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.

(2) Configuration
The control circuit provide safe separation to the main circuit in the 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).
