Note:
1. The NAC circuit shown in the diagram is the active state at terminal 1 and 2 of ABHW-4S.
2. ABHW-4S 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-4S 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.
