4-3 Installation of Wall-Mount HMI
General Requirements
Before installation, ensure the surface to which the enclosure will be
mounted is capable of safely supporting 85 lb.

Enclosure Installation
The recommended procedure for installation of a wall-mount HMI is
as follows:
1. Add two conduit connection holes in either the top or
bottom wall of the enclosure. Do not position the hole less
than 1.5 inches from the edges of the enclosure. See Fig.
4-32 for area suitable for conduit hole.
2. Four mounting holes are provided in the back of the
enclosure. Drill an identically spaced pattern of holes in the
surface to which the enclosure will be mounted according
to the drawing supplied with the enclosure.
3. Attach the enclosure to the wall or other structure using
3/8 inch bolts, flat washers, and, if the bolts are not self-
threading, lock washers and nuts. To ensure proper
sealing and enclosure protection rating, use the provided
sealing washers. Install the sealing washers inside the
enclosure with the tapered cone against the enclosure
and then add the flat washers as shown in Figs. 4-30 and
4-31.
4. Attach suitable conduit fittings to the holes from Step 1.
Run conduit to the enclosure as necessary.

Device Wiring
The recommended procedure for connecting the HMI power and
communication cables is as follows:
1. Connect 120VAC line, neutral, and ground wires to
terminal block as shown in the wiring diagram included
with the assembly.
2. Connect incoming Ethernet cable to the port on the side of
the HMI. Secure the wires to HMI and enclosure with cable
ties.
3. If the enclosure is equipped with a power supply and
RS232/RS485 converter, connect the incoming RS485
cable to converter terminals RX+ and RX-.
