• Only qualified service personnel (such as a licensed electrician) should perform the battery cabinet
installation. Risk of electrical shock.
• For the 120V/208V or 120V/240V wiring option the EBM AC input must be installed on its own dedicated
30 amp circuit. Do not connect the EBM AC input to the UPS.
• Before connecting an external battery cabinet to the UPS cabinet or to another external battery cabinet,
verify that all AC input power is removed from the UPS. Open the input service circuit breaker or turn the
external bypass switch to the SERVICE position. Observe all electrical safety precautions.
• Remove all battery modules in the UPS cabinet and/or battery cabinet to ensure DC voltage is removed
from the internal DC buses.
