2.1 Safety Notes

Always be aware of the following safety notes when installing, wiring, operating, maintaining, and

checking the device.

◆ Notes on Installation

Install the power meter according to instructions on the manual. Otherwise, damage on the device might result.

It is forbidden to expose and use this product in a place present with matters, such as water vapor,

corrosive and ﬂammable gas. Otherwise, electric shock, re, or explosion might result.

Do not install the meter in an environment with a temperature that exceeds range on the specication.

Otherwise, inability of the meter to operate normally or damage on the meter might result.

Do not use the meter on an alarm console that might cause personnel injury or death, damage on the device, or system shutdown.

◆ Note on Wiring

Keep a good grounding on the grounded terminals, as improper grounding might cause

abnormal communication, electric shock, or re.

◆ Notes on Operation

Do not alter wiring with power turned on. Otherwise, electric shock or personnel injury might result.

Do not touch the panel with a sharp item. Otherwise, indentation on the panel might result, which causes the meter to not function normally.

◆ Maintenance and Check

Do not get to inside of the meter. Otherwise, electric shock might result.

Do not take the meter panel apart when the power is on. Otherwise, electric shock might result.

Do not touch the wiring terminals within 10 minutes after turning off power, as the remaining voltage

might cause electric shock.

Do not block ventilation ducts when operating the meter. Otherwise, the meter will breakdown

because of inadequate heat dissipation.

◆ Methods of Wiring

Do not use voltage that exceeds range specied for the meter. Otherwise, electric shock or re might result.

When wiring, take apart the quick connector from the main meter body.

Connect only one cord on one plug on the quick connector.

For wrongfully forced unplug, recheck the connecting cord and restart.

◆ Wiring for Communication Circuits

Follow the standard specication on use of wires for communication wiring.

Length of communication wires should be within the specied standard.

Use correct grounding loop to avoid communication issues.

To avoid stronger noise interference that causes the meter to not operate normally, use an independent

wiring slot to separate the communication cable for the meter from all power cords and motor power cords.

Notes

Step 1:

Open the square hole on the metal plate and then

install the power meter.

Step 2:

Install the fixing mount into the sliding slot and

then push the meter in to touch the metal plate.

Step 3:

4.2 Basic Checks

Items Checked Contents of Checks

General Check

■Regularly check for losing of the xing mount at the location where the power

meter and device are connected.

■Guard against entrance of foreign objects, such as oil, water, or metal powder at

the heat dissipating holes. Guard against entrance of drill cut powders into the

power meter.

■Should the power meter be installed at a place present with harmful gas or dust,

guard against entrance of those matters into the meter.

Pre-operation

Check

(not supplied with

control power)

■Insulate the connecting spot of the wiring terminals.

■Communications wiring should be done properly, or abnormal operations might

result.

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

pieces, in the power meter.

■Should electronic devices used near the power meter experience electromagnetic

interference, tune with instruments to reduce electromagnetic interference.

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

Pre-running Check

(supplied with

control power)

■Check whether power indicator light is lit.

■Check whether communication between every device is normal.

■If there is any abnormal response from the power meter, contact your distributor

or our customer service center.

5.1 Wiring on the Back

This chapter illustrates how the wiring on the back is done.

Note:

■To avoid electric shock, do not alter wiring when the power is on.

■As there is no power switch on the power meter, be sure to install a breaker switch on the power cord for the meter.

Recommended wiring materials are shown below:

Connecting Terminals Wire Diameters Screw Turning Torque

Functional Power AWG 10~24 7.14 kgf-cm (0.7 N*m)

Measured Voltage AWG 10~26 7.14 kgf-cm (0.7 N*m)

Measured Current AWG 14~22 8.0 kgf-cm (0.79 N*m)

RS-485 AWG 14~28 2.04 kgf-cm (0.2 N*m)

RTwisted pair cables must be used in cabling for RS485 communication. When connecting multiple

devices in series, the wiring method is displayed in the diagram below.

The D+ communication terminal for all devices should be connected on the same twisted pair cable. The

D- terminals should be connected on the other twisted pair cable. The insulation net is grounded. The

device on the end terminal needs to have terminal resistor installed on it.
