1.3 Safety Precautions

 Installation Notes

 Install the power meter according to instructions on the manual. Use appropriate

personal protective equipment (PPE) and follow safe electrical work practices.

 Only qualified electrical workers should install this equipment. Such work should be

performed only after reading the entire set of installation instructions.

 Operate the power meter according to instructions on the manual. Neglecting

fundamental installation requirements may lead to personal injury as well as damage
to electrical equipment or other property.

 This equipment should be installe d in a suit able insulated and fireproof enclosure.

 Operation Notes

 DO NOT work alone.
 Before performing visual inspections, tests, or maintenance on this equipment,

disconnect all electric power sources.



Always use a properly rated voltage sensing device to confirm that power is off.

 Replace all devices, doors and covers before turning on power to this equipment.
 Carefully inspect the work area for tools and objects that may have been left inside

the equipment.

 Operation Notes

 Never short the secondary of a Power Transformer (PT).
 Never open circuit a Current Transformer (CT)



Ensure that the CT secondary winding is fixed securely on the equipment. It may
damage the equipment if the secondary winding becomes loose during operation.



When used with CTs, make sure the CTs are UL2808 listed in America and Canada
and meet or exceed the accuracy specifications for IEC61869-2 class or accepted by
authority having jurisdiction (AHJ) in other areas.

 Wiring Notes

 When the measured current is higher than the rated specification for the device,

consider using an external current transformer (CT).

 When the measured voltage is higher than the rated specification for the device,

consider using an external potential transformer (PT) (line voltage: 35 to 690V AC L-L
or phase voltage: 20 to 400V AC L-N).

 Connect only one cord to one plug on the quick connector.
 For the device is accidently unplugged, check the connecting cord and restart.

 Maintenance and Inspection Notes

 While cleaning the equipment, be sure to unplug all external power sources first. Use

a dry cloth to clean the equipment’s exterior. DO NOT open the equipment or touch
the wiring inside to prevent personal injury as well as damage t o el ect rical equ ipm ent
or other property. DO NOT use aerosol sprays, solvents, or abrasives.

3.2 Basic Checks

Items

Contents

General Check

 Regularly check for mounting looseness where the power meter and device are

connected.

 Prevent foreign objects, such as oil, water, or metal powder entering the device through

the ventilation holes. Prevent drill shavings or other debris entering the power meter.

 If the power meter is installed at a location with harmful gas or dust, prevent those

materials from entering the power meter.

Pre-operation

Check

(not supplied

with power)

 Insulate the connections at the wiring terminals.
 Communications wiring should be done properly to prevent abnormal operations.

 Check for the presence of conducive and flammable objects, such as screws or metal

pieces in the power meter.

 If electronic devices near to the power meter experience electromagnetic interference,

take steps to reduce the electromagnetic interference.

 Check for the correct voltage level for the power supplied to the power meter.

Pre-running

Check

(supplied with

power)

 Check if the power indicator light is lit.
 Check if communication between every device is normal.
 If there is any abnormal response from the power meter, contact your distributor or our

customer service center.

3.3 Wiring

3.3.1 Wiring Diagrams

 To avoid electric shock, do not change the wiring when the power is on.
 Install a breaker switch on the power cord for the meter because there is no power switch on the power

meter.

 When the measured volt age is higher than the r a ted spe cifi ca t ion for the device, it is necessary to use a n

external potential transformer (PT).

 When the measured current is higher than the rated specification for the device, it is necess ary to use an

external current transformer (CT).
