DANGER
Danger to life due to electric shock when touching live system components in
case of a ground fault
If a ground fault occurs, parts of the system may still be live. Touching live parts and cables
results in death or lethal injuries due to electric shock.
Disconnect the product from voltage sources and make sure it cannot be reconnected
before working on the device.
Touch the cables of the PV array on the insulation only.
Do not touch any parts of the substructure or frame of the PV array.
Do not connect PV strings with ground faults to the inverter.
Ensure that no voltage is present and wait five minutes before touching any parts of the PV
system or the product.
CAUTION
Risk of burns due to hot enclosure parts
The enclosure and the enclosure lid may get hot during operation. The DC load-break switch can
not become hot.
Do not touch hot surfaces.
Wait until the inverter has cooled down before touching the enclosure or enclosure lid.
CAUTION
Risk of fire
To reduce the risk of fire, connect only to a circuit provided with 100A maximum branch-
circuit overcurrent protection in accordance with the National Electrical Code
®
(NE, ANSI/
NFPA 70).
NOTICE
Damage to the enclosure seal in subfreezing conditions
If you open the product when temperatures are below freezing, the enclosure seals can be
damaged. Moisture can penetrate the product and damage it.
Only open the product if the ambient temperature is not below -5°C (23°F).
If a layer of ice has formed on the enclosure seal when temperatures are below freezing,
remove it prior to opening the product (e.g. by melting the ice with warm air). Observe the
applicable safety regulations.
