11. ROUTINE INSPECTION
CAUTION
ELECTRIC SHOCK HAZARD
• Do not touch the energized surfaces of any electrical component in the battery
module system.
• Before servicing the battery module, follow all procedures to fully de-energize the
battery module system.
• Follow the “Safe Handling Procedures” (refer to Section 1.4, Safe Handling Procedures)
when working with the battery module.
Failure to follow these instructions may result in injury.
Periodically inspect the battery module:
1. Ensure that all DC cables are secure and fasteners are tight.
2. Ensure all Networking cables and connectors are secure and tight.
3. Ensure that the installation location is clean and free from debris.
4. Inspect for cracks in the battery module case.
5. Replace any damaged battery modules.
6. Replace any damaged cables.
12. STORAGE
Leaving the battery module connected to a trickle load or power electronics will
cause the battery module to discharge during storage. Without any load, the battery
module will self-discharge by approximately 3% per month while in storage. After
storage, charge the battery module to 100% SOC and perform at least one full
discharge and charge cycle before returning the battery module to service.
1. Store at 95% SOC or more. To store the battery module for up to 6 months, store
the battery module at 95% SOC or more. It must remain disconnected from all
loads and power electronics during storage.
2. Switch OFF the battery module. Set the battery module to OFF.
3. Check SOC every six months. Recharge the battery module to above 95% SOC
every six months.
4. Proper storage temperature. Ensure storage is within the temperatures specified
below.
• 1 Month storage temperature -30°C to 55°C (-22°F to 131°F)
• 6 Month storage temperature -10°C to 30°C (14°F to 86°F)
NOTICE
• Leaving the battery module connected to a load or power electronics during storage
may subject the battery module to discharge, resulting in irreversible damage and
voiding the warranty.
• Storing the battery module outside specified temperatures will result in irreversible
damage and void the warranty.
