HGM-MZ to N2 Communications Adapter
2
Rev 1 (P/N 3015-5514)
Step
Description
1.
The adapter board mounts on the rear of the HGM-MZ enclosure door. Position the adapter board
over the five standoffs on the door and install with 6-32 fasteners through the board and into the
standoffs.
2.
Connect power wiring from the HGM-MZ’s 120/240V Universal Power Supply terminal block to the
adapter board’s POWER terminal block. Use UL approved wire. Wire polarity does not matter.
3.
If an MZ-RD remote display is NOT used with the adapter, refer to Figure 1 for wiring details. In this
case, all wiring between the HGM-MZ and the only external cable is the N2 communications cable.
4.
If an MZ-RD remote display IS to be used with the adapter, refer to Figure 2 for wiring details. Note
that when the MZ-RD is used, TWO RS-485 cables must be run between the HGM-MZ and MZ-RD,
so plan accordingly.
5.
In either case, be sure to set the HGM-MZ’s internal “terminator” slide switch next to the RS-485
terminal block to the “In” position.
