
As flammable gases (hydrogen) are released during battery charge and discharge, install
batteries in a place that has proper ventilation and is at least 1 meter away from heat and
ignition sources, such as switches and fuses.

When installing batteries, insulate metal tools by using insulation tape and remove metal
objects from hands.
 To prevent electric shocks, use insulation tools and wear electrostatic discharge (ESD)
gloves when installing and removing battery cables.

Keep the contact area between the copper bar and the battery output terminal clear and
connect them securely because a dirty contact area and insecure connection may cause
partial overtemperature, followed by potential fire accidents. When connecting individual
batteries in series by using tin-plated copper bar flat washers secured with stainless bolts,
tighten the bolts to a torque of at least 15 N· m.

When connecting batteries and uninterruptible power supplies (UPSs), switch the power
circuit breaker to off, check the voltages, and verify that battery terminals are connected to
the UPSs correctly.

To ensure good heat dissipation, keep a space of at least 10 mm between two adjacent
batteries.

When connecting multiple battery strings in parallel, connect cables for batteries in each
battery string in series and then install cables for the battery strings in parallel.

Before connecting battery strings and charging devices or loads, install cables for batteries
inside each battery string and check that the voltage of each battery string meets
requirements by using a multimeter.

When installing cables, tighten the battery terminal screws to a specified torque.
 If a battery is used for the first time, check that the capacity parameter in the power system
agrees with the capacity of the battery.
