Removal of the SBS:
After the manual by-pass switch has been turned to position 1 or 2, the 4
retaining screws are removed and the SBS is pulled out of the front of the
cabinet. This simultaneously removes the operating element of the manual
by-pass switch from its mounting shaft. The manual bypass switch is
mechanically fastened to the SBS.
Insertion of the SBS:
If not already done, the By-pass handle assembly must be mounted onto
the new SBS. Before the SBS is replaced into the cabinet, the operating
element of the manual by-pass switch must be turned to position 1 or 2,
according to the position of the switch before the SBS was removed. The
SBS is pushed into the free slot until the unit is flush with the frame of the
cabinet. The four retaining screws are screwed back in.
Finally, the manual by-pass switch must be turned back to position 0 (UPS
operation).
6.3 UPGRADING THE SYSTEM
The inverter system can be equipped with a maximum of 5 inverters.
Additional inverters can only be added to the system if there are free
inverter shelves. The system can be upgraded during running operations
without the need to switch off other components or the need to switch the
manual by-pass switch.
The dummy plates covering the free inverter shelves are removed. The
circuit breaker F1 located on the rear of the inverter module (Refer to Fig.
8) is switched on and the ON/OFF switch (Item 3, Fig. 7) is switched off.
The new inverter is pushed into the slot, fixed with the 4 retaining screws
and then switched on. After the start-up phase, the inverter is brought
into parallel operation and the current then is evenly distributed to all
inverters that are switched on.
7 DESCRIPTION OF FUNCTION
It is not necessary to understand the exact function of all components in
this inverter system. However, basic knowledge of essential components
aids in the understanding of the whole system and helps to avoid errors in
the maintenance and operation.
