Danger to life from electric shock if the Sunny Central is damaged
Operating a damaged Sunny Central can lead to hazardous situations that result in death or serious injuries due to
electric shock.
• Only use the Sunny Central when it is in a technically faultless condition and safe to operate.
• Regularly check the Sunny Central for visible damage.
• Make sure that all external safety equipment is freely accessible at all times.
• Make sure that all safety equipment is in good working order.
• Wear suitable personal protective equipment for all work on the Sunny Central.

Danger to life from electric shock if the Sunny Central is not locked
If the Sunny Central is not locked, unauthorized persons will have access to live components carrying lethal voltages.
Touching live components can result in death or serious injury due to electric shock.
• Always close and lock the Sunny Central.
• Remove the keys from the door locks and from the key switch.
• Store the key in a safe place.
• Ensure that unauthorized persons do not have access to the PV system.
Danger to life due to blocked escape routes
In hazardous situations, blocked escape routes can lead to death or serious injury. Opening the doors of two
Sunny Central inverters located opposite each other blocks the escape route. It is imperative that the escape route is
freely accessible at all times.
• An escape route with a passage width of at least 500 mm must be available at all times. Make sure the minimum
passage width of the escape route meets local standards.
• Do not place any objects in the escape route area.
• Remove all tripping hazards from escape routes.
• If two Sunny Central inverters have been installed facing each other, never open the doors of both inverters
simultaneously.
Danger to life from electric shock when entering the PV field
The ground fault monitoring with GFDI, Remote GFDI or Soft Grounding does not provide protection from personal
injury when GFDI is activated. PV modules which are grounded with GFDI discharge voltage to ground. Entering the
PV field can result in lethal electric shocks.
• Configure the PV system as a closed electrical operating area.
• Before entering the PV field, switch the PV array to insulated operation.
• Ensure that the insulation resistance of the PV field is greater than 1 k Ω .
Danger to life from electric shock even if the inverter is disconnected on the AC and DC sides
The precharge unit for the option "Q at Night" will be charged even if the AC contactor and the DC switch are open.
Touching live components of this assembly will result in death or serious injury.
• Do not touch any live components.
• Do not remove protective covers.
• Observe the warning messages.
• Wear personal protective equipment.
