Danger
・
To protect the electric circuit and prevent electric shock, install the safety device such as a no fuse breaker
or a ground-fault interrupter on the main power source of the hydraulic unit so as to be based on the
European standard (EN60204-1).
(Refer to below table for the capacity of each machine)
・
In order to release the leakage from inverter circuit, ground (earth) terminal must be down to ground over
the third class. (Connect it directly not to pass through the breaker)
・
Wire after installing the machine surely.
・
Be sure to turn off the breaker of the main power source and confirm that the power source was interrupted
before the wiring,
・
Do not connect the supply line to the input and output terminal.
・
Never add the excessive power voltage beyond its specifications of the hydraulic unit
Caution
・
Since this hydraulic unit has protect-over current function built in, thermal for protect-over current function
is not necessary.
・
In case of using thermal, it may work wrong way by the inverter switching.
No fuse breaker
