IMPORTANT SAFETY INSTRUCTIONS

SAVE THESE INSTRUCTIONS

This guide contains important instructions for your Silcon DP300E

UPS that should be followed during installation and maintenance of

the UPS and batteries.

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 APC’s toll free

technical support at: 1-877-287-7835 (1-877-2UPS-TEK).

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.

This UPS system has no built-in disconnecting devices for the external AC and DC

input power sources. Disconnecting devices must be provided as external parts in

connection with the installation!

The installer must provide each external disconnecting device for this UPS system

with labels having the following wording:

“Isolate the Uninterruptible Power Supply (UPS) as instructed in this guide before

working on the circuit”.

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.

This system is equipped with an auto-start function. If activated the system may start

without warning. Please refer to chapter 6: “Programming parameters” in this guide to

ensure de-activation.

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 dis-

charge (ESD). If you do not follow proper ESD procedures, you may

cause severe damage to electronic components.
