2.3 Installation

2.3.1 Important Note

1. Please position the UPS on the flat ground/surface ..

2. The distance from the rear and side panels of the UPS to the wall or other equipment should be greater than 20cm, and the air inlets on the front panel and at the bottom of the UPS should be kept unobstructed to facilitate ventilation and heat dissipation.

3. Please ensure that the UPS is installed in an environment in compliance with UPS environmental specification.

4. Avoid using the UPS in dusty or corrosive environment.

It can be included in monitoring system defined by users .

Used for heat dissipation and ventilation of UPS

5. Even if the UPS is shutdown, there could be high voltage inside, untrained personnel must not open the UPS as there may be danger of electric shock.

6. Install four-pole or three-pole interactive circuit breaker with capacity higher than

80A(suitable for 10kVA system）or 125A（ for 15kVA/20kVA system）on the hot line

of Three-phase utility input to isolate the input source in case of emergency. When using three-pole interactive circuit breaker, utility neutral line need not go through the circuit breaker and can be connected with UPS' neutral line directly.

7. Please use right cable connection method to ensure the safety of UPS or customer equipment::

1. Prior to any wire connection, please confirm that all the input and output circuit breakers are in “OFF”state;

2. As shown in Figure 2-6, connect the input cables（three hot lines, neutral line and

earth line）to the correspondent terminals and secure the screw;



Note

Please do not reverse connection of the input hot line and neutral line！

Because the input default configuration of system's U phase is bypass input, please ensure the proper connection of U phase.

Please don't use the power source socket on the wall as the UPS' input source.

3. Connect the input cables （hot lines, neutral line and earth line）of user's equipment

to the correspondent UPS output terminals refer , figure 2-6 .



Note

When connecting the input and output cables, the input hot line and neutral line must be connected correctly and the UPS must be connected to earth firmly.
