Electrical Considerations
The Power Supply Box is a permanently connected equipment. The user must supply the power cord
from the facility to the electrical access panel on the side of the unit.
The user must punch a hole through the electrical access panel and install a user-supplied strain relief
for the power cord. The strain relief attaching to the electrical access panel must be sized appropriate-
ly for the user-supplied power cord.
Precautions for Correct Use
The main disconnect switch located on the electrical access panel controls current flow into the
Power Supply Box. When the switch is in the horizontal position, it is OFF and when it is in the
vertical position, it is ON.
The Power Supply Box input power is protected by 25 A rated circuit breakers.
When connecting the power cord to its mating connector on the Docking Target, ensure that the power
cord connector is seated completely and secured. The power cord must be placed behind the Docking
Target. It must be properly protected and must not pose any hazards to personnel or interfere with oth-
er equipment.
WARNING
• Charging Station strain reliefs and the power cords must be installed by a licensed
or appropriately certified electrician.
• If power cords lie on the ground, you must make sure that they are highly visible to
prevent tripping hazards and must be protected from physical damage with barriers
or covers.
WARNING
Improper installation or wiring misconfiguration of the Power Supply Box could result
in electrical shock hazard. You must ensure the safe and proper installation of the
Power Supply box in accordance with the applicable rules and regulations, and by
qualified personnel.
Other important electrical considerations are listed below.
• The minimum wire rating for user-supplied connections inside the electrical access panel and the
AC supply are 10 AWG / 600 V.
• Power is provided to several power supplies inside the Power Supply Box as 3 distinct phases de-
rived from a 3-phase input.
• The power supplies can withstand up to 305 VAC (nominal 277 VAC) on any given phase.
• Configuration depends on a 3-phase scheme and voltage.
• Earth ground is separate and always only connects to the ground distribution block.
• White wires are used to configure Delta or WYE input. The white wires might also jump to field neu-
tral via the neutral terminal block. All white jumper wires are provided with Power Supply Box.
• The neutral terminal block can be used to terminate the abandoned neutral wire or aid in neutral
jump to the AC input terminal block.
• All field phase wires must connect to the main disconnect switch
• 4 wire Delta (jumper configuration as Delta) supports 200 to 240 VAC.
• 5 wire WYE (jumper configuration as WYE) supports 380 to 480 VAC line to line.
• 5 wire WYE (jumper configuration as Delta) supports 200 to 277 VAC line to line.
Use the figures below to understand the 3-phase wiring configuration options.
