10. Requirement for the compliance with EMC Directives EMC

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-PX4 and EMU4-AX4) 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.

(1)Harmonized standard for EMC Directives: EN61326-1:2013 (a)Compatibility condition for harmonized standard

The energy measuring unit is the open type device (i.e. the device incorporated in other device), and needs to be installed in the conductive control panel. The unit is tested with installed in the control panel for the emission and the immunity out of the test items for the standard.

(2)Recommended condition for installation in the control panel (a)Control panel

Control panel needs to have conducting property. When bolting the top panel, bottom panel etc. of the control panel, mask the grounding part of the

panel so as not to be painted. 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 Set up the ground point to the control panel near the energy measuring unit, and ground the frame

GND terminal of the unit to the ground terminal of the control panel (PE) by as thick and short wires as possible. (wire length is 30cm or shorter)

(3)Cable

(a)Auxiliary power, Input voltage, CC-Link cable, MODBUS cable, Small display unit cable

When it is necessary to comply with the EMC Directive (EN-61326-1), attach ferrite cores to each cable. Ferrite cores used in our testing is below.

Auxiliary power
