 AC Torque Requirements: Torque all AC wiring connections to 16 in.-lbs. (1.8 Nm).
 DC Torque Requirements: Torque DC cable connections 100 in.-lbs. (11.3 Nm).
 DC Torque Requirements: Torque DC battery terminals to 30 ft.-lbs. (40.6 Nm).
2.2.1 Grounding Energizr
Energizr uses two separate electrical systems (AC and DC power). Therefore each electrical
system is required to be properly connected to a permanent “ground” or “earth” reference.
A system that is properly grounded limits the risk of electrical shock, reduces radio frequency
noise and minimizes excessive surge voltages induced by lightning.
To understand how the conductors in the electrical circuit will be connected to the system
ground, the following terms should be understood:
Grounded Conductor (GC): The wire/cable in the electrical system that normally carries current
(usually the AC neutral and/or the DC negative); and is intentionally connected or “bonded” to
the ground system. This wire or the ends of this wire should be colored white in a 120/240 VAC
system.
Equipment Grounding Conductor (EGC): A wire/cable that does not normally carry current and
is used to connect the exposed metal parts of equipment (that might be accidentally energized)
to the grounding electrode system or the grounded conductor. This wire, or the ends of this
wire, should be green or green with a yellow stripe; or this wire can be bare copper.
Grounding Electrode Conductor (GEC): The wire/cable that does not normally carry current and
connects the grounded conductor and/or the equipment grounding conductor to the grounding
electrode at the service equipment.
Grounding Electrode (GE): A ground rod or conducting element that establishes an electrical
connection to the earth or common ground reference.
System bonding jumper (SBJ): The connection between the grounded circuit conductor in the
electrical system and the equipment grounding conductor at a separately derived system.
