WARNING
Danger to life and limb due to electrical power! Handling within the range
of live parts is extremely dangerous. Therefore:
● Any work required on the electric system may be carried out only by skilled
electricians. It is absolutely necessary to use power tools.
● Before starting work, the system must be de-energized and the power
switch be secured against unintentional or unauthorized re-energization.
● Before starting work, the appropriate measuring equipment must be used
to check whether parts of the system are still applied to residual voltage
(e.g. caused by capacitors, etc.). If yes, wait until these parts have dis‐
charged.
Injuries to persons or property possible! Interrupting or connecting live
lines may cause unpredictable dangerous situations or lead to physical
damage. Therefore:
● Connect and disconnect plug connectors only when they are dry and de-
energized.
● During operation of the system, all plug connectors must be securely
tightened.
Risk of short-circuit caused by liquid coolant or lubricant! Short-circuits
of live lines may cause unpredictable dangerous situations or lead to
physical damage. Therefore:
● Provide open mating sides of power plug connectors with safety caps
when installing or replacing drive components if you cannot exclude that
they might be moistened with liquid coolant or lubricant.
Damages to the terminal box or the cable are possible!
Too high tightening torques can damage the bolt-on fixing or can squeeze the
cable. If bolt-on fixings are damaged, the protection IP65 on the terminal box
cannot be ensured any longer.
● In fact of this use no automatic screwdriver (e.g. electronical, pneumatic
or hydraulic screwdriver).
MKE motors in EU design are equipped with terminal boxes that are optimised
for the storage of ready-made Rexroth cables.
In case of MKE motors, ignition cleavages are a positive Ex protection
measure. Perfect compliance with the ignition cleavage tolerances ensures
that, under a fault condition, ignition sparks cannot leave the motor's inner
chamber to the outside. The terminal box cover forms an ignition cleavage with
the motor housing which has to be opened and closed again during assembly
and disassembly of the terminal box cover. Work carefully! Replace damaged
terminal box covers.
Mount the ready-made cables in the following order:
