2. A separate enclosure ground wire must be connected between the enclosure ground lug and an earth
ground connection provided by a ground rod installed at the power supply site. In most cases, one
copper or copper-clad steel ground rod of 2.5 meter (8 feet) length driven into the earth will be sufficient
to provide the ground connection required. In some instances, a more elaborate grounding method (such
as a ring ground) may be required; however, this may be dictated by state or local codes and depends on
conductivity of the soil within the installation area.
3. The dead metal of the service entrance box
must
be bonded to the metal enclosure that houses the
power supply. Additionally, the ground bar within the service entrance box should be bonded to the metal
enclosures; however, this requirement may be subject to local codes and practices.
4. The grounding wire connected between the power supply enclosure and the earth ground rod should be
no smaller in area than 13 mm² (6 AWG) copper. Both ends of the ground wire should be sealed with an
appropriate anti-oxidation compound.
5. A separate bonding wire of the same size as specified in Step 4 above should be connected between the
ground lug at the left side of the power supply chassis and earth ground where such connection enters
the external system enclosure.
4.3 Placement in the Enclosure
This power supply has been designed primarily for use within a cabinet or enclosure offering protection from
outdoor weather, entry of excessive dust, dirt or moisture, and from unauthorized contact by untrained personnel.
If used in a controlled environment, the power supply may be located within an indoor equipment cabinet or may
be mounted on a rack shelf.
The power supply should be mounted on a ventilated shelf that allows free air circulation, especially through the
right and left side panels of the power supply cabinet. Clearance of at least 51 mm or 2 inches must be
maintained around all surfaces of this power supply for unobstructed airflow. Temperature of the air entering the
power supply should not exceed 50°C (120° F).
