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 1000 V or higher.
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.
Risk of injury due to weight of product
Injuries may result if the product is lifted incorrectly or dropped while being transported or
mounted.
• Carry and lift the product upright with the help of several people. Take the weight and the
center of gravity of the product into account. The center of gravity is on the side of the AC-
Connection Unit.
• Wear suitable personal protective equipment for all work on the product.
• Transport the product using the carrying handles or hoist. Take the weight of the product
into account.
• Use all carrying handles provided during transport with carrying handles.
• Do not use the carrying handles as attachment points for hoist equipment (e.g. straps, ropes,
chains). Insert eye bolts into threads provided on top of the product to attach the hoist
system.
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.
• 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).
