Note:
• The brake connections are assigned only if the motor was
manufactured with the "brake" option.
• Only one of the PTC thermistor connector pairs (3-4 or 5-6)
in the motor cable should be connected to the motor; the
other one pairs serves a spare.
• Do not remove or damage the seal glued into the cover.
• Observe the size of the screwed cable connection and
connection thread for the cable inlet into the terminal box.
• In particular, heed a sorted and de-energized laying of the
connection cables within the terminal box to avoid abrasion
or pressure marks on the cables.
• The connections of the motor-windings in the terminal box
must not be removed.
