6.2 EXCHANGE OF UNITS
a)
Exchange of an inverter
In this case, the manual by-pass switch does not need to be used.
However, if this is desired for any reason, the manual by-pass switch must
be switched to position 1 (Load on By-pass Input).
Removal of the inverter:
Switch the inverter off using the unit switch (in case the
remaining inverters in the system cannot take over the load, the
connected load will be transferred to the mains supply via the
SBS units).
Remove the four retaining screws
Pull the unit out of the front of the cabinet
(Attention
! See warning statement in paragraph 4.4.2)
Insertion of the inverter:
The inverter must be switched off!
The circuit breaker (F1) on rear of unit must be switched on!
Slide the inverter into the inverter shelf until the unit is flush with
the frame of the cabinet.

If necessary, turn the manual by-pass switch to position 0 (UPS
operation).

Warning!
The manual by-pass switch must be used in this case
otherwise there will be an interruption in the power supply
to the load equipment. It must be established beforehand,
which of the scenarios described in Chapter 6.1 is valid
(check the state of the SBS and the operation mode!)
