Ground Fault Circuit Interrupter
The Ground Fault Circuit Interrupter (GFCI) is wired in series from the AC power input to the servo
amplifier. It monitors both AC power leads to the servo amplifier, ensuring that current flowing in one
lead is the same as the current flowing out the other lead. If, due to a ground fault, the GFCI detects a
net difference in the AC power exceeding 30 milliamps (30mA or .300 Amps), it shuts off the AC
power to the servo amplifier automatically.

Fuses
The main power fuses use a 15A, 250V, SLO-BLO Littelfuse 326015 or equivalent
(part number 13-10-1015).
