• The operating elements can be accessed
once the transparent housing cover has
been removed. The housing cover may be
removed for operational purposes, but it
only makes sense for service work.
• The protective rating given is reduced
when the cover is removed (water-tightn-
ess). Before removal, it must be checked
whether there is a hazard through high
humidity or splashwater. In this case, the
control unit must be switched voltage-free
first. In case of doubt, a qualified electrici-
an must be consulted.
• The current set at the motor protection
switch must correspond with the rated cur-
rent of the connected motor and must not
be adjusted by the operator.
• Following operation, the housing cover
must be sealed properly again to guaran-
tee the protective rating (water-tightness).
