Checking the Grounding
Procedure
Perform the tests in the table below to ensure that the system is properly grounded before star-
tup.
Step
1.
Check the ohmic resistance of the ground connection to
the system:
Perform measurement between the PE (protective
earth) on a socket in the internal installation (at the sys-
tem's installation site) and HiPath 3800.
Prerequisites:
HiPath 3800 is not yet connected to the low-voltage
●
network via the power cable.
The system's separate grounding is connected.
●
2.
Check the ohmic resistance between the individual sys-
tem parts (basic cabinet, expansion cabinet, main distri-
bution frame).
Prerequisite:
HiPath 3800 is not yet connected to the low-voltage net-
work via the power cable.
