Wall Mounted HMI (Entellisys AR Only)
General
The Entellisys switchgear can be optionally provided with a
wall mounted HMI (Human Machine Interface) unit (Figure
4.26). 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 (Figure 4.27).
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 Figure 4.28 and Figure 4.29.
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
cable to the converter terminals labeled RX+ and RX-.
