DANGER
Do not get close to or come into contact with rotating parts.
When touching the interior of the controller, abide by the following procedure to prevent
electric shocks.
i)
Shut off the source power supply to the hydraulic unit. (Set the power supply circuit
breaker of the circuit that is supplying the power to “OFF”.)
Hang a tag stating, for example, “Operation Prohibited (Work in Progress)” on the power
supply circuit breaker or other device, preventing erroneous operation while the work is
in progress.
ii) Wait at least 5 minutes before removing the cover, etc. from the controller. A capacitor
with a large capacity is used inside the controller, and working while the capacitor is
charged poses a risk of electric shock and other hazards. Always wait at least 5 minutes
(the time required to discharge the electric charge in the capacitor) before removing the
cover.
When running the unit, mount all the covers on the controller before turning the power on.
