Thank You!

Thank you for chosing an APC Silcon UPS. Please read this Installation Guide thoroughly prior to

installing the system. It provides important information on safe and efficient installation.

The installation and use of this product must comply with national, federal, state, municipal and

local codes.

Safety Symbols used in this manual

WARNING!

Indicates a hazard which, if not avoided, could result in injury or death.

CAUTION!

Indicates a hazard which, if not avoided, could result in damage to

the product or other property.

NOTICE!

Read and pay attention to this important information.

WARNING!

This UPS unit contains hazardous AC and DC voltages. Only qualified electricians should install 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 provided 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 “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 or DC terminals, 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.

PLEASE RECYCLE

The shipping materials for the APC Silcon UPS are recyclable. Please save for later use or dispose of

them appropriately.

4.1.4 Dual and Single Utility Supply

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.

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.
