l
All control inputs and Outputs of the controller are mains-
isolated. The mains isolation has a insulation. The control
inputs and Outputs must be integrated into another of
against contact.
Use insulated operating elements, connect the mechanical
screw
of the potentiomenter (accessory kit)
with PE.
l
Unused control inputs and Outputs must be protected with plugs
or the

When using current-operated protective equitpment:
The are internally equipped with a mains rectifier.
As result, a DC-fault may prevent the tripping of the
current-operated protective equipment after a short-circuit to
frame.
Therefore, we recommend additional measures such as
protective multiple
or universal-current sensitive
current-operated
When dimensioning the tripping of current-operated
please observe, that the capacitive leakage currents
between and RFI may result in false
tripping.
l
The regulations the of PE
conductors must be observed. The of the PE
conductor must be at least as large as the of the
connection.

Before first switching-on of the controller check whether there is
an
fault at the output side, if so, remove it. faults
occur Operation will be detected, the controller will
be switched off and indicate the fault message
l
The internal limitation be overloaded when
connecting or disconnecting the controller very often. With cyclic
mains connection, the Controller be switched on every 3
minutes.
l
Replace fuses only with the specified type and when
no voltage is applied.
The controller remains live for up to 3 minutes after mains
disconnection.
