IMPORTANT NOTE: Parallel system installation is much more complex from stand alone UPS installation, it needs qualified service personnel. You have to keep 80 cm distance between two UPS’s for service purposes. Add 20% tolerance to cable sizes, fuses and circuit breakers in parallel connection. In figure 3-2 ,the connections of 2 parallel UPS’s and load distribution panel are shown.
IV. OPERATING INSTRUCTIONS NOTE: In the surroundings of 30 meters radio appliances and radio broadcasting my be disturbed. The surrounding must be observed against radio interferrences. In case the manufacturer has to support suitable modifications. 4.1 Introduction The Operating instructions will be considered in two parts: 1.
4.2.2 Procedure For Switching The UPS Into a Maintenance Bypass From Normal Operation : This procedure should be followed when turning from normal operation to maintenance bypass. This procedure can be used for supplying temporary mains voltage to the system during the maintenance of the UPS or in case of failure.
4.2.5 Procedure For Completely Powering Down The UPS : TURNING OFF THE UPS All the power switches, isolators and circuit breakers should be turned off, with the following sequence. (Turn off into “0” (OFF) position). There will be no voltage on the load. WARNING!!! This procedure will cut the energy of all the equipments, which are connected to UPS output.
OPERATION MODES: • ON-LINE • PARALLEL • HOT-STANDBY • REDUNDANT 5. After selecting one of the above modes, press “ENTER” until the beep sound stops. 6. Turn off S1 (inverter input) and after a few seconds, turn it on again. Now the inverter is ready to operate in the selected mode.
4.3.3 Procedure For Switching The UPS-ON For Normal Operation From a Maintenance By-Pass Power Down Condition : With the S6 switches (static bypass) of the inverters (at least one of them) in “STATIC BYPASS” position, turn on the parallel connected UPS’s UPS1 and UPS2 as follows: 1) Turn on the S2 switches (static bypass) of both UPS’s.
V. INSTALLATION PROCEDURE 5.1 Introduction WARNING!!! • Do not apply electrical power to the UPS equipment before the arrival of authorized service personnel. • The UPS equipment should be installed by a qualified service personnel. • The connection of the batteries and the maintenance should be done by the qualified service personnel. •...
5.4 Connecting The UPS Power Cables CAUTION! Only qualified personnel should install or service UPS / batteries. The ac input to the UPS should be supplied by a separate line from the ac distribution board. The input/output cables can be sized to suit the modules rating according to the table below. The connections of the electric panel should be supplied by grounded outlet.
