Model ESD202
Part Number 9290500100
INTRODUCTION
The ESD202 Energy Storage Device supplies power
to trip a circuit breaker when the station battery source
is not available. The ESD202 stores sufficient energy
to supply circuit breaker tripping power for 12 seconds
following a loss of station power.
Warning!
Lethal voltage may be present at terminals
after power is removed.
To prevent personal injury or equipment dam-
age, only qualified technicians or operators
should install, operate, and service this
device.

FUNCTIONAL DESCRIPTION
AC power applied to the ESD202 is rectified and used
to charge internal capacitors to approximately
340 Vdc. The capacitors will retain a charge of at least
9.1 joules (at 191 Vdc) for at least 12 seconds after a
loss of ac input power.
A light emitting diode (LED), located at the rear of the
device, lights when the capacitors are charged and
the ESD202 is ready for operation. The LED lights
when a minimum charge of 5.6 joules at 150 Vdc is
available at the ESD202 output. A lighted LED does
not verify application of input power to the ESD202.
DISCHARGING THE ESD202
Over 300 Vdc may be present on the output terminals
even though all input power is removed from the
ESD202. The capacitors within the ESD202 should be
discharged before working with the device. Perform
the following steps to discharge the EDS 202 output.
1. Obtain a 470 ohm, 5 watt, wire-wound resistor
and connect a length of 14 AWG, 600 V, insulated
wire to each end of the resistor.
2. Remove the ac power applied at terminals 1 and 4
of the ESD202.
3. Carefully touch one wire to terminal 3 and the
other wire to terminal 4. Hold the wires on the
terminals for at least 5 seconds.
4. Verify that the ESD202 output is discharged by
measuring the output (terminals 3 (+) and 4 (–))
with a dc voltmeter.
