Electrical Requirements For Battery Charging; Amperage And Breaker Parameters - Bosch Power Xpress Installation Instructions Manual

WARNING: The EVSE must be installed by a licensed
electrician in accordance with all national and
local electrical codes, ordinances, requirements
and all authorities having jurisdiction.
The conduit may extend up to 24 in. (61 cm) from ground level.
The wiring should extend 66 in. from the base mounting of the
bollard. A sweep is used to direct the circuit from the conduit to
the electric circuit from the service panel. The three types of
acceptable wire runs are:
• THWN rigid metal Schedule 40 or 80 conduit, buried 6 in. (15
cm) below ground level, or per local electrical code.
• THWN nonmetallic Schedule 40 or 80 conduit, buried 18 in.
(46 cm) below ground level, or per local electrical code.
• UF burial wire (ground solid), buried 24 in. (61 cm) below
ground level, or per local electrical code.
• THHN, THWN, or THWN-2 wires are recommended to allow
for proper space requirements inside the 1/2 in. flexible
conduit required in-side the bollard.

Parameters: Field Requirements
and Adjustments for EVSE
Installation (Not Required for 40
Amp Circuit Installation)
1. Unpack the EVSE.
NOTE: The EVSE has been factory set at 30 amp output for a 40
amp circuit. Proceed to "Standard Installation" if installing
on a 40 amp circuit. For all other amperages, complete
Steps 2 and 3 for EVSE adjustment.
2. Remove the domed cap from the current-adjustment
selector (positioned just above the reset button on the front
of the EVSE).

3. Using a small, flat-blade screwdriver, set the current-adjust-
ment selector to the applicable output current-limiting
setting as specified in "Figure 8. Current-Adjustment Set-
tings".
NOTE: Positions 6, 7, 8, 9, 0 are not used (X) and are non-opera-
tional. The EVSE will not function under these settings.
WARNING: The EVSE setting cannot exceed
ampacity ratings of field service wires or branch
circuit protectors.
WARNING: See "output" specification label located
on the side of the EVSE for maximum amperage
setting, per limitations of vehicle cable and
coupler.
NOTE: The EVSE must be de-rated to match line service
power limitations.
CAUTION: Use 75°C (600V) approved wire,
conductor temperature at 30°C ambient in wet or
dry locations.
