Safety Instructions
General safety instructions
For qualified staff only
This manual is intended exclusively for acknowledged and qualified electricians who are totally
conversant with the safety standards of electrical drive and automation technology. Project
management, installation, setup, maintenance and testing of the equipment must be carried out
by an acknowledged and qualified electrician who is totally conversant with the safety standards
of electrical drive and automation technology.
Proper use of equipment
MELSERVO-Series equipment is only designed for use in the areas described in this manual.
Be sure to comply with all the characteristics stated in this manual. Only additional or
supplementary devices recommended by MITSUBISHI ELECTRIC EUROPE may be used.
Any other use or application of the products is deemed to be improper.
Relevant safety regulations
All safety and accident prevention regulations relevant to your specific application must be
observed in the system design, installation, setup, maintenance, servicing and testing of these
products.
The regulations listed below are particularly important. This list does not claim to be complete;
however, you are responsible for knowing and applying the regulations applicable to you.
●VDE/EN Standards
– VDE 0100
(Regulations for electrical installations with rated voltages up to 1,000V)
– VDE 0105
(Operation of electrical installations)
– VDE 0113
(Electrical systems with electronic equipment)
– VDE 0160
(Configuration of electrical systems and electrical equipment)
●Fire prevention regulations

Special instructions for working with this manual
In this manual special warnings that are important for the proper and safe use of the products
are clearly identified as follows:
mDANGER:
Personnel health and injury warnings. Failure to observe the precautions described
here can result in serious health and injury hazards.
bCAUTION:
Equipment and property damage warnings. Failure to observe the precautions
described here can result in serious damage to the equipment or other property.
NOTE means that incorrect handling may lead to erroneous operation of the servo
amplifier or servo motor. However, there is no risk to the health of the operators or of
damage to the equipment or other property.
This note is also used to indicate an other parameter setting, an other function, an other use
or it provides information for the employment of additional or supplementary devices.

Compliance with EC Directives
EC directives are intended to allow the liberal sales of goods within the EU. With the
establishment of “essential safety regulations” the EC directives ensure that technical barriers
to trade between member states of the EU are excluded. In the member states of the EU the
machine directive (in force since January 1995), the EMC directive (in force since January 1996)
and the low-voltage directive (in force since January 1997) of the EC directives determine the
guarantee of the presence of fundamental safety requirements and the display of the “CE” mark.
Conformity with EC directives is indicated by the submission of a Declaration of Conformity as
well as the display of the “CE” mark on the product, its packaging or its operating instructions.
The above directives relate only to devices and systems and not to single components, unless
the components have a direct function for the end user. As a servo amplifier together with a
servo motor have to be installed with a controller and other mechanical parts in order to serve
a useful purpose for the end user, servo amplifiers do not possess this function. Consequently
they can be described as a complex component for which a conformity declaration or the “CE”
mark is not required. This position is also supported by CEMEP, the European association of
manufacturers of electronic drive technology and electrical machines.
The servo amplifiers do, however, comply with the relevant low-voltage directive, which is a
prerequisite for the “CE” mark on machines or accessories in which the servo amplifier is used.
To ensure conformity with the requirements of the EMC directive, MITSUBISHI ELECTRIC has
produced the manual “EMC INSTALLATION GUIDELINES” (article number: 103944) in which
the installation of the servo amplifier, the construction of a control cabinet and other installation
tasks are described. Please contact the relevant sales partner who is responsible for you.

Special safety instructions
The following notes on sources of danger should be interpreted as general guidelines for servo
drives in association with other devices. These precautions must always be observed in the
design, installation and operation of all control systems.
mDANGER:
●
Observe all safety and accident prevention regulations applicable to your specific
application. Installation, wiring and opening of the assemblies, components and
devices may only be performed with all power supplies disconnected.
● Prior to carrying out any installation work, wiring and opening assemblies,
components and devices you must disconnect the power supply to the units and
wait for at least 10 minutes. Prior to touching anything measure the residual voltage
in condensers, etc. with a voltmeter to ensure that the voltage has been sufficiently
reduced.
● Never touch the servo amplifier or servo motor or the optional brake resistor during
or shortly after operation whilst they are still live. The components can get very hot
– there is a risk of getting burned.
● Assemblies, components and devices must always be installed in a shockproof
housing fitted with a proper cover and protective equipment.
● Devices with a permanent connection to the mains power supply must be integrated
in the building installations with an all-pole disconnection switch and a suitable
fuse.
● Ground the servo amplifier and servo motor securely.
● Check power cables and lines connected to the equipment regularly for breaks and
insulation damage. If cable damage is found, immediately disconnect the equipment
and the cables from the power supply and replace the defective cabling.
● Before using the equipment for the first time check that the power supply rating
matches that of the local mains power.
● EMERGENCY OFF facilities in accordance with VDE 0113 must remain effective in
all operating modes of the servo motor. The EMERGENCY OFF facility reset function
must be designed so that it cannot cause an uncontrolled or undefined restart.
● The EMERGENCY OFF facility must be wired so that the electromagnetic brake is
also activated during an EMERGENCY OFF.
● Residual current protective devices pursuant to DIN VDE Standard 0641 Parts 1–3
are not adequate on their own as protection against indirect contact for installations
with servo amplifier. Additional and/or other protection facilities are essential for
such installations.
