2 DESCRIPTION

2.1 SCB - SYNCHRONIZATION OF CRITICAL BUSES

Fig. 2.1-1 SCB – Synchronization of Critical Busses block diagram

The UPS configuration in Fig. 2.1-1 enhances security, reliability and safety of a system for the power
supply to extremely critical loads.

Basically it is composed of 4 major blocks, see Fig 2.1-1:

• UPS Group A: this group can be minimum 1, maximum 6 units.

• UPS Group B: this group can be minimum 1, maximum 6 units.

• ISM – Intelligent Synchronization Module.

ISM (Intelligent Synchronization Module) allows synchronizing of two independent groups of parallel
UPS’s, each having a maximum of 6 UPS units of equal rating from 10 – 500 kVA.

• STS – Static Transfer Switch.

A Static Transfer Switch can select between 2 sources (UPS groups).
As standard the Static Transfer Switch will supply the load from the preferred source.
In case the source would fail it will transfer the load to the second source.
A condition is that both sources are synchronized continuously, also on battery operation.

Each group of UPS’s are independent and capable to supply the full load, eventually redundant.
Each unit in the group is synchronized to its Master, which in return synchronizes to the utility voltage, if
available.

7 OPERATION

WARNING !

Before connecting hazardous voltages, make sure that:

• The cables for ISM supply and communication are correctly connected and in
accordance with existing standards;

• The equipment frame has been correctly grounded to the earth;

• All panels, which had been previously removed to allow ISM connection, have been

correctly reinstalled;

• Make sure fuse holders “F1, F2, F3, F4” inside the ISM cabinet and “F5, F6, F7, F8” in
the distribution cabinet(s) are closed.

7.1 PROCEDURES FOR SCB - SYNCHRONIZATION OF CRITICAL BUSSES

Procedure for SCB - Synchronization of Critical busses start-up

As soon as one of the UPS’s, either from Group A or Group B supplies the load, the ISM system will
automatically start-up.

NOTE !

As the ISM system starts-up, an Alarm is issued and the Buzzer starts sounding if the
synchronization at the last shutdown was disabled (“SYNC OFF”).

To enable synchronization, press either the key “SYNC AUTO” for automatic choice of the
synchronization source, or “SYNC MASTER A” / “SYNC MASTER B” to choose manually one of the two.
Condition for the above is that at least one UPS of a group has it’s electronics supplied and at least one
parallel group supplies the load, and consequently the ISM.

To switch from automatic to manual synchronization, press one of the keys marked “SYNC MASTER A”
or “SYNC MASTER B”, depending on which group is desired to be the Super Master.

To change from manual synchronization to automatic, press the key “SYNC AUTO”.

To disable synchronization press key “SYNC OFF”.

NOTE !

If a parallel system with an active synchronization command is shutdown (including
electronics), the command for synchronization will be disabled and the “Alarm 4005 ­Group failure on ISM system” is issued, together with an acoustical signal from the
buzzer.

Procedure for SCB - Synchronization of Critical busses shutdown

If no UPS of either Group A or B supplies the load, the ISM system is shutdown automatically.

8 MAINTENANCE

An ISM system, like other electrical equipment, needs periodic preventive maintenance.

A regular maintenance check of your installation guarantees higher reliability of your ISM.

Preventive maintenance work on the ISM can be done only by trained Service Technicians.

We therefore recommend you sign a Maintenance and Service contract with the local Service Centre
organisation.

The ISM follows the same service program and intervals as for UPS systems.

Service check

If this LED lights up during the normal operation, that means that the unit has not been serviced for the
last 20’000 hours by a GE Trained Technician.

We highly recommend that you contact your Service Centre for preventive maintenance work.

ISM room conditions and temperature

The ISM room has to be maintained clean and free from dust.

A high temperature of the ISM room affects the lifetime of several components inside the equipment.

Component with limited lifetime

We recommend the replacement of component such as lithium battery for the backup of data on the
control boards of the units every 50’000 hours.
