This guide assumes that the appropriate wiring, conduit, and circuit protection are in place
at the installation site. Review this entire document to ensure you understand the installation
process before installing the SemaConnect 620 Charging Station.
Key Electrical Requirements
Wiring Diagram
Each charging station shall be on a dedicated electrical circuit.
Each station shall be protected with a 40-amp two-pole common trip circuit breaker.
(non-GFCI type).
Each station is designed to draw a maximum of 30-amps.
Each station can operate on either a 240V or 208V circuit.
Each station requires three electrical supply wires (two hot, one ground, no neutral).
Note: Data communications are wireless,so there is no data cabling.
Connect the SemaConnect 620 station to any one of the power sources as shown:
208 VAC three phase, Delta system, center tap grounded
208 VAC three phase, Wye system, center tap grounded
240 VAC single phase, bonded neutral.
In a Delta system, connect the SemaConnect 620 station only to a center-tapped ground-
ed transformer as shown above. Connect the station to the side where the ground is
bonded (in gure 3, line B and C). This allows voltage to remain constant regardless of
other loads that may be using the lines. Please do not connect to any of the other types
of power sources shown below.

SemaConnect 620 Single- & Dual-Pedestal Mount Installation
Figure 1
Figure 2
Follow the same procedure for both single- and dual-pedestal mount installation.
Anchor Plate Installation into Concrete
Step 1: Install the circuit breaker.
Caution: After the circuit breaker is installed, make sure it’s turned off.
Step 2: Prepare the site and construct a concrete form (typical footprint: 24”x24”). Run the electri-
cal conduit through the form. Please make sure that the electrical
conduit does not get in the way of the J bolts when installing the anchor plate.
Step 3: Place the wet concrete into the form and smooth it out.
Step 4: Attach all four anchor bolts (J-bolts) and four sacricial bolts to the anchor
plate (Figure 2).
Note 1: The nuts in the anchor plate should
face downward.
Note 2: Make sure that only one thread is
coming out of the top nut when the J bolt is
assembled to the anchor plate. If more
thread is coming out of the top nut, then the
installer will face problems while mounting
the pedestal.

Step 5: Insert the anchor plate into the wet concrete.
Vibrate the concrete to get rid of any air bubbles.
Note: The anchor plate surface should provide a level surface for the
pedestal.
Step 6: Smooth out the concrete around the anchor plate.
Note: Make sure anchor plate sits on top of the concrete (Figure 3).
Step 7: Once the concrete has fully set, remove the sacricial bolts (Figure-4) from the anchor
plate. Then place the pedestal on top ofthe anchor plate and screw in four pedestal-mounting
screws (Figure 5). Do not tighten fully.
Note 1: Make sure the electrical wire is passed through the pedestal.
Note 2: Ensure that the access panel is to your right when its viewed from the front end.

Step 8: Align the pedestal for plumb with the help of a set screw on the pedestal
(Figure 4). Once the pedestal is level, fully tighten the pedestal-mounting screw.
Step 9: Loosen the set screws in the head unit(s) and attach the cable rack to the
charging station (Figure 5).
Step 10: Remove the access panel from the head unit.
Step 11: Place the J1172 in the holder and hang the cable in the cable rack
Step 12: Now slide the head unit onto the pedestal and attach it with four mounting
screws (Figure 6).
Note: Make sure that the wires are not crushed between the pedestal and charging
station.
Step 13: Connect the three electrical supply wires.
Note: Strctly adhere to the wire color codes to ensure proper installation (green-green). Make sure
to use wire nuts and insulation tape for safety.
Step 14: Carefully push the wires in and attach the access plate (Figure 7).

Step 15: Power up the charging station by turning on the circuit breaker(s).
The station will automatically communicate with the network and initialize
itself using a cellular signal. A successful power-up is indicated by a steady
blue LED light and welcome message on the LCD screen.
