6.3 Electrical connection and terminals
Step 1 .
Open the housing of the Green Motion Building EV charger. Refer to Section 10 of this manual for detailed
instructions.
Step 2 .
Insert the power supply cable through the cable gland on the bottom of the EV charger. Remove the cable
glands, if necessary.
Step 3 .
Connect the wires of the AC grid to the top or the bottom of the power supply terminals.
It is prohibited to connect the unit terminals to a circuit with a 3-phase IT grid configuration.
Before starting the connection operations, ensure that the external AC-line main switch is disconnected, and
circuit breakers are open.
Eaton recommends the use of the following equipment as protective devices.
In case of three phases, connect the phase (L1, L2, L3), neutral (N) and earth (PE) wires of the AC
(distribution) grid to the power supply terminal block in the Green Motion Building EV charger,
respecting the correct assignment:
•
Phase (L1)
L1 terminal
•
Phase (L2)
L2 terminal
•
Phase (L3)
L3 terminal
•
Neutral (N)
N terminal
•
Earth (PE)
PE terminal
Be careful not to reverse the phases with the neutral. If this happens, the system might malfunction.
In case of single phase, connect the phase (L1 OR L2 OR L3), neutral (N) and earth (PE) wires of the AC
(distribution) grid to the power supply terminal block, respecting the correct assignment:
•
Phase (L1) OR Phase (L2) OR Phase (L3)
L1 terminal
•
Neutral
(N)
N terminal
•
Earth
(PE)
PE terminal
