5.1 Connecting and disconnecting Solar Inverter
CAUTION
Ensure proper mechanical and electrical installation before commissioning
the Solar Inverter.
Check the cables to ensure that they are in sound condition.
Always disconnect the mains connection first by switching off the correspon-
ding mains fuse and before disconnecting the solar generator side by ope-
ning the DC load break switch.
The Tyco Solarlok connectors on the solar generator side must not be discon-
nected under load. First turn the DC load break switch to position 0.
NOTE
The Solar Inverter is supplied from the grid. The Solar Inverter switches on au-
tomatically when sufficient solar generator output is available. Corresponding
switch-on and switch-off thresholds have been defined for this purpose.
Connecting 1. Establish the grid connection via the external circuit breaker.
2. Switch on the solar generator voltage by closing the DC load break switch
(switching position 1). The Solar Inverter starts operating when the input
voltage level is adequate.
