Safety Warnings

CAUTION: Before performing the procedures in this document, read and follow the safety instructions and important regulatory information in your Safety, Environmental, and Regulatory Information document.

IMPORTANT SAFETY INSTRUCTIONS

SAVE THESE INSTRUCTIONS

This manual contains important instructions that you should follow during installation and maintenance of the UPS and batteries. Please read all instructions before operating the equipment and save this manual for future reference.

DANGER: Observe the following instruction to help prevent an imminently hazardous situation which, if not avoided, will result in death or serious injury:

SThis UPS contains LETHAL VOLTAGES. All repairs and service should be performed by AUTHORIZED SERVICE PERSONNEL ONLY. There are NO USER SERVICEABLE PARTS inside the UPS.

WARNING: Observe the following instructions to help prevent a potentially hazardous situation which, if not avoided, could result in death or injury:

SOnly qualified service personnel (such as a licensed electrician) shall perform the electrical installation. Risk of electrical shock.

SFor UPS models with hardwired input, overcurrent protection for the output AC circuit(s) is to be provided by others.

SFor UPS models with hardwired input, suitably rated disconnect switches for the output AC circuit(s) are to be provided by others.

SOutput overcurrent protection and disconnect switch must be provided by others.

SThis UPS contains its own energy source (batteries). The output receptacles may carry live voltage even when the UPS is not connected to an AC supply.

SDo not remove or unplug the input cord when the UPS is turned on. This removes the safety ground from the UPS and the equipment connected to the UPS.

STo reduce the risk of fire, connect only to a circuit provided with branch circuit overcurrent protection with an ampere rating in accordance with the National Electrical Code® (NEC®), ANSI/NFPA 70 or your local electrical code:
