If you are installing multiple PTP 820F units in a single rack, make sure to leave a space of 1RU after
every two PTP 820F units, as shown in the figure below. This restriction also applies to PTP 820F
units installed in proximity with third party units.
Grounding the PTP 820F
Connect a grounding wire first to the single-point stud shown in the figure below, and then to the
rack, using a single screw and two washers. Verify that the grounding resistance is 0-2 ohms.
Note
The grounding wire must be 16 AWG or thicker.
