Compliance to European EC Directives
1. European EC Directives
The European EC Directives were issued to unify Standards within the EU Community and to smooth
the distribution of products of which the safety is guaranteed. In the EU Community, the attachment
of a CE mark (CE marking) to the product being sold is mandatory to indicate that the basic safety
conditions of the Machine Directives (issued Jan. 1995), EMC Directives (issued Jan. 1996) and the
Low-voltage Directives (issued Jan. 1997) are satisfied. The machines and devices in which the servo
is assembled are a target for CE marking.
The servo is a component designed not to function as a single unit but to be used with a combination
of machines and devices. Thus, it is not subject to the EMC Directives, and instead the machines and
devices in which the servo is assembled are targeted.
This servo complies with the Standards related to the Low-voltage Directives in order to make CE
marking of the assembled machines and devices easier. The EMC INSTALLATION GUIDELINES (IB
(NA) 67303) which explain the servo amplifier installation method and control panel manufacturing
method, etc., has been prepared to make compliance to the EMC Directives easier. Contact
Mitsubishi or your dealer for more information.
2. Cautions of compliance
Use the standard servo amplifier and EN Standards compliance part (some standard models are
compliant) for the servomotor. In addition to the items described in this instruction manual, observe
the items described below.
(1) Environment
The servo amplifier must be used within an environment having a Pollution Class of 2 or more as
stipulated in the IEC664. For this, install the servo amplifier in a control panel having a structure
(IP54) into which water, oil, carbon and dust cannot enter.
(2) Power supply
1) The servo amplifier must be used with the overvoltage category II conditions stipulated in
IEC664. For this, prepare a reinforced insulated transformer that is IEC or EN Standards
complying at the power input section.
2) When supplying the control signal input/output power supply from an external source, use a
24 VDC power supply of which the input and output have been reinforced insulated.
(3) Installation
1) To prevent electric shocks, always connect the servo amplifier protective earth (PE) terminal
(terminal with
2) When connecting the earthing wire to the protective earth (PE) terminal, do not tighten the
wire terminals together. Always connect one wire to one terminal.
(4) Wiring
1) Always use crimp terminals with insulation tubes so that the wires connected to the servo
amplifier terminal block do not contact the neighboring terminals.
