Anti-condensation heating (optional)
Motors whose windings are at risk of condensation due to the cli-
matic conditions, e.g. inactive motors in humid atmospheres or
motors that are subjected to widely fluctuating temperatures can
be equipped with anti-condensation heaters as an option.
Anti-condensation heating must not be switched on during oper-
ation. For this purpose, an appropriate interlocking circuit with
the main switch of the machine must be installed when erecting
the electrical system.
For additional protection against the build-up of condensation, it
is recommended that the cooling circuit of a water-cooled ma-
chine is shut down during long periods of inactivity.
The anti-condensation heating available as an option must prin-
cipally be switched on 1 hour after shutdown of the machine to
prevent damage to the winding insulation.
For the connection of auxiliary leads, separate auxiliary terminal
boxes can be mounted as an option (option M52).

Marine version (optional)
Motors for operation in a marine climate (saline sea air contain-
ing up to 1 mg salt/m
3
of air and 96% air humidity) can be sup-
plied in a “Marine version” as an option. To prevent corrosion at
the bearing seal, the shaft section under the bearing seal is
coated.
For installation on deck, forced-ventilated motors must be pro-
tected against flooding. The motors must also be protected
against ice formation at temperatures below 0 °C (precautions
must be taken against the external fan freezing solid or against
freezing of the cooling water).
Standards and regulations
The motors comply with the appropriate standards and regula-
tions, especially those listed in the table below.
