1.
Validity
This additional installation, operation, and maintenance manual is valid for water cooled mo-
tors (M3LK 250) and is to be read together with the main manual (Low Voltage Motors/Man-
ual). Additional information may be required for some machines due to special application
and/or design considerations.
Usage:
Normally, water cooled motors are manufactured to specific customer requirements. How-
ever, these instructions refer to ’standard’ water cooled motor versions.

Safety Instructions
2.1.
General
General safety regulations, safety precautions and specific agreements made for each work
site shown in this document must be observed all times.
2.2.
Intended Use
Electric machines have dangerous live and rotating parts and may have hot surfaces. All oper-
ations serving transport, storage, installation, connection, commissioning, operation and
maintenance should be carried out by skilled personnel (in conformity with EN 50 110-1 / DIN
VDE 0105 / IEC 60364). Improper handling may cause serious personal injury and damage to
property.
These machines are intended for use as components for industrial and commercial installa-
tions as defined in the Machinery Directive (MD) 89/392/EEC. Commissioning is prohibited
until conformity of the end product with this directive has been established (follow particular
local safety and installation rules e.g. EN 60204).
These machines comply with the harmonized series of standards EN 60034 / DIN VDE 0530.
Their use in hazardous areas is prohibited unless they are expressly designed for such use.
Air-cooled models are typically designed for ambient temperatures of -20°C or -25°C up to
+40°C and altitudes of 1000 m above sea level, (Please refer to product specific instructions.
Ambient temperature for air-/water-cooled models should be no lower than +5°C without wa-
ter/glycol-based mixture for coolant. Do take note of deviating information on the rating
plate. Field conditions must conform to all rating plate markings. NOTE – Delete this section
once done!
2.3.
Transport storage
Report damage immediately to the transport company if damage is discovered upon delivery
and stop commissioning, if necessary. Lifting eyes are only dimensioned for the weight of the
machine, therefore do not apply extra loads. Ensure the use of correct lifting eyes and if
needed, use suitable lifting equipment (e.g.rope guides). Remove shipping braces (e.g. bear-
ing locks, vibration dampers) before commissioning and store these for further use.
When storing machines make sure that the location is dry, and free from dust and vibration
to avoid bearing damage. Measure insulation resistance before commissioning. Limit values
