Wiring Terminal Functions
•
P1-1 (AC / N) – For single-phase AC systems with a grounded neutral, connect the neutral AC line to
this terminal. For systems with two hot AC lines, connect either of the hot AC lines to this terminal.
•
P1-2 (AC / L) – For single-phase AC systems, connect the hot AC line to this terminal. For systems
with two hot AC lines, connect either of the hot AC lines to this terminal.
•
P1-3 (HI) – This is the POT HI reference terminal. This terminal must be connected to the most
positive speed pot input terminal (minimum 2.5VDC) of the partner control device. This terminal will
generally be referred to as Pot HI or +V for positive supplies, and Com for negative supplies.
•
P1-4 (WP) – This is the Wiper output terminal. This terminal will output an analog voltage signal
proportional to the referenced voltage signals connected to P1-3 (HI) and P1-5 (LO). This terminal
should be connected to the wiper or signal input of the partner control device.
•
P1-5 (LO) – This is the POT LO reference terminal. This terminal must be connected to the most
negative speed pot input terminal of the partner drive. This terminal will generally be referred to as Pot
LO or Com for positive supplies and –V for negative supplies.
•
P1-6 (COM) – This is the common point for the control logic. The speed sensor common lead as well
as any other equipment or source needing to reference the control common will be connected to this
terminal.
•
P1-7 (+5V) – This is a self-con5VDC power supply capable of up to 50 mA. The speed sensor
