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
The standard models of the servo amplifier and servo motor comply with the EN Standard. In addition to
the instructions provided in this Instruction Manual, also follow the instructions below. If the model is not
specifically described to comply with the EN Standard in this Instruction Manual, it has the same
specifications as those of the standard models:
(1) Structure
24VDC
power
supply
Circuit
protector
Reinforced
insulation type
Servo
amplifier
Servo
motor
M
Control box
(2) 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).
(3) Power supply
Use a 24VDC power supply which has been insulation-reinforced in I/O.
(4) Grounding
To prevent an electric shock, fit the supplied earth terminal (E) to the servo amplifier and always
connect it to the earth (E) of the control box.
