4.1.4 Dual and Single Utility Supply

WARNING!

UPS units contain hazardous AC and DC voltages. Only qualified electricians should install 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 provided as separate parts in connection with the installation!

The installer must provide each external disconnecting device for this UPS system with labels with wording as follows:

“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 “Programming Parameters” 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 or 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 with working near batteries.

CAUTION!

This unit contains components sensitive to electrostatic discharge (ESD). If you do not follow the ESD procedures, you may cause severe dammage to electronic components.

The UPS is fitted with dual utility input as standard. If dual utility is not available or not needed, a small modification has to be made. See section 4.1.5 switching from dual to single utility input.
