User’s Manual
for CS36A12V2
Bundled Kit
(CA50A48V2 + CS36D12V)
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.

CS36D12V Battery Replacement
c
Batteries are considered HAZARDOUS WASTE and must be disposed of properly.
Most retailers that sell batteries collect used batteries for recycling.
Fig.2
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.
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.
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.
Step 1:
a. Press battery cover catch (A) and slide the cover to the left
    to remove.
b. Remove the battery connector (see Fig.2).
c. Remove the battery strain release latch to remove battery.
Step 2:
a. Replace battery cable on the new battery.
b. Place the new battery into battery compartment.
c. Close the battery cover.
This equipment has been tested and found to comply with the limit for a Class B digital device, pursuant to part 15 of the FCC Rules. These limits are designed to provide protection against
