lug can damage the PTX1000.
Before connecting the PTX1000 to earth ground, review the following information:
A protective earthing terminal bracket is required for connecting the PTX1000 to earth
ground. This two-holed bracket attaches on the side of the PTX1000 chassis through
the mounting rail and provides a protective earthing terminal for the device. The
grounding points require two #10-32 UNF screws and washers. The grounding points
are spaced at 0.63 in. (16 mm).
The grounding lug required is a Panduit LCD6-14BH-L or equivalent (not provided).
The grounding lug accommodates 14–6 AWG (2–13.3 mm²) stranded wire.
The grounding cable that you provide for a PTX1000 must be the same size or heavier
than the input wire of each power supply. Minimum recommendations are 8 AWG
(8.4 mm²) stranded wire, 60° C wire, or as permitted by local code.

When planning the site for a PTX1000 installation, you must allow sufficient clearance
around the installed chassis (see

Figure 23: Clearance Requirements for Airflow and Hardware Maintenance for a PTX1000

Follow these guidelines:
For the cooling system to function properly, the airflow around the chassis must be
unrestricted. See "PTX1000 Cooling System Description" on page 34
information about the airflow through the chassis.
If you are mounting a PTX1000 in a rack with other equipment, ensure that the exhaust
from other equipment does not blow into the intake vents of the chassis.
