2. Secure the 24V DC power wires.

3. Secure the functional earth ground wire to the functional earth ground terminal screw

on the terminal block.

4. Apply 24V DC power to the terminal.

Ground the Module

The optimum method for grounding electronic equipment is to ground it separately from other
high-power systems, and to ground more than one unit of electronic equipment with a
single-point ground. For example, connect the Micro820 controller to the Remote LCD on the
same ground port.

The grounding marked terminal (see the following drawing) is provided on the unit.

The functional earth terminal wiring requires a minimum wire gauge.

IMPORTANT

Do not use a ground that has an unstable impedance, such as painted
screws, or ground subject to vibration.

ATTENTION: The functional earth 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-mark conformance.
