put AC-OUT is allowed.
!
WARNING! Electrocution hazard
Follow prescribed standards and guide-
lines depending on the installation situa-
tion. The appropriate protective device
must be used. When used with a resid-
ual-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 (exter-
nal 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-sec-
tion to avoid damage caused by overheating or
fire.
➤Check cables for damage after installation and
secure against tensile stress with suitable
counter-measures.

Operation

The device operates without any handling from the
user. The device detects power input and switches
automatically as soon as a change of the input sup-
ply is detected. The monitoring automatically
detects whether the external 230 VAC mains volt-
age is available and supplies it directly to the 230 V
sockets. If the external 230 VAC mains voltage is
not present, the unit shifts and the interior sockets
are supplied from the inverter.

Cleaning and maintenance

The device is maintenance-free.
➤Occasionally clean the product with a damp
cloth.

tions and has received safety training to
