Connections - Ford PRO NB 120 Series Installation Manual

DC Charger

Connections

This section details the input and output connections that must be performed in the equipment. There are
several factors that can influence the choice of cable, including the distance between the distribution board and
the charger, the maximum input current, and the installation mode.
NOTICE
The dimensioning of the cables must be checked by a qualified electrician. The installer is responsible
for the correct sizing and execution of the corresponding connections in accordance with the regulatory
requirements applicable in the country of installation.
To guarantee proper insulation, it is very important the cable diameter is within the tolerable range of
the cable gland. Make sure that there is no space between the cable and the cable gland to prevent water
or dust from entering the interior of the equipment.
The power cables and RJ45 connector must be inserted into the equipment without crimping the
terminal, or they will not be able to pass correctly through all the expected spaces. Forcing them could affect
the sealing of the equipment.
The cable terminals can be either single / standard or double / long crimp barrel length depending on the
requirements of the project. The installer must consider the bending radius of the input power connections when
performing the crimping.
The AC connection is composed of three phases, ground wire and the neutral wire. Both, the power supply
input/output, and the communication connections input/output will be introduced through one of the accesses
and will pass through their corresponding space in the internal cable entry plate to reach the connection panel.
Note: The equipment does not require auxiliary power supply input, because it includes an internal transformer.
