9. Maintenance

Regular inspection and maintenance tasks support trouble-
free and safe operation of the device and contribute to
increasing the service life. Thus any fault sources can be
detected early on and hazards can be avoided.
MENNEKES recommends that you visually inspect the device
for external damage (e.g. missing or defective components,
material alterations, etc.) and its proper functioning regular-
ly. If defects are detected on the device they must be recti-
fied without delay. A damaged, faulty device must not be
used because the risk of electric shock or material damage
(e.g. through fire) can be increased).
Danger

components.
• Only execute tasks on the device after you have
disconnected it from the power supply and have
unplugged the plug.
9.1 Maintenance
The maintenance tasks can be executed by non-specialised
persons. However if you are unsure commission a qualified
electrician to perform the tasks.

Checking the screw locking devices

Danger

When replacing a D-type fuse link, energized components
can be touched. There is danger of severe or fatal injury.
• Only replace a D-type fuse link after you have
disconnected the device from the power supply and
have unplugged the power plug.
• If your device is equipped with D-type fuse links check
them for firm seat.
• If necessary, tighten them manually.

Checking residual current devices (RCDs)

The residual current devices (RCDs) can vary in appearance
and operation.
Usually, they are checked by actuating a test button by
means of which the residual current device is triggered.
After triggering, the triggering lever of the residual current
device must be returned to its initial position.
