NOTICE
Damage to insulation
If the critical insulation resistance is reached or undershot, this can damage the insulation
and cause voltage flashovers.
● Contact the Service Center (Page 129).
● If the measured value is close to the critical value, you must subsequently check the
insulation resistance at shorter intervals.
Limit values of the anti-condensation heating insulation resistance
The insulation resistance of the anti-condensation heating with respect to the machine housing
should not be lower than 1 MΩ when measured at 500 V DC.
5.1.4 Preparing the mating faces
Prepare the foundation faces dependent on the machine type:
● Mounting on a foundation
– Ensure that the foundation faces are flat and free of contaminations.
– Check the dimensions of the mounting-foot holes.
● Flange connection
– Clean the flange before installation. Ensure that the flange surfaces are flat and perfectly
clean.
– Check the geometry of the flange.
● Wall mounting
– Ensure that the wall faces are flat and free of contaminations.
– Check the dimensions of the mounting-foot holes.
– Support the machine from below, e.g. using a wall bracket or by bolting it.
5.2 Lift the machine to where it will be installed, and position it
5.2.1 Preconditions for correct alignment and secure attachment
Detailed specialist knowledge of the following measures is required in order to correctly align
and securely fit the equipment.
● Preparing the foundation
● Selecting and mounting the coupling
