Electric wiring

■
Be sure to carry out electric wiring in accordance with the terminal wiring diagram (below figure).
Wiring port
・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
・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.
