 0.5W resistor) must be used.
4.
For the max load current and max cable resistance, refer to the specifications of FC2025/FC2050
/FV2025/FV2050 and FC922/FC924/FV922/FV924.
