Maintenance

The product is low-maintenance. The connections of all DC
cables are designed as maintenance-free, self-adjusting
PUSH IN spring-loaded terminals.
– A visual inspection must be carried out once a year.
– More intensive maintenance and inspection of all com-
ponents must be carried out at least every 5 years.
During maintenance work, make sure that no
moisture, dust or foreign objects can penetrate
into the product.
Two procedures are permitted for maintenance
work:
– Working on live components: Only electricians
who are qualified to work on live components
may work under voltage. They must comply
with local regulations (e.g. personal protective
equipment and risk assessment).
– Voltage-free working: Input and output cables
must be properly disconnected and secured
against being switched on again. Voltage-free
work may be carried out by electricians and
trained personnel.

8.1 Testing the motorised switch

The proper function of the motorised switch must be tested
every three months. Proceed as follows:
► Switch off the inverter.
► Press the optional emergency off button or the circuit
breaker, which will interrupt the supply voltage to the
electronics, terminal block -XD10.
The motorised switch must turn from the on position to the
off position.
► Switch on the supply voltage for the electronics on
again.
The motorised switch must automatically turn from the off
position to the on position.
If it fails this test, proceed as follows:
► Check whether the power supply is correct, the emer-
gency off button is unlocked, and the fuse is switched
on.

► Check the LEDs on the electronics.
LED1: AC supply voltage
On Supply ok
Off Supply off
Flashing Electronics error
LED2: Status of energy storage
On Charged
Off Discharged
Flashing Charging
If LED1 is flashing, proceed as follows:
► Disconnect the supply voltage for the electronics.
► Switch on the supply voltage on again after one minute.
► If the error cannot be removed, please contact your
dealer or distribution partner.

8.2 Annual visual inspection

Imminent danger to life!
Up to 1,100 V DC can be applied to live parts.
The system must be switched off for this work.
► Switch off the system as described in chap-
ter 2.2 on page 25.
► Check the product, all PV connectors, cable glands and
all cables for damage.
► Check the legibility and fixation of the warning symbols
on the enclosure cover. The legibility may be impaired
by weather conditions or UV radiation.
► Check the outer control panel of the switch-disconnector
for damage.
► Check the seal in the enclosure cover. It must be un-
damaged and flexible. A porous seal or cracks can lead
to leaks.
► Check the PCB and all PCB terminals for damage.
► Check the earthing connection for tight fit (observe
torque).
► Check the clamping points on the switch-disconnector
for tight fit.
► In the event of damage, contact your Weidmüller repre-
sentative or distributor.
