ChargePoint Express 280 - Pairing Previously Installed Charging Stations

Pairing Previously Installed Charging Stations
If all site construction for paired charging is completed in advance, Express 280 stations can be initially
installed as Standalone and paired at a later date. In that case, follow these additional steps:
l
During initial site construction, install DC and communication conduit or ducting (as applicable by
region) in advance.
l
Extend side clearance at both DC conduit stub-up locations to 1.2 m (4 ft) to allow space for cable
pulling equipment.
l
Run a pull rope through the larger DC conduit before landing the charging stations. Do not pull DC
cable in advance, as it is too thick to hide inside the cover panels without risking damage or
unwanted electrical contact.
l
Install a fishing tape in the smaller communication conduit to assist with routing the Ethernet cable
later. If Ethernet is pulled in advance, leave 3.175 m (125 in) of wire above grade at each end.
l
Use duct seal compound to seal the ends of the DC and communications conduit stub-ups. Seal the
ends of the fishing tape to hang outside the conduit.
l
Install the cover panels and extrusions on the Express 280 stations over the stub-ups as normal.
By only connecting AC wiring (and shunt trip if applicable), each station can perform as a Standalone
station until the station owner is ready to pair them. At a later time, the stations can be paired by installing
DC conductors, connecting Ethernet communication, and performing a firmware update if required. Refer
to the Express 280 Installation Guide for further details.
Once two Express 280 are correctly paired, operation of both stations is inhibited if Ethernet connectivity is
lost or one station loses power. This is a safety feature to prevent one Paired station from accidentally
powering the other during maintenance.
WARNING: Do not connect DC power between the charging stations until both stations are ready
to complete the full pairing configuration. Station firmware updates are required to enable full
Paired behavior. Connecting power before the charging station is properly configured can create
a safety risk or can damage equipment.
WARNING: If service is performed on either Paired charging station, both stations must be
powered off at their AC disconnect switches and locked out/tagged out for safety.
