Installing Batteries
Battery installation should always be treated like a brand new installation.
This means, that all safety and precautionary guidelines that were followed
prior and during the installation of the battery charger, must again be
followed in order to avoid risks of electrical shock, injury, or death.
To replace an old battery:
1. Turn off the AC source by disconnecting the AC line and/or opening
the AC source disconnect.
2. Switch off all devices operating from currently installed batteries.
3. Disconnect the battery cables from the old battery.
NOTE: For Negative chassis systems, disconnect the negative cable
first, then the positive cable.
For Positive chassis systems, disconnect the positive cable first, then
the negative cable.
Inspect all AC and DC cables for damage and repair, if necessary.
4. Replace the old battery with the new battery.
5. Reconnect the battery cables to the new battery.
NOTE: For Negative chassis systems, reconnect the positive cable first,
then the negative cable.
For Positive chassis systems, reconnect the negative cable first, then
the positive cable.
Input Voltage Operating and Derating
When AC input is within the lower range between 90–108 Vac, the
Truecharge2 Battery Charger derates to 80% of maximum current.
However, when AC input increases above 108 Vac up to 265 Vac,
maximum current returns to 100% capacity. Furthermore, the Truecharge2
Battery Charger will continue to operate at 100% of maximum current.
ELECTRICAL SHOCK HAZARD
Disconnect both AC and DC power from the battery charger before
attempting before replacing old or defective batteries and even installing
new batteries.
Failure to follow these instructions will result in death or serious
injury.
IMPORTANT:
If the new battery is different from the old one in chemistry,
temperature, or size, remember to re-configure the battery settings
accordingly. See “Setting the Battery Temperature without a BTS” on page
32 and “Configuring the Battery Bank Type” on page 34.
