[3.2] AC Connection
Risk of death or injury due to electric shock!
While the inverter is connected to grid (AC
voltage source) and to the battery (DC voltage
source), high voltage is present in cables and
inner parts of inverter.
•
Important: All voltage sources ( DC / battery and AC
/ utility grid) must be disabled before any electrical
work.
To disable battery DC voltage connection turn battery
switch to 0-position and wait 10 minutes before
continuing.
To disable AC voltage connection turn off AC switch,
main breaker or fuse. Make sure, other
persons don’t
switch back.
Do not enable voltage connections until work is finished.
•
During DC-connection: Never touch positive and
negative cable ends simultaneously!
•
During AC connection: Do not exchange L, N and PE
wires!
•
Make sure other persons keep away during electrical
work
Risk of death or injury due to electric
arc!
Disconnecting DC plugs under load can
cause electric arcs.
Risk of damage due to improper
installation and operation or misuse.
•
Contact local utility company or grid operator
before connecting inverter to grid.
•
Provide for an AC disconnection device
(typical miniature circuit breaker 3 pole 6kA,
B-characteristic 16A).
•
If required in country or installation, install a
residual-current device (RCD), or residual-
current circuit breaker (RCCB).
•
Inverter contains no owner serviceable parts.
Contact local authorized personnel for service.
•
Do not remove name plate.
•
Only RCT Power certified batteries complying
with the demands of the certain region are
allowed to be used.
