Page 52: Parallel Operation
GAMATRONIC, A S OLAR IVISION 6. P ARALLEL OPERATION 6.1 Theory When two or more Centric units are deployed in parallel, they are connected according to the decentralized static switch method (see below). Special technical solutions and control algorithms are implemented to synchronize all units in the system to prevent circulation of energy between them and to isolate a faulty unit from the common power bus. -
Page 53: Parallel Communication
When two or more Centric units are operated in parallel, parallel communication must take place between them in a "ring" arrangement. This is accomplished by the use of Gamatronic-provided cables with D-15 connectors on each end. Parallel communication keeps the parallel units synchronized with each nother, and is used to pass commands and status information between units. -
Page 54: Current Sharing
Connect the current-sharing terminals on UPS "Y" to those on UPS "Z". The parallel cable kit, supplied by Gamatronic, includes a prepared current sharing cable or cables.

Page 56: Epo And Parallel Operation
GAMATRONIC, A S OLAR IVISION The parallel UPSs must be connected to one another via their current sharing terminals (see Figure 25), using the current sharing cable supplied in the cable kit (see Figure 45). The kit includes cables for current sharing between two, three or four Centric units in parallel. -
Page 57: Instructions For Parallel Configuration
In the event that the customer desires to install two or more UPS systems in a parallel configuration: ● Gamatronic's prior approval of the details of the installation and configuration is required. Including approval of the parties participating in the commissioning and deployment of the UPS is required. -
Page 58: Table 7: Cable Sets For Parallel Configurations
GAMATRONIC, A S OLAR IVISION When reading this section, refer also to the appropriate connection diagram 1.The Centric units should be located near to one another. They must be connected to one another in a ring configuration using the parallel communication cables supplied in the cable kit. - Page 59 GAMATRONIC, A S OLAR IVISION Figure 47: Rear of the Centric, showing the Figure 48: Closeup of the master jumper PC3001 circuit board 4.Connect the UPSs in a ring configuration via the two 15-pin parallel communication terminals on each UPS. Use the supplied cables. See Figure 21, Figure 25 Figure 49: Parallel communication cable with 15-pin connectors Centric Installation Guide, rel.
- Page 60 GAMATRONIC, A S OLAR IVISION 5.Verify that each UPS’s output circuit breaker is in the OFF position (CB5 in the connection diagram). 6.Turn on one of the systems. This system will become the “master” system. Wait until the automatic startup procedure is complete – you will see the main menu screen. It should read “UPS ON, Normal mode”, and there should be no alarms present.
- Page 61 7.Put the UPS in multisystem mode: Main menu > Setup > System > Multisystem mode. (In the event that this option is blocked, consult Gamatronic Support or your distributor to obtain the needed password.) 8.Now turn on the other parallel system or systems. These will be the slave systems.
- Page 62 GAMATRONIC, A S OLAR IVISION For each module with an “out of range” output voltage, note which module it is, which phase or phases are out of range, and what the voltage is. The system must disconnceted from all others and the modules in the unit must be shut down.

Page 66: Shutting Down One Unit In A Parallel Configuration
GAMATRONIC, A S OLAR IVISION Warning: If using a shared battery, simply disconnecting the battery breakers to a single unit will not disconnect the dc voltage from the battery terminals. Dc voltage will be supplied for the other modules.

Page 70: Circuit Breaker Selectivity
See Table 3 for recommended circuit breaker ratings. In order to protect the UPS's bypass contactor and also the main input of the UPS, for all scenarios including short circuit, Gamatronic recommends the following: The circuit breaker that feeds the bypass input line and the circuit breaker feeding the main input of UPS shall have no magnetic protection delay, or a maximum magnetic protection delay of 50 msec. - Page 71 GAMATRONIC, A S OLAR IVISION This ensures that the circuit breaker will interrupt the short circuit before any damage can be done to the static switch contactor and the UPS modules. If you choose to use a time-delay circuit breaker on the bypass input line, recommended rating of the breaker is approximately six times the maximum bypass input current.

U SING THE WITH A GENERATOR 9.1 The Automatic Transfer Switch (ATS) At many sites a generator is used as a reserve source for feeding the UPS during mains power failure. In such cases, the switching between the two sources (the mains and the generator) is performed by an Automatic Transfer Switch (ATS). - Page 73 GAMATRONIC, A S OLAR IVISION Figure 58 is an example of the control panel of an ATS. The upper part of the control panel consists of a mimic diagram showing the control flow. “NS = 0” means the normal source is not available.
