Changing of the USA specification
main breaker for FANUC LASER C series
A-81053E-112
3-2. Changing of cable connection terminal
Please connect cable to use the recommended solderless terminal for each breaker, because it
changes the specification from a past Block Terminal to the Screw Terminal.
・Cable connection method for Screw Terminal（new specification）
3-3．About the function of Shunt Trip
The specification of the shunt trip which make turn off the breaker by DC24V voltage does not
change.
However, the method of shunt trip becomes two kinds types, one is supplied the voltage
directly to the breaker, and the other is converted the voltage to add a relay. (The additional relay
is installed in the laser oscillator. )
And, the coil of added relay has the polarity. Therefore, connect PF1 to plus and PF2 to minus of
terminal XT20 for external shunt trip conventionally. When it makes a mistake in the polarity, the
relay might be damaged.
