Note
When measuring dielectric
strength of the equipment, be
sure to remove the surge
arrester, or the surge arrester
may be damaged.
Installing and wiring in compliance with EMC directive
Power supply for electromagnetic brake (for electromagnetic-brake motor only)
If an external DC power source is required for the use of the electromagnetic brake, use a DC
power source that complies with the EMC directive.
Use a shielded cable for wiring, and keep the wiring and grounding as short as possible. Refer
to “Wiring the signal cable” for details on how to ground the shielded cable.
Install the mains filter as close to the driver as possible, and use cable clamps and other means
to secure the input and output cables firmly to the surface of the enclosure. Connect the ground
terminal of the mains filter to the grounding point, using as thick and short a wire as possible.
Do not place the AC input cable (AWG18: 0.75 mm
2
or more) parallel with the mains-filter output
cable (AWG18: 0.75 mm
2
or more). Parallel placement will reduce mains-filter effectiveness if
the enclosure’s internal noise is directly coupled to the power-supply cable by means of stray
capacitance.
General
EMC directive (89/336/EEC, 92/31/EEC)
The
AS
series has been designed and manufactured for incorporation in general
industrial machinery. The EMC directive requires that the equipment incorporating this product
comply with these directives.
The installation and wiring method for the motor and driver are the basic methods that would
effectively allow the customer’s equipment to be compliant with the EMC directive.
The compliance of the final machinery with the EMC directive will depend on such factors as
the configuration, wiring, layout and risk involved in the control-system equipment and
electrical parts. It therefore must be verified through EMC measures by the customer of the
machinery.
Connecting mains filter for power source line
Connect a mains filter in the AC input line to prevent the noise generated in the driver from
propagating externally through the power-source line.
Use a mains filter or equivalent as below table.

Installing and wiring
Effective measures must be taken against the EMI that the
AS
series may give to
adjacent control-system equipment, as well as the EMS of the
AS
series itself, in
order to prevent a serious functional impediment in the machinery.
The use of the following installation and wiring methods will enable the
AS
series
to be compliant with the EMC directive (the aforementioned compliance standards).
