Connecting the PTX5000 Grounding Cable
Tools and Parts Required to Ground the PTX5000
Gather the tools required to ground the PTX5000:
Grounding cable (which you must provide)
Grounding lug (depending on your configuration, 0-AWG or 4-AWG (21.2 mm2) cable lugs are supplied with DC PDUs, and can be used for grounding.)
M6 screws or UNC 1/4-20 screws
Electrostatic discharge (ESD) grounding wrist strap

Connecting the PTX5000 to Earth Ground
You ground the PTX5000 by attaching a grounding cable to the chassis. You must provide the grounding cable. Depending on your configuration, 0-AWG or 4-AWG (21.2 mm2) cable lugs are supplied with DC PDUs, and can be used for grounding. See PTX5000 Chassis Grounding Cable and Lug Specifications for more information. You must install the PTX5000 in a restricted-access location and ensure that the chassis is always properly grounded. The PTX5000 has a two-hole protective grounding terminal provided on the chassis. See Figure 1. Under all circumstances, use this grounding connection to ground the chassis. For AC-powered systems, you must also use the grounding wire in the AC power cord along with the two-hole grounding lug connection. This tested system meets or exceeds all applicable EMC regulatory requirements with the two-hole protective grounding terminal.
To ground the PTX5000 (see Figure 1):
- Connect the grounding cable to a proper earth ground.
- Verify that a licensed electrician has attached the cable lug provided with the PTX5000 to the grounding cable.
- Make sure that grounding surfaces are clean and brought to a bright finish before grounding connections are made.
- Place the grounding cable lug over the grounding points on the bottom rear of the chassis. The top pair is sized for M6 screws, and the bottom pair is sized for UNC 1/4-20 screws. You can use either pair of grounding points. UNC 1/4-20 screws are provided in the accessory kit.
- Secure the grounding cable lug to the grounding points, first with the washers, then with the screws.
- Verify that the grounding cabling is correct, that the grounding cable does not touch or block access to the PTX5000 components, and that it does not drape where people could trip on it.
