7. Measures to satisfy the standards

7.1 How to cope with the CE standards

7.1.1 Measures to satisfy the EMC directive

Concrete measures to EMC directive are shown below.
(1) This inverter installs a EMC filter inside. So the conducted and radiated noise can be reduced.
Inverter type form
VFPS1-4007PLE~VFPS1-4055PLE
VFPS1-4075PLE~VFPS1-4185PLE
VFPS1-4220PLE
VFPS1-4300PLE~VFPS1-4900PLE
VFPS1-4007PDE~VFPS1-4150PDE
VFPS1-4185PDE~VFPS1-4450PDE
VFPS1-4550PDE~VFPS1-4900PDE
(2) Use shielded power cables and control signal cables for the input and output lines of the inverter. Route the
cables and wires so as to minimize their lengths. Keep a distance between the power cable and the control cable
and between the input and output wires of the power cable. Do not route them in parallel or bind them together,
instead cross at right angle.
(3) To limit the radiation noise from cables, fix the motor cable to the wiring port plate with metal cable gland.
(4) To further limit the radiation noise, insert a zero-phase reactor in the inverter output line and insert ferrite cores in
the earth cables.
