Anderson PP45 connectors for user external battery cabinet.

1.3 Maintenance, servicing and faults

The UPS operates with hazardous voltages. Repairs may be carried out
only by qualified maintenance personnel.
CAUTION - risk of electric shock: Even after the unit is disconnected from
the mains power supply (building wiring socket), components inside the
UPS are still connected to the battery and are potentially dangerous.
Before carrying out any kind of service and/or maintenance, disconnect
the batteries. Verify that no current is present and no hazardous voltage
exists in the capacitor or BUS capacitor terminals.
CAUTION - risk of electric shock: The battery circuit is not isolated from
the input voltage. Hazardous voltages may occur between the battery
terminals and the ground. Verify that no voltage is present before
servicing!
Batteries must be replaced only by qualified personnel in compliance with
the directions given in paragraph 1.3.3.
Please replace the fuse only by a fuse of the same type and of the same
amperage in order to avoid fire hazards.
Do not dismantle the UPS, unless you are qualified maintenance
personnel.
1.3.1 UPS and Battery Care
For best preventive maintenance results, keep the area around the UPS clean
and dust-free. If the atmosphere is very dusty, clean the outside of the system
with a vacuum cleaner. For long battery life, keep the UPS in an ambient
temperature of 25°C (77°F)
1.3.2 Storing the UPS and Batteries
When the UPS is intended to be stored for a long period, recharge the battery
every 6 months by connecting the UPS to utility power. The batteries charge
to 90% capacity in approximately 4 hours. However, it is recommended that
the batteries charge for 48 hours after long-term storage.
