*1. The default settings are given for terminals S3 to S7. For a 3-wire sequence, the default settings are a 3-wire sequence for S5, multi- step speed setting

1 for S6 and multi-step speed setting 2 for S7.

*2. Do not use this power supply for supplying any external equipment.

*3. When driving a reactive load, such as a relay coil with DC power supply, always insert a flywheel diode as shown in Fig 6

*4. Pulse input specifications are given in the following table:

Low level voltage	0.0 to 0.8 V
High level voltage	3.5 to 13.2 V
H duty	30% to 70%
Pulse frequency	0 to 32 kHz

Flywheel diode

External power:	Coil
30 VDC max.	1 A max.

The rating of the flywheel diode must be at least as high as the circuit volt- age.

		Fig 6 Flywheel Diode Connection
		In Fig 4 the wiring of the digital inputs S1 to S7 is shown for the connection of contacts or NPN transis-
	1.
		tors (0V common and sinking mode). This is the default setting.
		For the connection of PNP transistors or for using a 24V external power supply, refer to Table 3.
IMPORTANT	2.	A DC reactor is an option only for Inverters of 18.5 kW or less. Remove the short circuit bar when con-
		necting a DC reactor.
