8.2 Maintenance

Risk of burns due to hot components
Some components (e.g. heat sink) inside the
inverter can become hot during operation.
Touching hot components can cause burns.
• The inverter is to be installed in such a way that
hot components cannot be touched.
• After opening the product, wait until the
components have cooled down.
• Wear suitable personal protective equipment
for all work on the product.
1. Ensure that the heat sink at the rear of the inverter
is not covered.

Measures
Replace AC surge protection
device. See SPD replacement
instructions for details.
Restart the inverter. If the event
persists, contact Service.
Contact Service.
Contact Service.
Warning: Do not operate the DC
load-break switch of the inverter.
Switching off the DC voltage using a
suitable DC load-break switch in the
Combiner Box is still possible. Do
not perform any further actions or
switching operations on the inverter.
Contact Service immediately.
Contact Service.
2. Clean the contacts of the PV load-break switch
once a year. Clean by cycling the switch to on
and off positions ten times. The PV load-break
switch is located at the bottom of the inverter.
3. For correct operation and a long service life,
ensure free air circulation for the following areas:
– around the heat sink at the top and side of
the inverter where the air exhausts, and
– towards the fan on the underside of the
inverter.
4. To clear obstructions, clean using compressed
air, a soft cloth, or a brush.
