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.

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.

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.
