it is however highly recommended to fasten
these modules to the mounting base also by
two screws through the lower mounting holes.
For installation of the cold plate drive modules
(ACSM1-04Cx-xxxx-x), follow the instructions
in the ACSM1-04 Drive Modules (0.75 to 45
kW) Hardware Manual.

*Note: For motor cabling, use a separate
ground cable if the conductivity of the motor
cable shield is less than 50% of that of a phase
conductor and the cable has no symmetrical
ground conductors.
Power cabling procedure
Cabling examples are presented on page 5.
Tightening torques are presented on page

• ACSM1-04xx-024A...090A-4 only: Remove
the two plastic connector covers at the top
and bottom of the drive. Each cover is held
by two screws.
• On IT (ungrounded) systems and corner-
grounded TN systems, remove the screw
labelled VAR located close to the supply
terminals.
• Fasten the two cable clamp plates included
to the drive, one at the top, one at the
bottom. The clamp plates are identical.
• Strip the power cables so that the shields are
bare at the cable clamps.
• Connect the supply, resistor (if present) and
motor cables to the appropriate terminals of
the drive.
• Tighten the cable clamps onto the bare cable
shields. Connect the ends of the cable
shields to the ground terminals using cable
lugs. Cover visible bare shield with insulating
tape.
• ACSM1-04xx-024A...090A-4 only: Cut
suitable slots on the edges of the connector
covers to accommodate the cables. Refit the
covers.
• Ground the motor cable shield at the motor
end.
