Installing HiPath 3800
4.2.4.4 Grounding the System
Ground the system as described.
Grounding: Inspection and Implementation
Preliminary Inspection of the 19-Inch Cabinet:
Is the 19-inch cabinet grounded
by a separate
ground conduc-
tor (green/yellow)?
The 19-inch cabinet must be grounded by a sepa-
rate ground conductor (green/yellow).
Danger
If your personnel are not qualified to work on the
low-voltage network (230 Vac), you must hire a li-
censed electrician to install the ground.
Does the 19-inch cabinet have
a
potential equalization bus at
which the HiPath 3800 can be
grounded as shown in Figure 4-
13 ?
A potential equalization bus must be installed in
the 19-inch cabinet and connected to the ground
conductor.
Danger
If your personnel are not qualified to work on the
low-voltage network (230 Vac), you must hire a li-
censed electrician to install the ground.
If you answer “Yes” to both questions, the system (system cabinets, patch panels) may be
grounded as described below.

Danger
Each HiPath 3800 system cabinet and any patch panel (S30807-K6143-X) that may
be installed must be grounded as shown in Figure 4-13 by a separate ground con-
ductor (minimum cross-section = 2.5 mm
2
). Make sure that the ground conductor is
securely installed and strain-relieved.
If external factors can impact on the ground conductor and if protected installation is
not possible, the ground conductor must have a minimum cross-section of 4 mm
2
.
Please note:
The 19-inch cabinet’s potential equalization bus may only be used if it is grounded
by a separate ground conductor.
Failure to follow these instructions can result in electrical shock.
