!
WARNING! Electrocution hazard
Before any work on the 230 VAC wiring is performed, switch off all dangerous voltage.
Ensure that no accidental switching on or plugging in of mains voltage is possible.
!
WARNING! Electrocution hazard
Never put cables for 12 VDC voltage and 230 VAC voltage in the same cable duct.
➤ Connect the cables according to the wiring diagram (fig. 3, page 5).
Connect the cables through the existing rubber sleeves, protected outside against tensile
loads and vibration. The diameters of the cables must correspond to the diameter of the rub-
ber sleeves in order to comply with the IP rating.

!
WARNING! Electrocution hazard
Follow prescribed standards and guidelines depending on the installation situation.
The appropriate protective device must be used. When used with a residual-current
device (RCD), N and PE must be short-circuited at the 230 V output of the inverter.
The transfer switch will prioritize input AC1-IN (external mains input) prior to input AC2-IN (inverter).
➤ Make sure that the inverter applied is equipped with a safety isolation (galvanic isolation)
between input (battery voltage) and AC output (230 VAC).
Connected cabling must have sufficient cross-section to avoid damage caused by overheating or
fire.
➤ Check cables for damage after installation and secure against tensile stress with suitable
counter-measures.
