Wall Mounting
It is also possible to mount the MPC device to a wall using the
optional 50008533-001/U Wall Hanging Accessories Kit. The
following sequence describes how the device should be
prepared prior to mounting it on a wall (see Fig 4).
Place the MPC with the topside
down on the desk.
Remove the four feet from the bottom of
the MPC by pushing horizontally away from
the housing with a flat screwdriver.
Push the four inserts (included in optional
50008533-001/U Wall Hanging Accessories
Kit) fully and horizontally into the housing.
Adjust the four retaining clips (included in
optional 50008533-001/U Wall Hanging
Accessories Kit) on top of the inserts.
Fasten the retaining clips with the
included four screws.
Use the housing with the clips to mark the
positions of the four mounting holes on the
wall surface. Drill 1/8 in. (3 mm) holes for
the mounting screws (not included -
supplied locally) and fix the MPC device.

CONNECTIONS
This section describes how to connect power and the field bus
to the MPC device. A supply pack with installation material
containing the required connectors for power and the field bus
is shipped with the device.
Power Connection
The MPC device requires a UL 864 listed external power
supply with the following specifications: 24 VAC, 50 to 60 Hz,
or 24 VDC.
Typical power supplies include:
CUI Model EMSA240075-P5P-SZ 120/240 Vac, 50/60 Hz
input, 24 Vdc, 0.75 A output, Class 2.
50/60 Hz input, 24 Vdc, 0.75 A output, Class 2, or CUI Model
SMI18-24-V-P5, 120/ 240 Vac, 50/60 Hz input, 24 Vdc, 0.8 A
output, Class 2 (included).
For the power connection, the 3-pole Phoenix connector is
required (included).
Wire the power cable as follows:
Preparation
If the power adapter cable contains a barrel connector, then
cut off the original connector at the end of the cable. Strip the
two cable ends to expose 3/8" (10 mm) conductor length and
twist the cable strands. If the power adapter contains screw
terminals, then wire a cable to the 24 V and GND terminals on
the power supply. If the power adapter cable contains ferrules
installed on them, then the ferrule pins can be terminated
directly into the device power connector as described below.
Termination
1. Insert the two cable ends into the left two openings of
the 3-pole Phoenix connectors that are marked for
power.
2. Fasten them with a small screwdriver.
3. Connect a chassis ground
M22588A
this connector as marked.
NOTE: The polarity (+/-) of the 3-pole Phoenix power
connector for DC power supplies is don't care.
Field Bus Connection (Ch1/Ch2)
The 2-pole Phoenix connectors (included) are required for
connecting the field bus. Field bus connection can be
configured only as class B/style 4. All field wiring is
supervised.
Level Converter Connections and
Powering
For connecting RS485 level converters to MPC devices,
observe the polarity of the converter devices to connect the
(+) and (-) wires to like terminals. Follow the installation
instructions accompanying the level converter devices for
connections and powering of those devices.
For connecting the RS232 cables between level converters
and to power them, follow the instructions accompanying each
device when connecting to it.
