Install DC Cables
The wiring on the DC side (the right side of the charging station) is only connected for Paired
installations. Do not connect this wiring for Standalone installations.
1.
Remove the plastic DC wiring cover on the right
side of the Express 250 by pressing on its sides
and pulling it outward.
2.
If not already done, label each end of each DC
conductor to aid installation as follows:
•
“Station 1 A+” on one end and “Station 2 B1+”
on the other end
•
“Station 1 A-” on one end and “Station 2 B1-”
on the other end
•
“Station 1 B1+” on one end and “Station 2 A+”
on the other end
•
“Station 1 B1-” on one end and “Station 2 A-”
on the other end
Important:
Disconnect numbers must be written in permanent marker. Normal ballpoint
pen ink does not stay legible on the label.
DANGER:
RISK OF SHOCK

Leave the power disconnected at the service panel to BOTH
Express 250 charging stations to be paired. Keep power off for both circuits until all cover
panels are correctly installed and the work scope is completed. FAILURE TO FOLLOW
THESE INSTRUCTIONS CAN RESULT IN SERIOUS INJURY OR LOSS OF LIFE.

The DC terminal blocks on the Express 250 can accept up to 120 mm
