Installation Instructions
4.2 IP20 Protection for MCD5-0245B ~
MCD5-0961B
MCD 500 (enclosure sizes G3B and G4B) models use rubber
finger guards. Rubber finger guards provide IP20 protection
when used with cable of diameter 22 mm or greater.
Installation
1. MCD5-0245B ~ MCD5-0396B: Screw the finger guard
plate to the base of the soft starter.
MCD5-0469B ~ MCD5-0961B: Screw the finger guard
bracket to the enclosure of the soft starter.
2. Fit 1 polycarbonate retaining bracket over each finger
guard.
3. Feed each power cable through the narrow end of
each finger guard. Connect the cables to the
appropriate terminals on the soft starter.
4. If the cables do not fit through the finger guards,
shorten the finger guards at the narrow end to make
a bigger opening.
5. Screw each retaining bracket to the finger guard
plate/bracket.
6. MCD-50469B ~ MCD5-0961B: Fit the finger guard
cover over the bracket to complete the arrangement.
7. Repeat steps 1–6 for the other set of terminals.

Fasten the finger guard base chassis to the main
enclosure of the soft starter using the screws
provided.
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.
Fit the gland plate to the finger guard base chassis
using the screws provided.
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, fit cable bushes or
glands (not supplied) appropriate for the size of
cable used.
Fit the finger guard cover over the finger guard base
chassis to complete the arrangement.
Repeat steps 1–5 for the other set of terminals.
