2 Safety
Danger to life due to fire or explosion when batteries are fully discharged
A fire may occur due to incorrect charging of fully discharged batteries. This can result in death
or serious injury.
• Before commissioning the system, verify that the battery is not fully discharged.
• Do not commission the system if the battery is fully discharged.
• If the battery is fully discharged, contact the battery manufacturer for further proceedings.
• Only charge fully discharged batteries as instructed by the battery manufacturer.
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.
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 600 V or higher.
Risk of burns due to hot inverter enclosure parts
Some parts of the inverter enclosure can get hot during operation. Touching hot enclosure parts
can result in burn injuries.
• During operation, do not touch any parts other than the enclosure lid of the inverter.
• Wait until the inverter has cooled down before touching the enclosure.
Risk of fire
• To reduce the risk of fire, connect only to a circuit provided with maximum branch-circuit
overcurrent protection 50 A in accordance with the National Electrical Code
70 or the Canadian Electrical Code
