Re-assembly

Re-assembly instructions

If possible, assemble the machine on a surface plate. This ensures that the feet surfaces are

all on the same level.

NOTICE

When mounting the end shield, make sure that the windings that project from the stator

housing do not become damaged.

NOTICE

Take great care and pay attention to cleanliness when fitting and assembling the bearings.

Sealing measures when reassembling

Due to the stricter requirements of degree of protection IP55, joint sealant must be used for

motors from the 1PH7 series.

Clean bare joints between parts before reassembling (e.g. between enclosures, end shields

and the active parts of bearings).

Coat the bare joints between parts with a non-hardening sealant (e.g. MARSTON

HYLOMAR SQM32M).

Note

MARSTON HYLOMAR SQM32M sealant can be ordered from W. Kopp, Schlesierstrasse 9,

97268 Kirchheim, Germany, or directly from Marston Bentley Domsel GmbH,

Bergheimer Str. 15, 53909 Zülpich, Germany.

Release the retaining screw.

Press the screw M10 onto the original screw. This causes it to fall out.

Remove the sensor.
