Mitsubishi melservo-j2 series Instruction Manual page 3

1. To prevent electric shock, note the following:
• Before wiring or inspection, switch power off and wait for more than 10 minutes. Then, confirm the voltage
is safe with voltage tester. Otherwise, you may get an electric shock.
• Connect the servo amplifier 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 the servo amplifier and servo motor until they have been installed. Otherwise, you
may get an 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.
2. To prevent fire, note the following:
• Do not install the servo amplifier, servo motor and regenerative brake resistor on or near combustibles.
Otherwise a fire may cause.
• When the servo amplifier has become faulty, switch off the main servo amplifier 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
• 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 ( ,
• During power-on or for some time after power-off, do not touch the servo amplifier fins, regenerative brake
resistor, servo motor, etc. Their temperatures may be high and you may get burnt.
