COMPLIANCE WITH EC DIRECTIVES

1. WHAT ARE EC DIRECTIVES?
The EC directives were issued to standardize the regulations of the EU countries and ensure smooth
distribution of safety-guaranteed products. In the EU countries, the machinery directive (effective in
January, 1995), EMC directive (effective in January, 1996) and low voltage directive (effective in January,
1997) of the EC directives require that products to be sold should meet their fundamental safety
requirements and carry the CE marks (CE marking). CE marking applies to machines and equipment
into which servo amplifiers have been installed.

(1) EMC directive

The EMC directive applies not to the servo units alone but to servo-incorporated machines and
equipment. This requires the EMC filters to be used with the servo-incorporated machines and
equipment to comply with the EMC directive. For specific EMC directive conforming methods, refer to
the EMC Installation Guidelines (IB(NA)67310).

(2) Low voltage directive

The low voltage directive applies also to servo units alone. Hence, they are designed to comply with
the low voltage directive.
This servo is certified by TUV, third-party assessment organization, to comply with the low voltage
directive.

(3) Machine directive

Not being machines, the servo amplifiers need not comply with this directive.

2. PRECAUTIONS FOR COMPLIANCE
(1) Servo amplifiers and servo motors used

Use the servo amplifiers and servo motors which comply with the standard model.

(Note)

Note. The insulating transformer is not required for the 11kW or more servo amplifier.

(3) Environment

Operate the servo amplifier at or above the contamination level 2 set forth in IEC60664-1. For this
purpose, install the servo amplifier in a control box which is protected against water, oil, carbon, dust,
dirt, etc. (IP54).
