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, fire, or explosion might result.
»
Do not install the meter in an environment with a temperature that exceeds range on the specification.
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 fire.
◆
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 specified for the meter. Otherwise, electric shock or fire 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 specification on use of wires for communication wiring.
»
Length of communication wires should be within the specified 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.
