INTRODUCTION
The Energy Storage Device ESD 201 is used
where a station battery source is not available
to provide circuit breaker trip power. The ESD
201 converts ac bus voltage to dc and stores
enough energy to trip the circuit breaker one
time for up to 72 hours after ac power has been
interrupted.
WARNING!
To prevent personal injury or equipment
damage, only qualified technicians or
operators should install, operate,
service this device.

ENERGY STORAGE DEVICE
Model: ESD 201
Part Number: 9 1106 00 101
HIGHLAND, IL 62249
THEORY OF OPERATION (Refer to the
Functional Block Diagram)
Power input to the ESD is 120 or 240 Vac.
This input is rectified and used to charge the
output capacitor (C1) to approximately 170 Vdc
for 120 ac input, 340 Vdc for 240 ac input. As
long as the ac input is applied, C1 continues to
be charged in this manner.
failure of the ac input is what the ESD 201 is
designed to protect against. Therefore, when
the ac fails, a battery powered oscillator circuit
and an associated step-up transformer act as
the C1 charging source. (The ESD 201 can be
or
interconnected to the system so that the
Oscillator circuits only function when the
breaker being controlled is closed.
Interconnection Diagram.) A Battery Charger
charges the battery as long as the ac input is
applied to the ESD 201.
HUMAN-MACHINE INTERFACE
The push button and LED indicator are used to
determine if the ESD 201 is operationally ready.
When the button is pushed, the LED will
illuminate if the capacitor has the minimum
charge of 180 Vdc required to trip the breaker.
The push button and LED do not indicate
whether or not the ac input is being applied.
NOTE
The test circuit acts as a discharge path to
the output capacitor. Therefore, the push
button should be depressed only long
enough to observe if the LED illuminates.
INSTALLATION
The device should be connected as shown in
the Interconnection Diagram. In order for the
ESD 201 internal battery operated capacitor
charging circuits to be operational, terminal 1
must be connected to terminal 4. This can be
accomplished by permanently jumping the two
terminals together.
however, the Oscillator Circuits will continually
be in operation if the battery is in place. This
will result in premature discharge of the battery
if ac input power is not being applied.
alternate (and preferable) approach involves
the use of the breaker auxiliary "a" contact.
The intent of the "a" contact is to inhibit
operation of the Oscillator Circuit (and thereby
eliminate battery drain) until the circuit breaker
is closed.
Each breaker should be provided with its own
ESD 201. The use of a single ESD 201 to
provide a tripping output for more than one
breaker (or other device) is not recommended.
Such configurations should only be considered
when it can be
independent testing, that combinations of
breakers (or devices) can be reliably operated
from a single ESD 201.

OPERATION
When the ESD 201 is properly interconnected
and after 120 or 240 Vac input power has been
applied, the unit is operationally ready. This
can be verified by using the push button as
described in the Human-Machine Interface
paragraph. No adjustments of any type should
However, the be necessary.
Ac power must be applied continually for a
minimum of 2 hours before the ESD 201 is
capable of developing full charge on the output
capacitor with a sustained interruption in ac
input.
If the batteries are fully discharged (terminal
voltage of 3.6 volts or less) it will take

approximately 48 hours to recharge the
batteries from the ac source.
situations, it is suggested that the battery be
removed and recharged with a high rate
charger (not to exceed a 0.1 ampere charging
rate). During this time, standard "AA" size cells
should be substituted in the ESD 201.
DISCHARGING
Since more than 400 Vdc can be present on the
ESD 201 output terminals, it is advisable to
discharge the storage capacitors if the unit is to
be worked on for any reason. The following
procedure can be used for discharging the
storage capacitor.
1. Obtain a 470 ohm, 5 watt wirewound
Using this approach
2. Connect a few inches of 14 AWG, 600 V,
3. Remove AC power input from terminals 1, 5

device require repairs, return it to the factory for

FIELD SERVICE AND ADJUSTMENT
The ESD 201 has been completely checked at
the factory. If for any reason the unit fails to
operate properly, it should be returned to the
factory for repair and/or replacement.
