WARNING
Do not open the front casing or terminal cover during operation or when power is connected.
This can cause electric shocks.
Do not operate with the front case or terminal cover open. This can cause electric shocks from
exposed high-voltage terminals or charged parts.
Even if the power is turned off, do not open the front casing or terminal covers, except to connect
wiring or conduct scheduled inspections. Charged components in the controller or servo amplifier
can cause electric shocks.
To avoid electric shocks, turn off the power, wait at least ten minutes, then check the voltage with
a tester before starting wiring or inspections.
Ground controllers, servo amplifiers, and servomotors to class 3 grounding resistance, or less.
Do not share a common ground with other equipment.
All wiring and inspections to be conducted by a trained technician.
Install controllers, servo amplifiers, and servomotors before connecting wiring. Otherwise,
electric shocks or injury can result.
Do not operate switches when your hands are wet. This can cause electric shocks.
Do not scratch, apply undue strain to, place heavy weights on, or trap cables. This can cause
electric shocks.
Do not touch controller, servo-amplifier, or servomotor terminal blocks while power is turned on.
This can cause electric shocks.
Do not touch the controller or servo amplifier internal power supply, internal ground, or signal
wires. This can cause electric shocks.
