WARNING!
This UPS unit contains hazardous AC and DC voltages. Only qualified electricians should connect the UPS,
AC line and external batteries, 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.
As the UPS has no built-in disconnection devices to switch off external AC and DC input power, ensure that
disconnection devices are available as separate parts in connection with the installation!
The installer must provide each external disconnecting device for this UPS system with labels with the
following text:
“Isolate the Uninterruptible Power Supply (UPS) as instructed in this guide before working on circuit”
AC and/or DC voltage will always involve a potential risk of AC voltage at UPS output generated from either
batteries or utility. To avoid equipment damage or personal injury, always assume that there may be voltage
at UPS output.
This system is equipped with an auto-start function. If activated, the system may start without warning. Refer
to the “Programming” section for information on de-activation.
TEST BEFORE YOU TOUCH!
To reduce the risk of fire or electric shocks, 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, DC terminals or DC busbars 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 on batteries.
CAUTION!
This unit contains components sensitive to electrostatic discharge (ESD). If you do not follow the ESD
procedures, you may cause severe damage to electronic components.
