Control Panel Components

Manual Motor Protector (MMP)
The manual motor protector (MMP) provides coordinated
branch circuit, short circuit protection, a disconnecting means,
a motor controller, and coordinated motor overload protection .
The MMP trip points are factory set and locked, see
14 . Do not change unless the motor ampacity changes or the
MMP is replaced with a new device with incorrect set point
adjustment . Any other non-authorized trip point or set point
adjustment voids all or portions of the unit's warranty . Setpoint
values are published on the schematic, near the MMP for each
MMP . The MMP should be set to the value published on the
schematic and locked by the factory .
To reset a tripped MMP, clear the trip by rotating the knob
counterclockwise to the OFF position; then rotate the knob
clockwise to the ON position . See "2" in
If an overload or a fault current interruption occurs, check
circuits to determine the cause of the interruption . If a fault
condition exits, examine the controller . If damaged,replace it
to reduce the risk of fire or electrical shock.

Circuit Breaker
Circuit breakers are installed upstream of all VFDs to provide
short circuit protection
To reset a tripped circuit breaker: Clear the trip by rotating the
lever down to the OFF position . Then rotate lever up to the ON
position .
Other MMP features:
• Three-position rotary operator: OFF-TRIP-ON . See "2" in
Figure 15 .
• Lockout—tagoutable rotary operator: turn the rotary
operator to OFF, slide out the extension arm, and insert a
lockout pin .
• Ambient compensated –20°F to +60°F
• Single-phase sensitivity: if one phase exceeds set point,
all three phases open .
• Trip test: insert a 9/64" screw driver in the slot to simulate
a trip . See "3" in
