2.3.2.2 Routine maintenance for batteries
Before installing batteries, read through the battery user manuals and pay attention to safety
precautions and connection methods provided by battery manufacture. When installing and
maintaining batteries, pay attention to the following points.
Before battery maintenance, get the tools, such as handles, insulated. Do not place other
objects on the top of batteries.
Wear protective goggles and take other necessary protective measures.
Before installing or maintaining batteries, wear rubber gloves and protective clothing to
prevent skin contact with electrolyte in the case of electrolyte overflow.
When moving batteries, avoid handling the battery upside down, handle batteries gently,
and pay attention to personal safety.
Keep the battery switch off when installing or maintaining the batteries.
Never use any organic solvent to clean batteries.
Never try to remove the safety valve or pour anything into batteries.
Never smoke or have an open flame around batteries.
Charge batteries in a timely manner after battery discharge.
Only professional personnel are allowed to perform maintenance.

5.2 Replacing Cooling System Components
5.2.1 Replacement Requirements
Before removing or installing the power cable, turn off the power switch.
Before connecting a power cable, check that the label on the power cable is correct.
During the installation of AC power supply facilities, follow the local safety regulations.
When operating the high-voltage and AC-powered facilities, use dedicated tools.
Ensure that a spare component is the same model as the faulty one is prepared before
replacing the faulty component.
Do not install or remove power cables when the device is on. Transient contact between
the core of the power cable and the conductor may generate electric arcs or sparks, which
may cause fire or hurt eyes.
Before removing cables from a faulty component, mark the cables with their
corresponding ports numbers for later connection (confirm by referring to the electrical
conceptual diagram).
Ensure that the cables are connected to the spare component properly.

The internal resistance can be measured only when the batteries are fully charged and no alarm is generated in the intelligent battery monitoring system. A measurement can be performed at least 45 minutes after the previous measurement ends. The battery internal resistance will change to an invalid value after power-off and then power-on again. By default, the BIM checks the battery internal resistance once every 24 hours as instructed by the CIM. The red indicator on the BIM is steady on during the check. You can also measure the battery internal resistance manually.
On the CIM WebUI home page, choose Monitoring > CIM System > Running Control, set Internal resistance, select the battery number from the range of 1–300, and click Submit to start measuring the battery internal resistance.
