Mounting Module to HMC7000:
The HMC7 I/O module must be mounted onto the back of a
HMC7000 Series unit using one of the HMC expansion ports.
When locating equipment behind the HMC7000 ensure that AC
power wiring, PLC output modules, contactors, starters, relay
and any other source of electrical interference are located
away from the HMC7000. Make sure that variable speed drives
and switching power supplies are located away from the unit.
Step 1
Step 2
Step 3
Step 1: Pull the two white lock connectors out from the center
of the module.
Step 2: Place the module onto the HMC7000 expansion port so
that the I/O module interconnect plug can attach to the
HMC7000 socket.
Note: remove the protective tab on the
HMC7000 expansion port to expose the socket.
Step 3: Push down the lock connectors to safely secure the I/O
Expansion module.
Wiring I/O Expansion Modules:
The HMC7 I/O module has green block terminals that are used
to wire the module to the digital input devices (i.e. switches,
contacts, etc). The block terminals can be physically removed
from the module to facilitate connection (18-gauge wire
recommended).
Note: A 3/32” �lat blade screwdriver should be
used to tighten the screws of the terminal block.
