Single Phase
• Connect a dedicated 120V (level I) or 208 – 240V (level II), over-current-protected service
to the two terminals, marked "L1" and "L2/N" in the figure. Connect the ground wire into
the smaller terminal marked "G".
• Critical setting: The three screw terminals for line power, above marked L1, L2/N, G,
must be torqued according to wire size, as shown in the table. Torque units are given in
inch-pounds and in Newton-meters.
• Terminals to the right should already be connected to the EV cable. If not, they must be
installed prior to operation and must be correctly torqued.
