Chapter 1 Product Overview

1.1 Foreword

Thank you for using this product, this meter interface installation manual provides

information on the AEM-DRB meter. The AEM-DRB multi-function control smart meter is used

for power distribution (electric power system) monitoring and control in various industries.

Suitable for measuring CAT II power system.

Before using, please carefully read this manual to ensure that it is used correctly. The

following matters must be observed before you have read this manual:

• The installation environment must be free of moisture, corrosive gases and flammable

gases.

• When wiring, please follow the wiring diagram to explain the construction.

• The grounding project must be implemented, and the grounding must be carried out in

accordance with the current state.

• Do not dismantle the meter or change the wiring while power is on.

• Do not touch the power supply during power-on operation to avoid electric shock.

• If you still have problems using it, please contact your dealer or our customer service

center. Due to the constant improvement of the product, please contact your dealer or

the website (http://www.adtek.com.tw) to download the latest version when the content

specifications are corrected.

1.2 Outward & Instructions

The AEM-DRB has a liquid crystal display screen that displays five measurement data

per page

1.3 Warning & Criterion

• Installation attention

• Wiring attention

• Operation attention

• Beware of potential hazards. Wear safety equipment properly

when operating this device and follow safety standards and related

regulations for operating electric equipment.

• Installation of this device should be performed by licensed

professionals. Perform operations only after carefully reading this

manual.

• Operate this device according to this manual to prevent improper

operation that may cause damage and bodily harm.

• This device should be installed in a properly-insulated fire-

protection cabinet.

• When using the equipment, potential transformer for secondary

side is prohibited short circuit.

• When using the equipment, current transformer must not be under

an open circuitaa.

• When using the equipment, please make sure current transformer

for secondary side has been locked on the equipment. To avoid the

main trunk line falling off during use, causing equipment damage.

• When used with a current transformer (CT), please use a current

transformer (CT) that meets UL2808 in the United States/Canada,

and use a current transformer (CT) that meets the requirements of

IEC61869-2 or AHJ in other countries to ensure use Safety.

• Do not operate alone.

• Power should be disconnected before installing, checking, or

maintaining this device.

• You must use a voltage checking device with the correct rated

values to ensure that all power has been disconnected.

• Before connecting power, check that all mechanical parts, covers,

and doors have been returned to their original states. Make sure

there are no parts or tools left inside the device.

• Wiring method

• Maintenance and inspection

• When measuring current, a current transformer must be used with

the device.

• When the measured voltage exceeds the rated range (line voltage

of 35~600V AC L-L, phase voltage: 20~350V AC L-N) for this

device, a potential transformer must be used with the device.

• For the wrong forced pull-out of the wire, re-check the connecting

wire and start again.

• Disconnect all wiring (or power off all other circuits) that may

present potentially hazardous voltage levels to the unit when

cleaning the power meter. Ensure to use a dry and soft cotton cloth

to wipe the surface of the power meter carefully.
