CAUTION
Foreign bodies in the cooling circuit
Foreign bodies in the cooling system can cause blockages in individual circuits. This can
cause water-cooled components to overheat and ultimately failure of the motor.
For this reason, make sure that no foreign bodies can enter the water circulation system.
Do not remove the protective cover until you are ready to make the final water connections.
CAUTION
Frost danger
Damage may be caused to the cooling circuit if the cooling water freezes at temperatures
below 0°C. Before transporting and storing a water-cooled 1FW4 motor, ensure that the
cooling system has been completely drained:
• Drain the cooling ducts.
• Blow out the cooling ducts with compressed air.

3.3 Installation
Instructions relevant to safety
CAUTION
High surface temperature
The surfaces of the 1FW4 motors can have temperatures > 80°C. This is the reason that
temperature-sensitive components, e.g., cables or electronic components may neither be in
contact nor be attached directly to the motor.
Provide a contact guard. When arranging cables or other components on the motor
housing, take the increased temperatures of these housing components during operation
into consideration.
When installing, make sure the connecting cables are
• Not damaged
• Not under tension
• Unable to come into contact with any rotating parts
Observe the technical data in these operating instructions and on the rating plate!
If any transport locks are in place, remove them before installation.
