4.3 Anchoring wall mounted HMI (Entellisys only)
General requirements
The Entellisys switchgear can be optionally
provided with a wall mounted HMI (Human Machine
Interface) unit, Fig. 4.36. Before installation of
the HMI unit, ensure that the surface to which the
enclosure will be mounted is capable of supporting
85 pounds.
Installation
The recommended procedure for installation of
the Entellisys wall mounted HMI unit is as follows:
1. Add two conduit connection holes in either the
top or bottom surface of the HMI unit enclosure.
Do not position the holes less than 1-1/2 inches
from the edges of the enclosure, Fig. 4.37.
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 to 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. Installing the sealing washers inside the
enclosure with the tapered cone against the
enclosure and then add the flat washers as
shown in Fig. 4.38 and 4.39.
4. Attach suitable conduit fittings to the holes
from step 1. Run the conduit to the enclosure
as necessary.

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