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

). The terminal screws have

a maximum torque rating of 9 in-lb (1 Nm).

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.
