7.3 Repair

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.

Notice

Please note that these joints between parts (e.g. the sealing gap between the enclosure and

end shield) must also be resealed with a suitable, silicone-free sealant during assembly.
