Warning: hazardous battery voltage present behind covers
1. No user-serviceable parts are located behind the protective covers that can only be removed by using tools. Only qualified service
personnel are authorized to remove such covers.
2. Before working on the copper bars connected to the external battery, please ensure they are disconnected from all power supplies.
Proper connection mode
Improper connection mode
Tighten the terminal bolt of the battery,
applying the specified torque
Applying too little or too much torque may result in poor connections. Under
certain conditions, the terminal may be subject to arcing or heat accumulation,
which can result in fire
3. Observe the following safety precautions when working on the batteries:
a) The batteries must be firmly and securely connected. After the connection is completed, the screw connections between all the
terminals and the batteries shall be calibrated. The torque requirements indicated in the specifications or user manual provided by the
battery manufacturer must be respected. The connections between all the wiring terminals and the batteries shall be inspected and
tightened at least once a year. Failure to do so may result in fire!
b) Visually inspect the batteries before accepting and/or using them. If the packaging is damaged, the terminals are dirty, eroded or
rusty, or if the cases are cracked, deformed or leaky, replace the battery with a new one. Failure to do so may result in reduced battery
capacity, leakage of electrolyte or even fires.
Battery damaged during handling or shipping
After a week of normal charge/discharge cycle testing
c) Batteries are very heavy. Please use the proper procedures when moving and lifting batteries in order to prevent injury and avoid
damaging battery terminals. Severe damage to the battery may cause fire.
d) The battery connecting terminal must not be subject to any force, such as pulling twisting forces exerted by the cables, otherwise,
the internal battery connections may be damaged. Severe damage to the battery may cause fire.
e) The battery must be installed and stored in a clean, cool and dry environment. Do not install the battery in a sealed battery chamber
or a sealed room. The battery room ventilation shall at least meet the requirement of EN50272-2001. Otherwise, battery bulging, fire or
even human injury may be caused.
f) Batteries must be installed away from heat sources (e.g. Transformers) and kept away from sources of fire, in addition, they must not
be burnt or heated in a fire. Otherwise, battery leakage, bulging, fire or explosion may be caused.
g) Do not connect conductors directly between the positive and negative terminals of the battery. Remove the rings, watches,
necklaces, bracelets and other metal items before working on batteries, and always used insulated tools (e.g. wrenches). Otherwise,
battery burning, human death/injury or explosion may be caused.
h) Do not attempt to disassemble, modify or demolish batteries. Otherwise, battery short circuit, liquid leakage or even human injury
