To install the terminal block, follow these steps.
1. Reattach the terminal block to the connector until seated.
2. Tighten the two screws that secure the terminal block to the connector.
Connect to DC Power
Terminals with a 24V DC power supply have these power ratings:
• 24V DC nominal (18…30V DC)
• 50 W maximum (2.1 A at 24V DC)
Terminals with a DC power input support operation from a safety extra low
voltage (SELV) or protective extra-low voltage (PELV) 24V DC power supply.
Supported power supplies include catalog numbers 1606-XLP95E,
1606-XLP100E, or 2711P-RSACDIN.
You can power the terminal from the same power source as other equipment by
using a DC power bus.
To connect the operator terminal to a DC 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 wires.
ATTENTION: Do not use excessive force to press the terminal block
into position. The terminal blocks are keyed to fit the DC or AC
connector. If the terminal block does not fit into the connector,
verify that you have the correct terminal block. See Table 7 on
page 23.
ATTENTION: The power supply is internally protected against reverse
polarity. To avoid damage to the terminal:
• Do not connect DC+ or DC- to the earth ground terminal.
• Do not connect AC power, or more than 30V DC, to the power terminal block.
ATTENTION: Use a SELV or PELV supply as required by local wiring codes for
your installation. The SELV and PELV power sources provide protection so
that under normal and single fault conditions, the voltage between
conductors and earth ground does not exceed a safe value.
