DANGER
Risk of death due to electrical shock and discharge!
The PV generators/cables may be live as soon as they are exposed to light.
WARNING
Serious burns due to arcs on the DC side!
During operation, dangerous arcs can occur when pulling or plugging the DC connec-
tions.
Before connecting the DC connectors, de-energise the DC side. DC switches must be in
the OFF position.
WARNING
Risk of fire due to improper installation!
Incorrectly fitted plugs and sockets may heat up and cause a fire.
During installation, be sure to follow the manufacturer's requirements and manual. Prop-
erly mount plugs and sockets.
Please note the following points before connecting the PV modules:
■
Our planning tool KOSTAL Solar Plan should be used to optimally configure the solar
modules and achieve the highest possible yields.
■
Check the planning and the wiring of the modules for plausibility.
■
Measure and record the DC idling voltage and polarity of the PV modules. The idling
voltage of the PV modules must be in the voltage range between U
PIKO CI
■
Make sure that the maximum short-circuit current of the PV modules is less than the
permitted value.
■
Make sure that the PV modules are not short-circuited.
