Thank You

Thank you for chosing APC Silcon. Please read this User Guide thoroughly prior to installing the system as it provides important information on safe and efficient installation and use.

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 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-indisconnection 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-startfunction. If activated, the system may start without warning. Refer to the “Programming” section for information onde-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-currentsources. 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.

PLEASE RECYCLE

The shipping materials are recyclable. Please save for later use or dispose of them appropriately.

Introduction

1.0 Introduction

This UPS system is designed to offer reliable and problem-freepower supply for several years. The system requires only a minimum of maintenance, but we recommend you follow the maintenance guidelines described in section 6.0 Maintenance & Testing.

1.1Display Unit

The display unit (located on the front of the UPS) is the link between the user and the UPS and consists of a display, an alarm LED indicator and a keyboard. The display reads parameters, measured values and alarm messages. Alarms and the pressing of keys will activate a back light which is set to switch off automatically after 5 minutes of inactivity.

By pressing andsimultaneously you increase the back light contrast. The pressing of

andsimultaneously decreases the contrast.

The LED alarm is linked to an acoustic signal indicating incorrect operation. Alarms will change the LED light from green to red. Use keyboard to program operating parameters and to display parameters / alarm messages.

WARNING!

AC voltage generated either from batteries or utility may be present at UPS output.

Always disconnect AC input supply source, switch off UPS, AND switch off DC.

TEST BEFORE YOU TOUCH!

Some UPS systems have a factory-setautostart feature, automatically switching on UPS whenever utility supply is switched on (AC line). See section 4.0 Parameter settings for instructions on how to switch off this function.

Only qualified electricians should start up or shut down APC Silcon UPS systems and instructions in the Installation Guide should be followed. Prior to being serviced, the APC Silcon UPS must be left in shut-downmode for a minimum of 5 minutes.

CAUTION!

Refer to the Maintenance & Testing section in this guide if the UPS is to be taken out of operation for more than 48 hours.

Users without electrical qualifications may switch UPS to and from stand-by-mode/normaloperation, following instructions below. (In stand-by mode, the UPS has no output voltage).

2.1Stop UPS (for stand-by)

CAUTION!

If the UPS system is equipped with a service bypass panel, and if the load must remain energized by utility, refer to the Operating Service Bypass Panel sections in this guide before proceeding

WARNING!

TEST BEFORE YOU TOUCH!

A special design feature switches the system into bypass operation in the event of internal power supply failure or controller circuit failure to ensure uninterrupted output voltage.

Because of this special feature, the UPS may contain output voltage even when it is switched off.

1.Open front doors

2.Note that step 3 will interrupt output voltage and activate the alarm! The red LED alarm below the display will light up

The acoustic alarm will sound for 30 seconds*

Stop/Start UPS and Operating the External Service Bypass

The UPS is now isolated. Maintenance/repair, disconnection or removal can now be carried out.

CAUTION!

Recharge batteries out of service every 3 months to prevent damage.

WARNING!

Internal DC capacitor may contain energy even after the UPS has been switched off. Allow for automatic discharge by waiting at least 5 minutes after switching off UPS and battery breakers before working on the UPS.

2.4Start UPS (from complete power down)

2.4.1 UPS start-up

CAUTION!

Make sure all cable connections are in place prior to first start-up.

NOTICE!

After first system start-up,check that battery temperature is displayable (pressandsimultaneously on the display – it reads NV (not valid) if incorrectly installed). A battery capacity test is recommended after the electric installation.

NOTICE!

If for any reason the start-upprocedure is interrupted, wait for the display to show the step 4 message: “Stop charge DC capacitors : YES” and repeat procedure from there.

CAUTION!

Do not close the MCCBs in the Battery Breaker Box unless the display reads: “Insert fuse or close MCCB” – otherwise the UPS may be damaged. If the display reads “DC capacitor charge error”, do not close MCCB.

Call for assistance.

WARNING!

If “Autostart” is active the UPS will start automatically after step 9 (with a 1-minutedelay)
