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 a conduit connection hole 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. 4-28 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. 4-26 and 4-27.
4. Attach a suitable conduit fitting to the hole 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-.
