DANGER
Risk of sustaining injury due to electric shock
Danger of severe or fatal injury when contact is made
with live components.
Disconnect the device from the voltage supply.
Tasks to be performed
Check the device for defects.
Properly rectify any defects or damage.
For repairs only use original spare parts from MENNEKES.
Check the device for correct functioning.
If re-commissioning the device is not likely due to defects,
and with regard to further safe use, the device must no
longer be put into service.
Performing voltage tests
When voltage tests are carried out on electrical installations
equipped with AC/DC sensitive residual current devices (FI/
RCDs) of type B/B+, these could sustain damage due to
incorrectly performed tests.
ATTENTION
Material damage of protective element due to incor-
rectly performed test
Incorrectly performed tests can damage protective elements.
In the case of voltage tests with test voltages
> 0.5
kV
,
switch off the
residual current devices (FI/RCDs)
and the
upstream and/or downstream circuit brea-
kers
.
Observe the circuit diagram.
Observe the circuit diagram for the power dis-
tribution box for voltage testing.
