Shielded cable	Strip the cable and fix it to the metal plate by means
	of a metal saddle for electrical work or equivalent.

(1) Shingle-phase 100V class		: VFNC1-1001P to 1007P

This subsection explains what measures must be taken to satisfy the EMC directive.
Insert a recommended EMI filter (Table 2) on the input side of the inverter to reduce radiation
and transmission noises. In the combinations listed in Table 2, inverters were checked for
conformity with the EMC directive. For inverters used in Japan, it is recommended to use the
NF series of noise filters.
Table 2 lists noise filters recommended for the inverters.

(2)The main cables such as input to the EMI filter and output of the inverter and the signal cables should be shielded, then cable length should be wired as short as possible. The main input cable should be separated from the main output cable, and cables for control signal also should be separated from main cables, not wiring parallel and not bundling, cross the wires where necessary.

(3)Install EMI filter and inverter on the same metal back plate in an inverter panel. The metal back plate or the cubicle must be grounded absolutely, by using short thick wires, separated from the main cables.

(4)Please separate input cable to EMI filter from output cable as much as possible.

(5)Shielded cables should be grounded on the metal back plate in order to reduce the radiated noise from the other cables. It is an effective measure that shielded cables are grounded close to the inverter or/and operation panel or/and EMI filter(less than 10cm).
