From the panel front, pass the main unit through the square holes. Insert the mounting frame from the
rear and push it in so that the gap between the mounting frame and the panel surface is minimized.
Tighten the screws (2 places) equally tight and check that there is no rattling. If the screws are overly
tightened, the frame may come off. In that case, loosen the screws and tighten them again pushing the
frame in.

Please connect a breaker (3 to 15A) to the voltage input part for safety reasons and to protect the device. Grounding the secondary side of VT (Voltage transformer) and CT (Current transformer) is not necessary with low-voltage circuit.
When measuring load with 100-200V system

When measuring a load with exceed input voltage.
Voltage transformer (VT) is needed when you measure a load with over rated input voltage (240V).
Use VT, those secondary rating is 110V.
Grounding the secondary side of VT and CT is not necessary with low-voltage circuit.

|
Note: | Short-circuit impedance should be less than 1kΩ.(When the impedance is 0Ω, drain current is approx. 5mA.) The open-circuit impedance should be more than 100kΩ. |
---|
Note: | Operating power supply input part (measured voltage input) is not insulated to pulse input parts. So the input equipment must have the power supply transformer in which the secondary side is not grounded with the primary and secondary sides insulated, in order to prevent interference of the power supply circuit when connecting the external input circuit. Be sure not to use an auto-transformer. |
