This guide assumes that the appropriate wiring, conduit and circuit protection is in place at the
installation site. Review this entire document to understand the installation process before installing
the SemaConnectTM Charging Station.
Key Requirements
•Each EV charging station shall be on a dedicated electrical circuit.
•Each station shall be protected with a 40 Amp 2-pole common trip circuit breaker (non-
GFCI type).
•Each station is designed to draw a maximum of 30Amps.
•Each station can operate on either a 240V or 208V circuit.
•Each station requires three electrical supply wires (two hot, one ground, no neutral).
•All data communication is wireless, so there is no data cabling to install, but cellular
communication is required.
Wiring Diagram
Connect SemaConnectTM stations to any one of the power source as shown
•208 VAC three phase , Delta system, Center tap grounded (use only two phases)
•208 VAC three phase, Wye system (use only two phases)
•240 VAC single phase
In a delta system, connect the SemaConnectTM station only to a center-tapped grounded transformer
only as shown below. Connect the station to the side where ground is bonded (in figure C line A and
C). This allows voltages to remain constant regardless of other loads that may be using the lines.
Please do not connect to other type of power sources shown below.

Follow the same procedure for both Single and dual pedestal mount installation.
Anchor Plate Installtion Procedure
Step-1:- Install the circuit Breaker.
Caution-1:- After 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
electrical conduit through the form. Please make sure that the electrical conduit does not come in the
way of J-bolts, while installing anchor plate.
Step-3:- Place concrete into the form and smooth it out.
Figure-1
Step-4:- Attach all four anchor bolts (J bolts) and four sacrificial Bolt to the anchor plate (Figure-2).
Note-1:- Nut in the anchor plate should face downwards.
Note-2:- Do not remove the sacrificial bolt(supplied by the manufacturer) from the
anchor plate.

Note-3:- Make sure that only one thread is coming out of the top nut when J bolt is
assembled to anchor plate. If more thread is coming out of top nut then installer will face
problems while mounting pedestal and CMS.
Figure-2
Step-5:-Insert the anchor plate into the concrete. Recommend vibrating the concrete to eliminate
any air bubbles.
Note:- Anchor plate surface should be in level with the ground.
Figure-3
Step-6:- Smooth out the concrete around the anchor plate.
Note:- Continuously check for the anchor plate until concrete sets to make sure that
anchor plate does not sink into the concrete (Figure-3).
SemaConnect Single/Dual Pedestal Installtion Procedure
Step-7:- Once the concrete has set, remove the Sacrificial bolts (Figure-4) from the anchor plate.
Then place the pedestal on top of anchor plate and screw in four pedestal mounting screw(Figure-5).
Do not tighten it fully.
Note-1:- Make sure the electrical wire is passed through the pedestal.
Note-2:- Ensure that access panel is to your right, when seen from the front end.

Step-12:- Now Slide the head unit onto pedestal and attach it with four mounting screw(Figure-8).
Note:- Make sure that the wires are not pinched between pedestal and charging station
Step-13:- Connect three electrical supply wires.
Note:- Strictly adhere to the wire color codes to ensure proper installation(Green-Green).
And use wirenut and Insulation tape for safety
Step-14:- Carefully push the wire in and attach the access plate(Figure-9)
Step-15:- Power up Charging Station by turning on circuit breaker(s). Station will automatically
communicate with network and initialize itself (using cellular signal). Successful power-up is
indicated by a steady blue LED light and welcome message on LCD.
