4.3.4.5 Grounding the System
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 3700 can be
grounded as shown in Figure 4-
76?
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 3700 system cabinet and each patch panel (S30807-K6143-X) must be
grounded as shown in Figure 4-76 by a separate ground conductor (minimum cross-
section = 2.5 mm
2
). Make sure that the ground conductor is securely installed and
strain-relieved.
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.
