5. MAINTENANCE / FUSE REPLACEMENT
5.1
Maintenance
Your Phoenix inverter does not need any specific maintenance besides checking all DC and AC
connections at least once a year. Check if all nuts and bolts in the electrical system are still
tightened sufficiently and if that cables are in good condition. Keep the inverter reasonably clean
and remove dust/fibres gathered at the fan in- and outlets to avoid airflow obstruction.
5.2
Replacing fuses
The inverter is equipped with two internal fuses, one on the DC side and one on the AC side.
These fuses will only blow in case of serious malfunction and/or external inverter abuse like
reverse polarity of battery connections. Both fuses can be accessed by removing the cover of the
enclosure as described below.
BEFORE OPENING THE INVERTER TO REPLACE A FUSE, ALWAYS
DISCONNECT THE BATTERY FROM THE INVERTER FOLLOWED BY
DISCHARGING THE INTERNAL CAPACITORS BY PUSHING THE POWER
SWITCH (OF THE DISCONNECTED INVERTER) IN THE 'I' POSITION FOR 10
SECONDS.
CAUTION
1. Unscrew the 8 top cover screws (4 on each side, see picture below) to lift the top cover enabling
access to the internal fuses. To make removing the top cover easier, it is advisable to slightly
unscrew the remaining left- and right screws on one side of the inverter.
Remove these four screws at both
ends of the inverter enclosure
2. Now the top side of the main PCB is visible as well as the location of the two fuses. See the
figure below for the fuse locations.
