DANGER
[1] Do not access or touch rotating parts.
[2] If you touch internal components of the controller, observe the following procedure to prevent electric
shock.
i) Turn OFF the hydraulic unit main power supply.
(Turn OFF the power supply circuit breaker.)
To prevent erroneous operation during work, post an "Operation Prohibited (During Work)" sign on
the power supply circuit breaker.
ii) Remove the controller cover after elapse of at least five minutes.
The controller uses a large-capacitance capacitor. If you work with the capacitor charged, you may
get electric shock. Before removing the controller cover, be sure to leave the controller for at least
five minutes to discharge electricity from the capacitor.
[3] Before turning ON the power supply to start operation, mount all covers to the controller.
