Grounding Requirements

The voltage of either line, relative to ground, must not fall below 80 volts or a Floating Line Connection error occurs (see
page 6-3). Because the voltage of either line relative to ground must not be allowed to fl uctuate, use only center­grounded systems. Neutral is not used to power the station but must be properly connected to ground, at the panel or
transformer, to provide the necessary voltage reference relative to ground.

Connect to these systems

In a wye system, connect the station to ANY two lines, as shown below.

In a delta system, connect the station to a center-tapped secondary only, where the center tap is bonded and the station is
connected to L1 and L3. This allows voltages to remain constant regardless of other loads that may be using the lines.

Do not connect to these systems

Do not connect ChargePoint stations to the following types of power sources:

• 120/208 VAC 3 phase wye, ungrounded

• 120/240 VAC 3 phase delta, corner-grounded

• Any system where the center point of the AC power source is not grounded

Step 4: Install Main Body

To install the main body:

• Align the notches on the rubber bumper with the
front mounting nuts, then slide it all the way down
the pole until it is fl ush with the base plate. This
prevents any rocking motion between the main body
and the base plate.

• Slide the body over the mounting pole.

• Re-tighten the screws you loosened in Step 2 to
approximately 80 in-lbs using a 3/8” socket wrench.

IMPORTANT: Ensure the body is fi rmly aligned to
the bottom surface and that no movement (rocking) can
take place, even when signifi cant pressure is applied.

has built-in GFCI protection.

• In areas with frequent thunder storms, add surge

protection at the service panel for all circuits.

• Use new circuit breakers only. Used breakers can

damage equipment and introduce the potential for an
electrical fi re.

• Ensure all power and ground connections, especially

those at the breaker and buss bar, are clean and tight.
Remove all oxide from all conductors and terminals
before connecting wiring.

Installing a Bollard Mount

Step 8: Check Voltages

• Turn power ON.

• Using a solenoid type voltage tester, check that the
voltages at the charging station’s terminal block are
as follows:

Measure Between Volts

L1 and L2 208/240

GND and L1 120

GND and L2 120

If the voltages are not as expected, ensure that the
wiring has been properly connected as describing
on the previous page. For detailed wiring diagrams
and grounding requirements, see pages 1-4
to 1-6.

Before continuing, resolve any wiring issues and
ensure that voltages are as expected.

• Turn power OFF.

Installing a Wall Mount

Step 2: Drill Holes in Wall

• The packing box for the brackets is used as a

template for drilling the wall holes. Tear the packing
box along the perforation to allow it to lay fl at.

• Place the template against the wall. As described on

the package insert, align the top where indicated, 49”
above the fl oor or ground. Ensure that the template
is level and the side of the packaging insert is plumb.
Mark the four mounting holes.

• Drill four holes in the wall at the marked locations.

NOTE:

• If mounting to a hollow wall, bridge at least two

studs using a 1 5/8” channel strut. For wood studs,
use 3/8” (9.5 mm) lag bolts that are long enough to
penetrate at least 2 1/2” into the stud. Then mount
the supplied brackets to the channel strut using 3/8­16 x 1” long bolts, 3/8 ID x 13/16” OD washers, and
3/8-16 channel strut nuts.

• If mounting to a masonry wall, use 3/8” (9.5 mm)

expanding masonry fasteners.

• If mounting to a wood wall, use 3/8” (9.5 mm) x 3”

(76 mm) lag bolts.
