Risk of converter damage or personal injury due to incorrect service!
Before any service work, observe the following procedure.
•
Wait for at least 5 minutes until all electricity has been discharged from the
internal battery storage components before any maintenance or repair work
is carried out inside the equipment.
•
Use testing equipment to make sure that there is no voltage or current.
When performing electrical connection and maintenance work, temporary
warning signs or barriers must be posted to prevent unrelated persons from en-
tering the electrical connection or maintenance area.
Do not reboot the converter until all faults that may affect the safety of the con-
verter operations are cleared.

change the internal components of the converter unless you are authorized to
do so.

nents as you may damage the device.
