35-10 WindO/I-NV4 User’s Manual
1.8 Wiring
● Power Supply Terminal
• Pin assignment is shown in the following table.
• Use applicable cables for wiring and recommended ferrules (made by IDEC, Weidmüller or Phoenix Contact) as
follows.
●
Caution when inserting and removing wires
• When connecting a wire that has not been treated with a tip, such as a stranded wire, you can connect it by
inserting the wire all the way in while pressing the pusher, and then releasing the pusher.
• When connecting wires with ferrules, connect the ferrules to the terminal block so that the long side is horizontal.
(See the figure below.)
• When pulling out the wire, use a flat blade screwdriver, etc., and pull the wire straight out while pressing the
pusher with about 20 N of force.
• Be careful not to damage the push-in terminals.
• When pressing the pusher, do not apply more than 40N of force. Also, do not pull out the wire without pressing the
pusher.
*1 Strip the sheath of the wire 7 to 9 mm from the end.
CAUTION
• Turn off the power supply before wiring.
• Make the wiring as short as possible and run all wires as far away as possible from high-voltage
and large-current cables. Follow all the procedures and precautions when wiring the HG2J-7U.
• Separate the HG2J-7U power supply wiring from the power lines of I/O devices and motor
equipment.
• Ground the functional earth terminal to make sure of correct operation.
• Use the SELV (Safety Extra-Low Voltage) circuit and LIM (Limited Energy) circuit for power supply.
• Use wire copper conductor only.
