Drainage
Ensure any site slopes, walls, or fencing do not trap water around the charging station installation
site. The system is only built to withstand 457.2 mm (18 in) of standing water.
Mounting Specifications
The Express 250 is installed on a concrete
pad. Details on how to prepare this pad are
described later in this guide.
All installations require four anchor bolts
(a). Standalone installations only require
the two conduit stub-ups on the left side,
for AC wiring and shunt trip wiring (b).
Paired installations also require the wiring
shown on the right: DC wiring and Ethernet
communication (c). For more detail, see
Conduit (page 21).
WARNING: If not installed correctly, the ChargePoint® charging station may pose a fall
hazard, leading to death, personal injury, or property damage. Always use the provided
Concrete Mounting Template or a ChargePoint-approved surface mounting solution to
install the ChargePoint® charging station and install in accordance with applicable codes
and standards using licensed professionals. Non-approved installation methods are
performed at the risk of the contractor and void the Limited Warranty.
WARNING: Exposing the ChargePoint® charging station to over 18 inches (457 mm) of
standing water could create an electrocution, shock, or fire hazard. Cut power to the
charging station if it has been exposed to standing water and contact ChargePoint before
the charging station is powered on.
Important: Although the Concrete Mounting Template was originally designed for six
anchor bolts, only the four corner anchor bolts are required for station stability. Newer
charging stations are designed to only use the four corner anchor bolts. If older sites were
already designed with six anchor bolts, removing the middle bolts is not required.
WARNING: If not installed correctly, the ChargePoint® charging station may pose a fall
hazard, leading to death, personal injury, or property damage. Always use the provided
Concrete Mounting Template shown pre-installed in the Introduction, or a ChargePoint-
approved surface mounting solution, to install the ChargePoint® charging station. Always
install in accordance with applicable codes and standards using licensed professionals.
Non-approved installation methods are performed at the risk of the contractor and void
the Limited One-Year Parts Exchange Warranty.
