accessories, and carefully read this manual and the user manual or installation instruction provided by the battery

manufacturer.

2. There shall be a clearance of 10mm between the vertical sides of the batteries for the smooth flow of the air

around the batteries.

3. Certain clearance shall be maintained between the battery top and the underside of the layer above it to facilitate

battery monitoring and maintenance.

4. The batteries shall be installed from the bottom layer upwards to avoid high gravity center. The battery shall be

properly installed and protected from vibration or shock.

5. Measure the battery voltage, and calibrate the battery voltage after UPS startup.

2.3.3 Battery Connection

1. When the battery cabinet is installed on a raised floor, the battery power cables and optional BCB control cables

can enter the UPS cabinet through the cabinet bottom. If the UPS and battery cabinet are installed side by side on a

solid floor, these cables can be led into the UPS cabinet through the cable entry holes on the lower part of the battery

cabinet.

2. When multiple battery strings are used, they shall be connected in series and then in parallel. Before applying load

and power-up, be sure to measure the total voltage of the battery strings and make sure that it is correct. The

negative and positive terminals of the battery must be connected to the corresponding negative and positive battery

terminals of the UPS according to the labels on the battery and UPS. Reverse battery connection may cause

explosion, fire, battery damage, UPS damage, and personal injury.

3. After connecting the battery cables, install an insulating shroud for each terminal.

4. When connecting the cables between the battery terminals and the BCB, connect from the BCB side first.

5. The bending radius of the cable shall be larger than 10D, where D is the outer diameter of the cable.

6. After cable connection, it is prohibited to pull the battery cables or the cable terminals.

7. Do not cross the battery cables during connection, and do not tie the battery cables together.

8. Refer to Figure 2-1 and Figure 2-2 for the battery cable connection.
