The DC supply source is to be located within the same premises as this equipment.
There shall be no switching or disconnecting devices in the grounded circuit conductor
between the DC source and the point of connection of the grounding electrode
conductor.
CAUTION
DC Unit Grounding: Before connecting the product to the power line,
make sure that the protective ground terminal of the device is
connected to the safety ground conductor of the mains power cord.
The mains plug should only be inserted in a socket outlet provided
with a connected safety ground. The protective action must not be
negated by use of an extension cord (power cable) without a
protective conductor (grounding). Any interruption of the protective
(grounding) conductor or disconnection of the protective ground
terminal can make the device unsafe to use. Intentional interruption
is prohibited.
This equipment has a connection between the earthed conductor of
the DC supply circuit and the earthing conductor.
Grounding
All NetEnforcer equipment has a connection between the grounded conductor of the DC
supply circuit and the grounding conductor.
Connect to a reliably grounded SELV source. Grounding is achieved through
connection of the power entry module grounding terminal to one power port of the
terminal block by min. No. 14 AWG green/yellow conductor.
This equipment shall be connected directly to the DC supply system grounding
electrode conductor or to a bonding jumper from grounding terminal bar or bus to
which the DC supply system grounding electrode is connected. When connecting the
supply wires to the DC main supply, the earth conductor will be connected first and
disconnected last.
This equipment shall be located in the same immediate area (such as, adjacent cabinets
or any other equipment that has a connection between the grounded conductor of the
same DC supply circuit and the grounding conductor, and also the point of grounding of
the DC system. The DC system shall not be grounded elsewhere.
