Specifications for the logic connection terminals are in the following table:

	Terminal Name	Description	Ratings
	[P24]	+24V for logic inputs	24VDC, 30 mA max (do not short to terminal L)
	[1], [2], [3], [4], [5]	Discrete logic inputs	27VDC max. (use P24 or an external supply refer-
			enced to terminal L)
	[L] (top row) *1	GND for logic inputs	sum of input 1-5 currents (return)
	[11], [12]	Discrete logic outputs	50mA maximum ON state current,
Operations Monitoringand			27 VDC maximum OFF state voltage
	[CM2]	GND for logic outputs	100 mA: sum of 11 and 12 currents (return)
	[FM]	PWM (analog/digital) output	0 to 10VDC, 1 mA, PWM and 50% duty digital
	[L] (bottom row) *1	GND for analog inputs	sum of OI, O, and H currents (return)
	[OI]	Analog input, current	4 to 19.6 mA range, 20 mA nominal
	[O]	Analog input, voltage	0 to 9.6 VDC range, 10VDC nominal,
			input impedance 10 kΩ
	[H]	+10V analog reference	10VDC nominal, 10 mA max
	[AL0]	Relay common contact	250 VAC, 2.5A (R load) max.,
			250 VAC, 0.2A (I load, P.F=0.4) max.
	[AL1]	Relay contact, normally
			100 VAC, 10mA min.
		closed during RUN
			30 VDC, 3.0A (R load) max.
	[AL2]	Relay contact, normally open	30 VDC, 0.7A (I load, P.F.=0.4) max.
		during RUN	5 VDC, 100mA min.

Note 1: The two terminals [L] are electrically connected together inside the inverter.
