3. Secure the DC power wires to the marked terminals (+ and –) on the
terminal block.
4. Secure the earth ground wire to the GND terminal on the terminal
block.
The GND terminal must be connected to a low-impedance earth
ground.
5. Apply power to the operator terminal.
Connect to AC Power
(1)
Terminals with an AC power supply have these power ratings:
• 100…240V AC (50…60 Hz)
• 105VA maximum
To connect the operator terminal to an AC power source, follow these steps.
1. Verify that the wiring is not connected to a power source.
2. Strip 7 mm (0.28 in.) of insulation from the ends of the wire.
ATTENTION: The earth ground connection to ground is mandatory.
This connection is required for noise immunity, reliability, and
Electromagnetic Compliance (EMC) with the European Union (EU)
EMC Directive for CE marking conformance. This connection is
required for safety by Underwriters Laboratory.

Performance Terminals
Stainless Steel Terminals
(1) Available on Series A terminals only.
ATTENTION: Improper wiring of the power terminals can result in voltage at
the communication connector shells.
Do not apply power to the terminal until all wiring connections have been
made. Failure to do so can result in electric shock.
Do not connect stainless steel terminals to AC power. Stainless steel terminals
are only compatible with DC power.
