Mitsubishi Electric Q170MSCPU-S1 - Prevention of Electric Shocks; Fire Prevention

2
1. Prevention of electric shocks
2. For fire prevention
DANGER
 Never open the front case or terminal covers while the power is ON or the unit is running,
as this may lead to electric shocks.
 Never run the unit with the front case or terminal cover removed. The high voltage terminal
and charged sections will be exposed and may lead to electric shocks.
 Never open the front case or terminal cover at times other than wiring work or periodic
inspections even if the power is OFF. The insides of the Motion controller and servo
amplifier are charged and may lead to electric shocks.
 Completely turn off the externally supplied power used in the system before mounting or
removing the module, performing wiring work, or inspections. Failing to do so may lead to
electric shocks.
 When performing wiring work or inspections, turn the power OFF, wait at least ten minutes,
and then check the voltage with a tester, etc.. Failing to do so may lead to electric shocks.
 Be sure to ground the Motion controller, servo amplifier and servo motor. (Ground
resistance : 100  or less) Do not ground commonly with other devices.
 The wiring work and inspections must be done by a qualified technician.
 Wire the units after installing the Motion controller, servo amplifier and servo motor. Failing
to do so may lead to electric shocks or damage.
 Never operate the switches with wet hands, as this may lead to electric shocks.
 Do not damage, apply excessive stress, place heavy things on or sandwich the cables, as
this may lead to electric shocks.
 Do not touch the Motion controller, servo amplifier or servo motor terminal blocks while the
power is ON, as this may lead to electric shocks.
 Do not touch the built-in power supply, built-in grounding or signal wires of the Motion
controller and servo amplifier, as this may lead to electric shocks.
CAUTION
 Install the Motion controller, servo amplifier, servo motor and regenerative resistor on
incombustible. Installing them directly or close to combustibles will lead to fire.
 If a fault occurs in the Motion controller or servo amplifier, shut the power OFF at the servo
amplifier’s power source. If a large current continues to flow, fire may occur.
 When using a regenerative resistor, shut the power OFF with an error signal. The
regenerative resistor may abnormally overheat due to a fault in the regenerative transistor,
etc., and may lead to fire.
 Always take heat measures such as flame proofing for the inside of the control panel
where the servo amplifier or regenerative resistor is installed and for the wires used.
Failing to do so may lead to fire.
 Do not damage, apply excessive stress, place heavy things on or sandwich the cables, as
this may lead to fire.
