Battery boxes should be stored in a cool place with the protective cover on. Hot and humid place will cause
damage to Battery boxes.
2.2.2 Traditional Battery Installation
Only the qualified engineers are allowed to install and maintain mounted in a traditional battery cabinet or
shelf. To ensure safety, install the external battery in a locked cabinet or dedicated battery room accessible
just to service qualified personnel.
A minimum space of 10mm must be reserved on all vertical sides of the battery block to permit free air
movement around the cells.
A certain clearance should be reserved between the top of the cells and the underside of the shelf above as
this is necessary for monitoring and servicing the cells.
When installing the batteries always work from the bottom shelf upwards to prevent raising the center of gravity.
Install the batteries reliably and avoid vibration and mechanical bumping.
The bending radius of cable should be more than 10D, where "D" is the outer diameter of cable.
When connect the cable, do not cross the battery cables and do not bind the battery cables together. The
battery connection must be firm and reliable. After the connection, all the connections between the wiring
terminals and the batteries must be corrected to meet the torque requirement provided in the specifications
and user manuals of the battery manufacturers.
Each battery terminal should be insulated after its connection has been made.
Check if the battery is unexpectedly grounded. If the battery is unexpectedly grounded, remove the earth
power supply. Contacting any part of the grounded earth may be subject to electric shock.
Measure the battery voltage, and carry out battery voltage calibration after the UPS is started.
Please note that number of cells set via software must be consistent with the actual number of cells.
