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 damage, 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.

INSTALLATION
Warning!
Perform the discharging procedure before
handling the ESD202.
Connections
Typical ESD202 connections are shown in Figure 2.
ESD202 terminals accommodate a maximum wire
size of 12 AWG (3.31 mm
2
). The terminal screws have
a maximum torque rating of 9 in-lb (1 Nm).
STORAGE AND MAINTENANCE
An ESD202 should be used with a single circuit
breaker. Control of more than one breaker (or other
devices) by a single ESD202 is not recommended. If
control of more than one breaker is desired, it must be
demonstrated, through independent testing, that
combinations of breakers (or other devices) can be
reliably operated from a single ESD202.
Mounting
ESD202 mounting dimensions are illustrated in Figure
1. Dimensions are given in inches with millimeters in
parenthesis.
This device contains long-life, aluminum electrolytic
capacitors. For devices that are not in service (spares
in storage), the life of these capacitors can be
maximized by energizing the device for 30 minutes
once per year.
No maintenance of the ESD202 is required other than
periodically checking that all connections are clean
and tight. The ESD202 is not field repairable. If repairs
are required, return the ESD202 to Basler Electric.
