DANGER!
POTENTIALLY LETHAL HIGH VOLTAGE! FOR QUALIFIED ELECTRICIANS ONLY!
Follow all safety precautions in the Safety section before adding or replacing internal batteries.
DANGER!
DO NOT REMOVE BATTERY SLEEVE!
Do not remove the plastic sleeve covering the battery strings. The sleeve is designed to prevent accidental contact
with the terminals on the individual batteries. Contact with the terminals will create a potential for serious injury or
death from lethal high voltage. Do not allow tools or other metal objects to come in contact with the terminals.
CAUTION!
BATTERY PACKS ARE HEAVY!
Use assistants as needed.
WARNING!
CHECK BATTERY PACK VOLTAGE BEFORE COMPLETING INSTALLATION
Do not install battery packs with DC voltages outside the acceptable range. (They may compromise battery backup
capabilities).
NOTE!
Each battery pack consists of two strings of batteries: one string with a BLACK cable and one string with a RED cable.
Thebatteriesaredesignedforhot-swapreplacement,whichallowsconnectedequipmenttocontinuallyreceiveACmainspower(butnotbatterybackup
