Note
The insulation resistance is strongly dependent
on the temperature! If the insulation resistance is
too low, the motor must be dried.
To do this, heat the motor with warm air (80 °C
max.). You can end the drying procedure when
the minimum insulation resistance (see Fig. 1) is
exceeded.
Check the terminal box to see whether:
• the interior is dry and clean
• connections and fasteners are corrosion-
free
• the cover seal is intact
• the cable screw connections are tight.
If not, then dry, clean or replace the damaged
parts.

Installation of the drive

3.1

Preparations

The motor is normally supplied complete with the
front bearing ("A" side).
Clean the corrosion protection agent thoroughly
from the shaft and shaft ends. Be sure that the
solvent does not get into the bearings.
Clean the flange surfaces on the pump case and
bearing skirt.
Check to be sure that the flange connection of
the pump or bearing skirt and the drive motor
match in size.
Check whether the protection class of the motor
conforms to the requirements on site or of the
system.
Uninstall the parts which are to be re-used from
the old drive, such as the impeller, bearing ring
seal, shaft protection sleeve, etc.
Examine all of the uninstalled parts which you
intend to re-use for wear and visible damage.
Replace defective parts with new ones.
3.2

Installation

Place the motor on the connecting flange of the
pump case or the opposing flange of the bearing
skirt. Be sure that it is correctly seated.
Antriebe Typ 63 - 200L
Version: 27217 / A
Centering shoulder tolerance of the flanges
according to DIN 42948
ISO j6 with Ø ≤ 230 mm
-
- ISO h6 with Ø > 230 mm
Tightening
crosswise. The tightening torque depends on the
screw diameter and should in no case be
exceeded
Tightening torques for coarse pitch threads
DIN 13
Screw class:
Screw Ø M8
Screw Ø M10
Screw Ø M12
Screw Ø M16
The specifications apply to new screws,
ungreased. Utilization of the screw yield point of
90%.
Install the parts which were removed from the old
drive on the motor shaft. When doing so, follow
the installation
instructions for the pump = sections 4.2 and 4.3.
After completing the installation check the free
operation of the motor by hand by turning the
impeller of the pump through the intake opening.
If this work is free of objection, the pump can
again be installed in the pipeline system.

Electrical connection

4.1

General

It is essential that the following points be
followed:
• If possible position the terminal box so that
the cable entries point downward.
• Use only properly fitting screw cable
connections and tighten them well;
• Clean sealing surfaces of terminal box and
cover. Replace defective seals. Stick seals
onto one side.
• When using motors with incorporated
thermal motor protection, the cold
contactors must always be connected.
Otherwise the warranty will cease.
