(Optional) Installing Batteries
Smoking and sparks are prohibited near batteries.
Switch off battery circuit breakers before installing batteries.
Comply with regulations and warnings of the battery manufacturer.
Use tools with insulated handles, otherwise, batteries may be burnt out and personal injury
may occur.
During battery operations, wear goggles, rubber gloves, and protective clothes. Remove
conductive articles such as watches, bracelets, and rings.
If battery acid gets in the eyes, rinse with cold water for more than 15 minutes and seek
media advice immediately. If battery acid contacts skin or clothing, wash with soap and
water immediately.
Do not use metal to simultaneously contact two or more battery terminals. Do not use
metal to simultaneously touch battery terminals and grounded objects (for example,
battery compartment); otherwise, transient short circuit occurs, which produces sparks or
explosion.
During battery installation, never short-circuit or reversely connect positive and negative
battery terminals. Connect the negative battery cable before the positive battery cable.
Secure battery cables to a torque specified in battery documentation. Loose connections
will result in excessive voltage drop or cause batteries to burn out when the current is
large.
The following describes how to install the first layer of battery. All batteries are installed in
the same manner.
When one battery string connects to the system, connect the battery string to battery string
position 1. Otherwise, battery currents may not be detected.
