Introduction; Before You Begin; Grounding Instructions - ChargePoint Express 200 Installation Manual

Introduction

This document provides important instructions that must be followed when installing the CPE200.
IMPORTANT:
• The CPE200 must be installed and serviced by ChargePoint-certified installers only. Contact ChargePoint
to find out how to become a certified installer. If the CPE200 is installed by any person other than a
ChargePoint-certified installer, the CPE200 is not covered under warranty and ChargePoint is not
responsible for any malfunctions.
• Ensure that all connections comply with local codes and ordinances.
• Observe all local and national safety regulations.
• Observe local regulations regarding wiring different circuits in the same conduit. In general, all
conductors occupying the same conduit must have an insulation rating equal to at least the maximum
circuit voltage applied to any conductor within the conduit.
• The CPE200 must be connected to a circuit provided with appropriate branch circuit over-current
protection in accordance with the National Electrical Code, ANSI/NFPA 70 or CEC for Canada.

Before you begin

• Take the online training course to become a ChargePoint Certified Installer and get a login for ChargePoint.
If you do not complete this training, you will be unable to complete the installation process.
• Ensure that the appropriate wiring, circuit protection, and metering is in place at the installation location by
reviewing the specifications, wiring diagrams, and grounding requirements described in this chapter.
• Verify that the installation site has a load capacity sufficient to support the CPE200.
• Ensure that adequate CDMA (Verizon or Sprint) or GSM (AT&T, Rogers) cellular coverage is available at the
installation location. To ensure adequate signal strength in underground garages or other enclosed parking
structures, cellular repeaters may be required.
• Review the contents of this document to familiarize yourself with the installation steps.

Grounding instructions

The CPE200 must be connected to a grounded, metal, permanent wiring system. An equipment-grounding
conductor must be run with circuit conductors and connected to equipment-grounding terminal or lead on
battery charger.
An insulated grounding conductor that is identical in size, insulation material and thickness to the grounded and
ungrounded branch-circuit supply conductors except that it is green with or without one or more yellow stripes is
to be installed as part of the branch circuit that supplies the unit or system. This grounding conductor is to be
grounded to earth at the service equipment or, when supplied by a separately derived system, at the supply
transformer.
