2.3 Safety Precautions
Electric Shock
High voltages are present in the off-grid system and in the off-grid inverter. The off-grid inverter can
start automatically from standby mode. Work on electrical connections of the off-grid inverter must be
performed by a skilled person. Observe the following safety instructions before working on the
electrical connections:
• Turn off or disconnect the following components in the specified order:
– Off-grid inverter
– All loads, AC sources, external energy sources and DC sources
– Miniature circuit-breakers and switch-disconnectors for AC sources and the external energy
source in the sub-distributions
– BatFuse switch-disconnector
• Ensure that the device cannot be reconnected.
• Open the enclosure lid and ensure that no voltage is present.
• Earth and short-circuit the AC conductors.
• Cover or safeguard any adjacent live components.
Explosion
Explosive gases may escape from the battery.
• Do not allow open flames, embers, or sparks near the battery.
• Maintain and operate the battery according to the manufacturer's specifications.
• Do not throw batteries into fire.
Acid Burns and Poisoning
If handled inappropriately, electrolyte from the battery can burn the skin or eyes and/or be toxic.
• Protect the battery enclosure against destruction.
• Do not open or deform the battery.
• Whenever working on the battery, wear rubber gloves, rubber boots and goggles.
• Rinse acid splashes with clear water and consult a doctor.
• Maintain and operate the battery according to the manufacturer's specifications.
Crushing
Moving parts in the generator can crush or sever body parts. The generator can be started
automatically by the off-grid inverter.
• Only operate the generator with the safety equipment.
• Maintain and operate the generator according to the manufacturer's specifications.
