• Additionally, a Double Pole Circuit Breaker of the circuit rating must be used. The Charging
Unit has a built in GFCI protection; do not provide any additional GFCI protection upstream of
the charging unit.
• The Charging Stations can connect (plug into) a Standard NEMA 6-50 or 14-50 Receptacle or
the unit can be hardwired
Caution:
The service wiring in this section are specific to North America only. Before installing
the Charging Station, identify the type of utility service connection available onsite. If
you are unsure about the type of connection available at the service panel, contact
your utility service provider.
2.1.2 Grounding Instructions
2.1.3 Adjusting the Charging Station Maximum Current Output
Setting (Optional)
The charging station must be implemented equipment grounding through a permanent
wiring system or an equipment grounding conductor. Use a cable with a dedicated grounding
conductor connected to the equipment ground terminal block.
• Do not touch live electrical parts.
• Incorrect connections may cause electric shock.
• Disconnect the power supply to the charging station and verify no power is present before
installing, adjusting, or repairing the charging station. Failure to do so may result in physical
injury or damage to the power supply system and the charging station.
• Electrical Power MUST remain OFF and DISCONNECTED before setting or changing the DIP
switch. A non-conductive object MUST be used to adjust the DIP switch settings, failure to do
so may result in risk of electrical shock and damage to the equipment.
The GRIZZL-E ™ charging station product features the ability to adjust the maximum Charging
Station current output to allow the use of a 50A, 40, 30A, or 20A Dedicated Circuit as follows:
Warning: risk of electric shock
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
