1. Important Safety Instructions 1.1 Important Information SAVE THESE INSTRUCTIONS – This manual contains important instructions that must be followed during the installation and maintenance of the UPS and batteries. • The UPS has its own external energy source (battery). A voltage may be present at the output terminals even when no AC input power is available. • This UPS is equipped with an EMI filter. To prevent potential leakage current hazard, ensure that the AC main supply is securely grounded.
• There is a risk of explosion if a battery is replaced by an incorrect type. • Do not dispose of batteries in a fire—the batteries may explode. Dispose of used batteries according to the battery manufacturer's instructions. • Do not open or mutilate batteries. Released electrolyte is harmful to the skin and eyes. It may be toxic. • This UPS supports electronic equipment in offices, telecommunications, process control, medical and security applications.
2. Introduction 2.1 General Characteristics • The UPS continuously supplies your critical device with stable, regulated, transient-free pure sine wave AC power. • High-efficiency 20 kHz pulse-width modulation (PWM) sine-wave topology yields an excellent overall performance. The output is capable of handling high crest factor and high inrush current loads. • A multi-functional LCD/LED panel displays the status of the UPS.
2.2 Optional Configurations The Continuity 6K / 10K UPS can be installed with a transformer—see Appendix A. It can also be installed in the parallel configuration—see Appendix B. 2.

A.5. Terminal Block Description for Input, Output A.5.1. 6K A.5.2.
A.5.3. Output Wiring Description The maximum output current for each terminal is 30A (6K) or 50A (10K). When the wiring of the TR OUTPUT block corresponds to drawing (a) and the input of L2-N2 from the UPS OUTPUT block is 200Vac, 220Vac, 230Vac or 240Vac, the output voltage is 100Vac, 110Vac, 115Vac or 240Vac. If the input of L2-N2 from UPS OUTPUT block is 208Vac, the output is 120Vac.
Appendix B Parallel System Installation The Continuity 6K and 10K can be connected in parallel to provide N+1 redundancy with up to 3 units in parallel plus one redundant. B.1. Important Safety Instructions • Parallel function of the UPS can only be enabled in the Normal mode operation. • Prior to a parallel installation, ensure the tolerance of the output voltage of each UPS at zero-load condition is less than 0.5Vac.
B.2.2. Selecting an Installation Position Air flow within the unit is from the front to back. Select an installation position that has good ventilation with at least 30 cm clearance around the equipment. Figure 1 Installation position B.2.3. Wiring Refer to the following table for cable and breaker sizes: Model 6KVA 10KVA Maximum Circuit Current Breaker AC input and Output 40A 33A 63A 54.
B.3. Installation Take the following steps to minimize EMI when wiring: 1. Make sure the input and output cables and the battery cables are kept separate from each other to avoid unnecessary noise interference. 2. Keep the path of the communication cables (RJ45, RS232, RS485, USB, EPO and Shutdown) separate from the I/O and battery cables. If unavoidable, place them at 90 degrees to each other and at least 20cm apart.
3. Arrange the power cables and the control signal cables as indicated in Figure 1 and Figure 2 depending on the UPS type. Ensure all the circuit breakers at input and output ends are set to OFF position. 4. A maintenance bypass box (MTBS) is recommended for use during maintenance. 5. Only two terminal resistors of the UPS in parallel are to be set to the ON position as indicated in Figure 4.
Set the two terminal resistors of two(2) or four(4) UPS to at "On" positions. ON OFF S1 Parallel Work Comm. Bus RS232 RS232 EPO ON T3 S1 Parallel Work Comm. Bus Not Intended to TNV Communication Network OUTPUT OFF Ext.

B.5. Maintenance Operation Procedure 1. Refer to the operations chapter to switch all UPS to Bypass supply mode. 2. Switch MTBS box to BYPASS position first. And then switch off all output breakers (CBo). Now the load is supplied through MTBS box from Bypass. 3. Make sure the UPS that needs maintenance is completely shutdown first. Then switch off the output breakers (CBo) and input breakers(CBi). 4. Proceed with maintenance. 5. Repeat the steps in section B.
