AC line input current (RMS) is dependent on total line impedance.

Recommended type of external input fuse:
AC line input: Branch circuit protection fuse, e.g., IEC 269-1/gG, EN 60269-1, VDE 0636/gL, UL Class
J, or equivalent.
DC bus input: Semiconductor protection fuse, 660 V or 750 V, superfast, e.g., A70P500, VDE 0636/aR,
or equivalent.
GV3000/SE drives set up for FVC regulation require an encoder for closed-loop
operation. Refer to table A.5 for specifications. Drives set up for V/Hz or SVC
regulation do not require an encoder for feedback.
Encoder connections are considered signal level wiring and, therefore, must be run
separate from control and power wiring. Reliance Electric recommends 18 AWG
unshielded twisted pair wires with 2-3 twists per inch for applications to a maximum
distance of 303 meters (1000 feet). The recommended Reliance Electric part number
is 417900-207CG; 18 AWG, 6 conductor (3 twisted pairs).
Motor Full Load Amps
Verify that the GV3000/SE output current rating is greater than the motor's full load
current (amps). Table 2.1 lists the output current values.
