Page 8: The Operating Modes Of Ups
MECHANIC TRANSFER SWITCH (MAINTENANCE BY-PASS): A second, manually controlled, ”maintenance by-pass” supply is also incorporated into the UPS design. Its purpose is to enable the critical load to be powered from the mains (by-pass) supply while the UPS is shut down for maintenance or troubleshooting. The load is unprotected against mains power supply aberrations or failure when it is connected to either the static by-pass or maintenance by-pass supply. - Page 9 Mechanic transfer switch Maintenance Bypass Static Transfer Switch 3 Phase By-Pass Static By-Pass Supply Input 3 phase 3 Phase load Line output Input Inverter 12 pulse Rectifier Battery group Figure 1.2 UPS Split (external) By-Pass Block Diagram...

Page 21: Parallel Operation
III. PARALLEL OPERATION 3.1 Introduction Two of T-300P UPS can be used in parallel mode, the purpose of parallel use: • Increasing security • Redundancy • Power increment purpose 3.1.1 Security At stand alone UPS systems mains voltage is spare energy in case of UPS failure, but some critical loads don’t works with mains tolerances. -
Page 22: Redundant Parallel Mode
The general diagram of parallel connection is shown below : UPS1 BATT.1 AC/DC -1 INVERTER 1 OUTPUT UPS2 BATT.2 AC/DC -2 INVERTER 2 Figure 3-1 Parallel connected UPS The inputs of two UPS is connected to mains, outputs of two UPS is connected to each other there is two battery group. -
Page 23: Hot Standby Mode
3.2.3 Hot Standby Mode If current sharing is active two UPS is operating continuesly and lifetime of some parts will be shorten. Hot standby mode is solution for UPS lifetime. In this mode UPS 1 feeds the load and the UPS 2 waits spare there is no current it is in standby mode but it is ready to work. - Page 24 IMPORTANT NOTE: Parallel system installation is much more complex from stand alone UPS installation, it needs qualified sevice personnel. You have to keep 80 cm distance between two UPS for service purposes. The maximum length of digital and analog cable is 2 meters. Add %20 tolerant to cables, fuses and circuit breakers in parallel connection.

Page 25: Operating Instructions
IV. OPERATING INSTRUCTIONS 4.1 Introduction UPS can operate in one of the following operating modes: a) Normal Operation : All the circuit breakers (except the maintenance by-pass switch) are turned on (“1” position) and load is connected to the UPS. b) Maintenance By-Pass Operation : Ups is not in use because of maintenance purposes. -
Page 26: Procedure For Switching The Ups Into A Maintenance Bypass From Normal Operation
4.3 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 in giving temporary mains voltage to the system during the maintenance of the UPS or in case of failure. -
Page 27: Procedure For Switching The Ups On From Static By-Pass
Procedure For Switching The UPS ON From Static By-Pass Press on the UP or DOWN button until there is “COMMAND MENU” message on the front panel of the UPS. Then press “ENTER” button. Press on the UP or DOWN button when there is “ENTER <INVERTER>” message on the front panel of the UPS. -

Page 29: Connecting The Ups Power Cables
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. -
Page 30: Safety Earth
NOTES: The neutral conductor should be sized for 1,5 times the output/bypass phase current. The Earth conductor should be sized at 2 times the output/bypass conductor (this is dependent on the fault rating, cable lengths, type of protection etc.) These recommendations are for guideline purposes only and are superceded by local regulations and codes of practice. - Page 31 NORMAL CONNECTIONS SPLIT BY-PASS CONNECTIONS Figure 5-2 250-300 kVA UPS Power Connections...
