Mechanical Installation
4.3
Mounting the MOVI-SWITCH
®
drive
Observe the following mounting instructions:
•
Install the MOVI-SWITCH
®
drive only in the specified mounting position on a level,
vibration-free, and torsionally rigid support structure.
•
Adhere to the mounting position specified on the motor nameplate.
•
Thoroughly remove any anti-corrosion agent from the shaft end. Use a commercially
available solvent. Do not allow the solvent to penetrate the bearings and shaft seals
– this could damage the material.
•
Align the motor carefully to avoid placing any unacceptable strain on the motor
shafts. Observe the permitted overhung and axial forces.
•
Do not jolt or hammer the shaft end.
•
Use an appropriate cover to prevent objects or fluids from entering motors in vertical
mounting positions.
•
Ensure sufficient clearance around the unit to allow for adequate cooling. Avoid the
drawing in of warm outlet air of other units.
•
Balance components that were subsequently mounted to the shaft with a half key
(output shafts are balanced with a half key).
•
Existing condensation drain holes are sealed with plastic plugs. Only open them, if
necessary.
•
Open condensation drain holes are not permitted. If condensation drain holes are
open, higher degrees of protection are no longer possible.
4.4
Installation in damp locations or in the open
Observe the following notes for mounting the MOVI-SWITCH
®
drive in damp areas or
in the open:
•
Use suitable cable glands for the cables. Use reducing adapters, if necessary.
•
Coat the threads of the cable glands and filler plugs with sealing compound and
tighten them properly. Then coat the cable glands again.
•
Seal the cable entries properly.
•
Before installing the MOVI-SWITCH
®
motor starter again, clean its sealing surfaces
thoroughly.
•
If the corrosion protection coating is damaged, restore the coating.
•
Check whether the degree of protection specified on the nameplate is permitted in
the ambient conditions on site.
NOTICE
Loss of warranted degree of protection if the MOVI-SWITCH
®
motor starter is installed
incorrectly or not at all.
Damage to the MOVI-SWITCH
®
motor starter.
•
When you remove the MOVI-SWITCH
®
motor starter from the connection box, you
must protect it from moisture and dust.
