Parallel INV operation:
• Switch off the INV, switch on miniature circuit-breaker F1
• Set the DIL switches
• Insert the AC fuses
• Connect the DC supply
• Switch on all INVs one after the other
• (The output contactors K7 of the INVs start at the same time as

• (The output contactors K7 of the INVs start at the same time as
soon as n-R INV have been switched on)
• Connect the load
Individual or parallel operation with SBS
• Switch off the INVs, switch on miniature circuit-breaker F1
• Set the DIL switches (INV and SBS)
• Engage the AC fuses (INV output)
• Engage the AC mains and output fuses of the SBS
• Disconnect the manual bypass
• Connect the load
• Connect the DC supply
• Switch on all INVs one after the other
(The K7 output contactors of the INVs start at the same time as soon
as the last INV has been switched on and the INVs have
synchronised to the mains.)

NOTE:
Before switching on the INVs in parallel operation, or the SBS,
make sure the setting of the DIL switches is correct (see
chapters 3.9 and 4.11)!
INVs in parallel operation must be set to the same output voltage,
to the same number of INVs in the system and to different
addresses!

5.4 Disconnection
Even when switched off, the inverter can still be live due to charged
capacitors and external signals. For this reason the terminals must be
tested prior to dismantling the unit to ensure that they are
de-energised.
capacitors and external signals. For this reason the terminals must be
tested prior to dismantling the unit to ensure that they are
de-energised.
The capacitors can be discharged via an external resistor on
terminals X2 or X1: L+ and L-.

• Switch off the AC fuses, if present

NOTE:
Before switching off an INV in the parallel system, check whether
the remaining INVs can take over the entire load. If necessary, the
load current must be reduced by switching off individual loads!
