is safe with voltage tester. Otherwise, you may get an electric shock.
Connect the base unit and servo motor to ground.
Any person who is involved in wiring and inspection should be fully competent to do the work.
Do not attempt to wire for each unit and the servo motor until they are installed. Otherwise, you can obtain
the electric shock.
Operate the switches with dry hand to prevent an electric shock.
The cables should not be damaged, stressed, loaded, or pinched. Otherwise, you may get an electric
shock.
During power-on or operation, do not open the front cover of the servo amplifier. You may get an electric
shock.
Do not operate the servo amplifier with the front cover removed. High-voltage terminals and charging area
are exposed and you may get an electric shock.
Except for wiring or periodic inspection, do not remove the front cover even of the servo amplifier if the
power is off. The servo amplifier is charged and you may get an electric shock.
2. To prevent fire, note the following: CAUTION
Do not install the base unit, servo motor and regenerative brake resistor on or near combustibles.
Otherwise a fire may cause.
When each unit has become faulty, switch off the main base unit power side. Continuous flow of a large
current may cause a fire.
When a regenerative brake resistor is used, use an alarm signal to switch main power off. Otherwise, a
regenerative brake transistor fault or the like may overheat the regenerative brake resistor, causing a fire.
3. To prevent injury, note the follow CAUTION
Only the voltage specified in the Instruction Manual should be applied to each terminal. Otherwise, a
burst, damage, etc. may occur.
Connect the terminals correctly to prevent a burst, damage, etc.
Ensure that polarity ( , ) is correct. Otherwise, a burst, damage, etc. may occur.
Take safety measures, e.g. provide covers, to prevent accidental contact of hands and parts (cables, etc.)
with the servo amplifier heat sink, regenerative brake resistor, servo motor, etc.since they may be hot
while power is on or for some time after power-off. Their temperatures may be high and you may get
burnt or a parts may damaged.
During operation, never touch the rotating parts of the servo motor. Doing so can cause injury.

(4) Usage CAUTION
Provide a emergency stop circuit to ensure that operation can be stopped and power switched off
immediately.
Any person who is involved in disassembly and repair should be fully competent to do the work.
Before resetting an alarm, make sure that the run signal of the servo amplifier is off to prevent an accident.
A sudden restart is made if an alarm is reset with the run signal on.
Do not modify the equipment.
Use a noise filter, etc. to minimize the influence of electromagnetic interference, which may be caused by
electronic equipment used near MELSERVO-J2M.
Burning or breaking each unit may cause a toxic gas. Do not burn or break each unit.
Use the drive unit with the specified servo motor.
The electromagnetic brake on the servo motor is designed to hold the motor shaft and should not be used
for ordinary braking.
For such reasons as service life and mechanical structure (e.g. where a ballscrew and the servo motor
are coupled via a timing belt), the electromagnetic brake may not hold the motor shaft. To ensure safety,
install a stopper on the machine side.
(5) Corrective actions CAUTION
When it is assumed that a hazardous condition may take place at the occur due to a power failure or a
product fault, use a servo motor with electromagnetic brake or an external brake mechanism for the
purpose of prevention.
Configure the electromagnetic brake circuit so that it is activated not only by the interface unit signals but
also by a forced stop (EM1).

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 (MELSERVO-J2M is contained) 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 MELSERVO-J2M. Hence, they are designed to comply with
the low voltage directive.
MELSERVO-J2M is certified by TUV, third-party assessment organization, to comply with the low
voltage directive.
(3) Machine directive
Not being machines, MELSERVO-J2M need not comply with this directive.
