Installing MOVIMOT

NOTICE
Loss of guaranteed degree of protection if the MOVIMOT
®
inverter is installed incor-
rectly or not at all.
Damage to the MOVIMOT
®
inverter.
• When removing the MOVIMOT
®
inverter from the connection box, it must be pro-
tected from dust and moisture.
Observe the following notes and regulations for mounting the MOVIMOT
®
drive:
• Only install the MOVIMOT
®
drive on a level, low-vibration, and torsionally rigid sup-
port structure.
• Observe the permitted mounting position on the drive nameplate.
• Thoroughly remove any anti-corrosion agent from the shaft end. Use a commercial-
ly available solvent. Do not allow the solvent to penetrate the bearings and sealing
rings (damage to the material).
• Align the motor carefully to avoid placing any unacceptable strain on the motor
shafts. Observe the permitted overhung and axial loads specified in the
"MOVIMOT
®
gearmotors".
• Do not jolt or hammer the shaft end.
• Use an appropriate cover to prevent objects or fluids from entering motors in verti-
cal mounting positions.
• Ensure sufficient clearance around the unit to allow for adequate cooling air supply.
Ensure that exhaust air warmed by other devices cannot be drawn in.
• Balance components that were subsequently mounted to the shaft with a half key
(output shafts are balanced with a half key).
• The condensation drain holes are sealed with plastic plugs. Unplug them only if
necessary.
Open condensation drain holes are not permitted. If condensation drain holes are
open, higher degrees of protection no longer apply.
