Grounding Conductor
DANGER
Danger of explosion due to improper handling
when connecting the motor!
⇒
The ground conductor on the motor must be
additionally connected to the protective conductor
with a separate cable with 4 mm² cross-section.
The motors for areas subject to explosions have an additional ground lug
on the motor flange for this purpose. Use the grounding cable to connect
the ground-reference lug of the motor with the ground reference of the
machine or system and tighten the screw connection.

Coolant Connection to MAD Motors
MAD motors with explosion-protection design are prepared with a fan
cowl for operation with an external fan.
Note:
The required fan and corresponding connection materials (air
hose, connection clamps, etc.) do not belong to the scope of
delivery of the motor; these must be provided by the machine
manufacturer.
MAD motors may be operated only if the fan provides the specified
minimum amount of air flow on the motor side. Therefore, when selecting
radial fans or central ventilation systems, already take the installed hose
