*Momentary means: Energizing 9 times for 0.5 seconds at 1-minute intervals, and then 1 time for 5 seconds.

Can the unit be used as an electric energy meter?

This unit cannot be used for deal and proof of electric energy measurement stipulated in the measurement law.

Are errors in wiring verifiable easily?

They are verifiable by the indication for discrimination support function for improper connection. ( p.37-46)

If a load such as welding equipment exists, a current flows only for a short period (e.g. 2 cycles). Is measurement possible?

11. Requirement for the compliance with EMC Directives

EMC Directives prescribe both “Emission (electromagnetic interference): Do not radiate strong electromagnetic waves outside”

and “Immunity (electromagnetic susceptibility): Do not be influenced by electromagnetic waves from outside”.

This section compiles the precautions for the compliance of the system incorporating the energy measuring unit (target model: EMU4-FD1-MB) with the EMC Directives. The following description is based on the requirement of the regulations and the standards we understand, but we do not guarantee to comply with the directives above for the whole system built in accordance with this description. The manufacturer of the system finally needs to evaluate the way of the compliance with EMC Directives and whether the system complies with them or not.

･ In inner panel, keep the conductivity in as large area as possible by masking the bolting part to the main panel to keep the

electric contact to main panel.

･ Ground the main panel by the thick wire so as to keep high impedance even for high-frequency wave.

(b) Installation of power line and ground line
