WARNING
Danger to life due to burns caused by electric arcs through short-circuit
currents
Short-circuit currents in the battery can cause heat build-up and electric arcs. Heat build-up and
electric arcs may result in lethal injuries due to burns.
• Disconnect the battery from all voltages sources prior to performing any work on the
battery.
• Observe all safety information of the battery manufacturer.
WARNING
Danger to life due to electric shock from destruction of the measuring device
due to overvoltage
Overvoltage can damage a measuring device and result in voltage being present in the
enclosure of the measuring device. Touching the live enclosure of the measuring device results in
death or lethal injuries due to electric shock.
• Only use measuring devices with a DC input voltage range of 1000V or higher.
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 injury due to weight of product
Injuries may result if the product is lifted incorrectly or dropped while being transported or
mounted.
• Transport and lift the product carefully. Take the weight of the product into account.
• Always have two persons mount and disassemble the product.
• Wear suitable personal protective equipment for all work on the product.
NOTICE
Damage to the DC connectors due to the weight of the product
The DC connectors mounted on the product may be damaged if the product is set down on
them.
• Do not set the product down on its DC connectors.
• Do not remove the protective cover from the DC connectors until the product is installed on
the wall mounting bracket.
