AC Power Connections

Terminals with an integrated AC power supply have these power ratings.

Protective Earth and Functional Earth Connections

PanelView Plus 6 devices with an AC power input have a protective earth
terminal you must connect to a low-impedance earth ground. The protective
earth terminal is on the power input terminal block.

Table 40 - AC Power Ratings

Terminal

Input Voltage

Power Consumption

400, 600

100…240V AC (50…60 Hz)

35VA max

700, 1000, 1250, 1500

85…264V AC (47…63 Hz)

160VA max

IMPORTANT

In addition to the protective earth connection, the 700 and 1500 terminals also
have a functional earth terminal that you must connect to a low-impedance
earth ground. The functional earth connection is on the back of the display.

ATTENTION: The protective earth and functional earth connections to ground
are mandatory.

The functional earth is required for Electromagnetic compliance (EMC) with the

European Union (EU) EMC directive for CE-mark conformance.

The protective earth is required for both safety and regulatory compliance.
