BEFORE MOUNTING THE MCP IN AN ELECTRICAL
SYSTEM, MAKE SURE THE MCP IS SWITCHED TO
THE OFF POSITION AND THAT THERE IS NO VOLT-
AGE PRESENT WHERE WORK IS TO BE PER-
FORMED. THE VOLTAGES IN ENERGIZED EQUIP-
MENT CAN CAUSE DEATH OR SEVERE PERSONAL
INJURY.

NOTICE
Depending on the equipment configuration, the
MCP can be mounted using different styles of hard-
ware. The following steps describe how to mount
the MCP using standard hardware. When special
hardware is needed (for example, with handle mech-
anisms), the instruction leaflet describing the acces-
sory also describes the special mounting arrange-
ments.
a. For individual mounting panels, make sure that
mounting panel is predrilled using drilling plan
(Figure 2-1).
b. If MCP includes factory installed internal acces-
sories, make sure accessory wiring can be
reached when the MCP is mounted.
c. Position MCP on mounting surface.
d. Install mounting screws, washers, and nuts.
Tighten screws firmly, but do not exceed 28
pound-inches (3.16 N.m.).

An adapter kit (S#1275C79G02) suitable for use with
standard 35 millimeter DIN rail (such as 35 mm x 7.5 or
35 mm x 15 per DIN EN50022), should be preassem-
bled to the rear of the circuit breaker (Figure 2-2).

WHEN ALUMINUM CONDUCTORS ARE USED, THE
APPLICATION OF A SUITABLE JOINT COMPOUND
IS RECOMMENDED TO REDUCE THE POSSIBILITY
OF TERMINAL OVERHEATING. TERMINAL OVER-
HEATING CAN CAUSE DAMAGE TO THE MCP.
2-3. After mounting the MCP, line and load cables and
accessory leads should be connected. (See accessory
schematic diagram on side of MCP.)
