ONNECTING THE PROTECTIVE GROUNDING
The DM4380 has a place on its rear panel to attach a cable to connect the Protective
Grounding.
The grounding cable is not part of the basic accessories shipped with the switch. The
cable indicated for the installation must have a thickness of 10 to 12 AWG. The color of
the cable must follow the specific requirements of the country where the switch will be
installed; most countries determine that the cable should be green with yellow stripes.
Step 1
Locate the grounding connector located in the back of the
equipment, as shown in figure 16, and remove the connector
with a Philips screwdriver.
Step 2
Secure the cable to the grounding connector.
Step 3
Cut the cable at a suitable length to connect it with the
grounding installation.
Step 4
Screw the connector to the equipment using the same screw
removed in step 1.
Step 5
Secure the other end of the cable to the installation ground.

ENTILATION
The DM4380 ventilation airflow is provided by the inlets on the front side of the
equipment and through the outlets on the rear, as in figure 18. For the correct
operation of the cooling system it is important that the air inlets and outlets are
unobstructed and that the free areas of 2 inches are respected on the rear panel and
on the left side of the switch. These areas must have free air circulation so that the
temperature of the equipment remains within the assured levels of operation, also
observing the cooling of the environment.
