EG
Common
Ground terminal for Q1 (open collector).
24
24 VDC power
supply
Primary use is for supplying the digital input
terminals in PNP mode. May be used for other
purposes (EX: 2-wire transducer). Caution on the
limited power rating of the “24” terminal.
Specifications:
24VDC Maximum output current: 100 mA

Send / receive RS-485 signals. Refer to 10, RS-485
Communication Features on page 299 for more
details.
Note
• STP (Shielded Twisted Pair) cable has a highly conductive shielded screen around
twisted cable pairs. STP cables protect conductors from electromagnetic interference.
• When making wiring connections at the control terminals ensure that the total cable length
does not exceed 165 ft (50 m).
• Ensure that the length of any safety related wiring does not exceed 100 ft (30 m).
• Ensure that the cable length between the keypad and the inverter does not exceed 50 ft
(15.24 m). Cable connections longer than 50 ft (15.24 m) may cause signal errors.
• Use a ferrite core to protect signal cables from electro-magnetic interference.
• When using cable ties on control wiring, apply the cable ties no closer than 6 inches from
the inverter. This provides sufficient access to fully close the terminal cover.
