6 OPERATION AND MAINTENANCE
This chapter describes the operation of one single inverter.
6.1 GENERAL
After installation and commissioning the CS inverter will
switch on automatically if solar irradiation is sufficient. The
CS inverter operates automatically: there is no need to
operate it manually. If the irradiation of the PV modules is
insufficient, for instance at night, the CS inverter switches
off automatically. The LCD screen however stays operational
as long as AC power is available. No live measurements are
available in this situation.
6.2 MAINTENANCE
Switch off the DC switch before any
maintenance takes place!
6.2.1 Cleaning
Cleaning of the CS inverter enclosure is not necessary under
normal circumstances. If cleaning is still preferable, use a
soft damp cloth to clean the enclosure of the CS inverter.
Never use any aggressive or abrasive cleaning agents. Use
of high pressure cleaning equipment is prohibited as it may
damage the sealing.
High Pressure cleaning of the Sumaster CS
is not allowed!
6.2.2 Fan module
Only remove the fan module when the CS
inverter is switched off.
The fan module (gure 6-1) needs checking and cleaning
every 12 months, in dusty environments checking is needed
more often. Unscrew the 4 hand screws as indicated.
Carefully move out the fan module, bottom first and unplug
the four fans before removing the module completely. If
necessary, clean the fans using compressed air.

6.2.3 Air outlet
The CS inverter is provided with wire mesh behind the air
outlets (fig. 6-2).
Figure 6-2: Removing the air outlets
Remove the two air outlets by unscrewing the two Phillips
screws on top. Clean if necessary.
6.2.4 Electrical connections
Have your electrical installation checked by a
qualified installer at least once a year. Defects such as
loose connections, burnt wiring etc. must be corrected
immediately.
6.3 DE-COMMISSIONING
If it is necessary to put the CS inverter out of operation,
follow the instructions in order of succession as
described below:
CAUTION!
Follow below mentioned instructions in order
of succession as described.
1 Switch Off the DC switch
2 Cut off the grid voltage by switching off the AC
circuit breaker
3 Release the AC connector
4 Release the DC connectors. A special tool may be needed
to release the DC connectors.
5 Disconnect the ground (PE) connection
Now the SunMaster CS can be demounted in a safe way.
CAUTION!
Never release the DC plugs during operation
of the CS inverter. A spark or an electric arc
may develop, in which case both plug and
socket of the CS inverter must be replaced.
CAUTION!
Be sure to disconnect all other cables before
disconnecting PE.
