Hitachi hitachi series inverter Wiring sample of control logic terminal sink logic, Sp, Sn

O	Analog voltage input	0 to 9.8 VDC range, 10 VDC nominal,
		input impedance 10 kΩ
H	+10V analog reference	10VDC nominal, 10mA max.
SP, SN	Serial communication terminal	For RS485 Modbus communication.
AL0, AL1, AL2 *3	Relay common contact	250VAC,	2.5A	(R load) max.
		250VAC,	0.2A	(I load, P.F.=0.4) max.
		100VAC,	10mA	min.
		30VDC,	3.0A	(R load) max.
		30VDC,	0.7A	(I load, P.F.=0.4) max.
		5VDC, 100mA		min.

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

Note 2: We recommend using [L] logic GND (to the right) for logic input circuits and [L] analog GND (to the left) for analog I/O circuits.

Note 3: Refer to page 39 for details of trip signals.

Note: If relay is connected to intelligent output, install a diode across the relay coil (reverse-biased) in order to suppress the turn-off spike.

Caution for intelligent terminals setting

In turning on power when the input to the intelligent terminals become the following operations, the set data might be initialized.

Please ensure not becoming the following operations, in changing the function allocation of the intelligent input terminal.

1)Turning on power while [Intelligent input terminal 1/2/3 are ON] and [Intelligent input terminal 4/5/6/7 are OFF].

2)After 1)'s condition, turning off power.

3)After 2)'s condition, turning on power while [Intelligent input terminal 2/3/4 are ON] and [Intelligent input terminal 1/5/6/7 are OFF].
