IMPORTANT SAFETY WARNINGS

(SAVE THESE INSTRUCTIONS)

This manual contains important instructions regarding the installation and operation of this device.

Read this manual thoroughly before attempting to unpack, install or operate this device

CAUTION!

To prevent the risk of fire or electric shock, install in a temperature and humidity

controlled indoor area free of conductive contaminants. (Please see specifications for

acceptable temperature and humidity range.)

CAUTION! T o reduce the risk of electric shock, do not remove the cover except to service the

battery. No user serviceable parts are inside except the batter y.

CAUTION! Risk of explosion if battery is replaced by an incorrect type. Dispose of used batteries according to the instructions.

CAUTION! This unit must be wall mounted. Do not use the unit unless it is mounted correctly.

INTRODUCTION

The CS36A12V2 provides increased flexibility and cost effectiveness by separating the power supply unit (CA50A48V2) from the battery back up unit (CS36D12V). The power supply plugs into a 110/120Vac outlet. It converts the power to 48Vdc, which is then fed through a power cord to the battery back up unit.

The battery back up unit feeds 12Vdc to the ONT.

The UPS battery charges when it is connected to utility power. The battery charges fully during the first 24 hours of normal operation. Do not expect full battery run capability during this initial charge period.

Operation Guide

Start-Up: Plug the CA50A48V2 power supply into AC power. The unit is now ready to be placed into

service. The CS36D12V has four LED indicators and two control buttons. The table below

lists the functions of each.

Condition normal; AC power load, charges battery.

Battery is connected and in good condition.

48V input failure or loose connection between power supply and battery board; battery is supplying the power.

Every 45 days, the unit will automatically initiate a battery test. The test lasts 16 hours. if the battery needs to be replaced, an alarm signal will be sent to the Central Office.

Approximately 6 seconds after battery removal, the system initiates battery detection routine. Upon failure, an alarm signal will be sent.

When battery capacity is < 45% (approximately

12Vdc), unit signals low battery.

Battery Type

The battery is a standard sealed lead acid battery rated at 12Vdc / 7.2Ah. If required, the battery may be replaced with an approved 12Vdc / 7Ah battery.

Batteries are considered HAZARDOUS WASTE and must be disposed of properly.

Most retailers that sell batteries collect used batteries for recycling.

Auxiliary Power Connection (AUX)

Connection point for customer-supplied DC input voltage (12Vdc). At 45% remaining capacity, the

CS36D12V switches from internal battery to external source. The auxiliary power source supplies power to the load (ONT) in the event of 48V input voltage failure and a battery capacity of <45%.

Maintenance Mode

Maintenance mode determines remaining useful battery life. During the 16 hour test, the battery is discharge to determine its state. The unit measures the rate of change in the battery charge. If the rate of discharge is excessive, the battery replacement indicator is activated.

The CS36D12V enters the maintenance mode approximately once every 45 days.

In the event that the CS36D12V is in the maintenance mode and an AC failure occurs, maintenance

mode will cease and the CS36D12V will supply the power to the load.
