• the entries on the nameplate of the drive match the voltage supply system,
• the drive is undamaged (no damage caused by transport or storage).
• it is certain that the following requirements have been fulfilled:
– Ambient temperature between –25 °C and +40 °C (remember that the tempera-

Mounting
MOVIMOT
®
• The MOVIMOT
®
may only be mounted or installed in the specified mounting position
on a level, vibration-proof and torsionally rigid support structure.
• Thoroughly remove anti-corrosion agents from the shaft extensions (use a commer-
cially available solvent). Do not allow the solvent to penetrate the bearings and shaft
seals – this could cause material damage!
• Carefully align MOVIMOT
®
and the driven machine, to avoid placing any unaccept-
able strain on the motor shafts (observe permissible overhung load and axial thrust
data!).
• Do not butt or hammer the shaft end.
• Use an appropriate cover to protect motors in vertical mounting positions from ob-
jects or fluids entering!
• Ensure an unobstructed cooling air supply and that air heated by other apparatus
cannot be drawn in or reused.
• Balance components for subsequent mounting on the shaft with a half key (output
shafts are balanced with a half key).
• Any condensation drain holes are closed with plastic plugs and must not be opened
unless needed.
• Do not leave any condensation drain holes open, since this defeats higher enclosure
ratings.
Installation in
damp areas or in
the open • Use suitable screwed cable glands for the supply leads (use reducing adapters if
necessary).
• Coat the threads of cable glands and pocket caps with sealant and tighten them well
– then coat them again.
• Seal the cable entry well.
• Clean the sealing faces of the MOVIMOT
®
inverter well before re-assembly.
• Restore the anticorrosive coating if necessary.
• Check the type of enclosure is authorized (refer to the nameplate).
