User Safety

 

WARNING!

 

This UPS 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!

 

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.

 

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”

 

WARNING!

 

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.

 

WARNING!

 

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

Caution

follow the ESD procedures, you may cause severe damage to electronic components.
