3 Safety Instructions
Finger guards t over the soft starter power terminals to
increase IP rating and prevent accidental contact with live
terminals.
WARNING
ELECTRICAL SHOCK HAZARD
VLT® Soft Starters contain dangerous voltages when
connected to mains voltage.
Models MCD5-0360C ~ MCD5-1600C: The bus bar and heat
sink are live while the unit operates (starts, runs, or stops). If
the soft starter is installed without a main contactor, the bus
bar and heat sink are live whenever mains voltage is
connected. This is also the case when the soft starter is
ready or tripped.
Improper installation of the motor or the soft starter, and
installing or servicing with power connected, can cause
death, serious injury, or equipment failure.
To avoid death, serious injury, or equipment failure:
•
Only use qualied electricians for carrying out the
electrical installation.
•
Disconnect the soft starter from all power sources
before installation or service.
•
Fit
nger
guards to all terminals, even if no cable is
connected.
•
Treat the bus bar and heat sink as live whenever
the unit has mains voltage connected. Also take
this precaution when the soft starter is tripped or
waiting for a command.
•
Follow the guidelines in these instructions and local
electrical safety codes.

MCD 500 G3C enclosure size models only: Fit the
nger guard base chassis to the MCD 500 enclosure
rst before installing rubber nger guards.
2. Feed each power cable through the narrow end of
each nger guard. Connect the cables to the
appropriate terminals on the soft starter.
3. If the cables do not t through the nger guards,
shorten the nger guards at the narrow end to make
a bigger opening.
4. Screw the retaining bracket to the soft starter.

Installation
1. Fasten the nger guard base chassis to the main
enclosure of the soft starter using the screws
provided.
2. Drill power cable access holes into the gland plate
using the pilot holes provided. To prevent excessive
heating of the gland plate due to large eddy
currents, cut horizontal slits between the power cable
holes drilled into the gland plate.
3. Fit the gland plate to the nger guard base chassis
using the screws provided.
4. Run the power cables through the holes in the gland
plate and connect to the appropriate bus bar
terminals of the soft starter. To prevent fraying of
cables against the gland plate, t cable bushes or
glands (not supplied) appropriate for the size of
cable used.
