IMPORTANT SAFETY INSTRUCTIONS
SAVE THESE INSTRUCTIONS
This manual contains important instructions for your
UNITY
/I™ UPS.
The installation and use of this product must comply with all national, federal, state, municipal,
or local codes that apply. If you need help, please call BEST’s Technical Support Center at
1-800-356-5737 (U.S.A. or Canada; elsewhere, call your local BEST office).
WARNING!
UPS units contain hazardous AC and DC voltages. A qualified electrician must install the
UPS, AC line service, and external batteries according to local and national codes and must
be familiar with batteries and battery installation.
Before installing, maintaining, or servicing the UPS, shut off the UPS and disconnect all
sources of AC and DC power.
Whenever AC and/or DC voltage is applied, there may be AC voltage at the UPS output;
this is true because the UPS can supply output power from mains or from its batteries. To
avoid equipment damage or personal injury, always assume that there may be voltage at the
UPS output.
TEST BEFORE TOUCHING!
To reduce the risk of fire or electric shock, install the UPS and external batteries in a
temperature and humidity controlled indoor area, free of conductive contaminants.
UPS batteries are high current sources. Shorting battery terminals or DC terminal strips can
cause severe arcing, equipment damage and injury. A short circuit can cause a battery to
explode. Always wear protective clothing and eye protection and use insulated tools when
working near batteries.
This unit contains components that are sensitive to electrostatic discharge (ESD).
If you do not follow proper ESD procedures, you may cause severe damage to
electronic components.
