Connecting the PTX1000 to Ground

72
To meet safety and electromagnetic interference (EMI) requirements and to ensure
proper operation, you must connect the chassis to earth ground before you connect it to
power. For installations that require a separate grounding conductor to the chassis, use
the protective earthing terminal on the PTX1000 chassis to connect to the earth ground.
NOTE: An AC-powered PTX1000 gains additional grounding when you plug
the power supply in the device into a grounded AC power outlet by using an
AC power cord appropriate for your geographical location. See
AC Power Cord Specifications" on page
CAUTION: Before you connect power to the PTX1000, a licensed electrician
must attach a cable lug to the grounding and power cables that you supply.
A cable with an incorrectly attached lug can damage the PTX1000 (for
example, by causing a short circuit).
NOTE: Mount the PTX1000 in the rack before attaching the grounding lug
to the PTX1000. See
Ensure that you have the following parts and tools available (none are provided):
Grounding cable—The grounding cable must be 8 AWG (8.4 mm²), minimum 90° C
wire, or as permitted by the local code.
Grounding lug for your grounding cable—The grounding lug required is a Panduit
LCD6-14BH-L or equivalent.
Two #10-32 UNF screws and washers.
Screwdriver appropriate for the #10-32 UNF screws.
To connect a grounding cable to the PTX1000:
Connect one end of the grounding cable to a proper site earth ground, such as the
1.
rack in which the PTX1000 is mounted.
Place the grounding lug attached to the grounding cable over the protective earthing
2.
terminal on the chassis (see
