Adjustable Maximum Current Output to Support Multiple Circuit Ratings

The GRIZZL-E ™ charging station product features the ability to adjust the maximum Charging
Station current output to allow the use of a 50A, 40A, 30A, or 20A Dedicated Circuit as follows:

50A Circuit Rating: To support 40A (9.6 kW) maximum Charging Station output

40A Circuit Rating: To support 32A (7.68 kW) maximum Charging Station output

30A Circuit Rating: To support 24A (5.76 kW) maximum Charging Station output

20A Circuit Rating: To support 16A (3.84 kW) maximum Charging Station output

Notes on Circuit Requirements and Amperage settings:

• The Charging Station Default Factory Maximum Current Output Setting is 40A (9.6 kW) for
use with a 50A Circuit Rating – Please refer to Adjusting Maximum Current Output on page
12 when using a 40A or 30A or 20A Circuit Rating.

5

• To obtain the fastest charging capability of 40A, a 50A Circuit Rating must be used.

• The Circuit must be a DEDICATED CIRCUIT 208-240 VAC, 50-60 Hz, Single Phase.

• Per only 80% of the circuit rated load may be utilized, hence the higher Circuit Ratings
Requirement relative to maximum Charging Station output.

The ability to utilize alternate circuit ratings can be beneficial in the instance the location
of installation cannot support a 50A circuit, or in instance where an existing 40A
or 30A or 20A dedicated circuit is already installed.

Security and Tamper Feature

In addition to the pin that secures the GRIZZL-E ™ charging station to the wall mount bracket
(Refer to Section 2.3, Paragraph 3., Installing the Charging Station), if desired, a feature is
included as part of the charging station and wall mount bracket to replace provided pin with
the coupler lock with the minimum parameters:
Length: 90mm, Diameter: 7mm
for added security and tamper benefits.

Self-Monitoring and Recovery | Power Outage Recovery

When a charging session is interrupted due to a temporary error condition, the charging
station will automatically restart charging when the cause of the temporary error condition
returns to normal. The status indicator lights remain flashing RED until the error condition
is resolved.

• Temporary error condition include: Overcurrent, Overvoltage, Undervoltage, Missing diode,
Ground fault and Over Temperature.

• For Over Current (OC) conditions: The charging session will be stopped while OC occurs.
After recovery from OC for 30 seconds, the charging station will automatically restart charging
for 4 times.

• When charging session stopped due to Ground Fault (GFCI) trip, the charging station will
try to restart after 15 minutes for 4 times. After 4 times, the charging station buzzer will stay
on continuously, and status indicator will stay RED. The user should plug-out and plug-in the
power cable of the charging station.
