Mains low-voltage power distribution room Charging pile pre-stage distribution box AC charging pile
Electric vehicle.
Charging pile input incoming line connection:
The device must be grounded. The firewire (L) neutral wire (N) must be tested with the test pencil. The
electric pen test is lit by the firewire (L), and then the L wire and the N wire are respectively connected to
the corresponding terminals!
Safety Warning: In order to ensure safe charging, the user must strictly follow the phase sequence of the
incoming terminal when wiring the input. At the same time, the charging pile with a rated current of 32A,
the incoming input line is not less than 6 square copper core wire; the charging pile with the rated current
is 16A, the incoming input line is not less than 4 square copper core wire. (After wiring is completed, put
it back into the lead wire of the column or protect it with a protective cover to prevent accidental exposure.)
The following safety regulations are observed when charging and wiring the charging pile:
No.
