NORTH AMERICA, JAPAN, AND LOCATIONS USING 60 HZ POWER
The following power requirements and instructions are for North America, Japan, and
locations using 60 Hz power. Refer to “Excluding North America and Japan” on page
B-5 for all other locations.
The dyno requires a dedicated 240VAC single-phase power outlet rated for 30A for
proper operation.
Failure to follow these instructions could result in
personal injury or damage to the dyno.
Connecting the dyno to the incorrect
voltage will void the warranty. Contact Dynojet with any questions.
The dyno is equipped with a twenty-five foot power cord with a twist lock plug pre-
wired on the end.
The dedicated wall receptacle is a twist lock four wire grounded 30A NEMA L14-30
type and must be wired in accordance with local building codes and requirements. If
the facility does not have 120/240 volt single-phase power, and it does have 120/208
volt three-phase Y power, then it is acceptable to connect the four wire receptacle with
two of the three-phase lines, the neutral and the ground. With this arrangement, there
will only be 208 volts between line 1 and line 2 instead of 240 volts. This is acceptable,
but performance of the dyno will be reduced.
In no case shall all three-phase
lines be connected to the receptacle!
Installation may require a licensed
electrician and must conform to UL and NEC safety standards.
Note:
If you are installing your dyno in North American or Japan and the dyno is
not equipped with twist lock four wire grounded plug, contact Dynojet before
attempting to connect the dyno.
Local and national electrical codes require a grounded receptacle box.
• This circuit should have a dedicated 30A double pole circuit breaker.
• The dyno should be the only device connected to this circuit.

ECEPTACLE
The wall receptacle is included with your dyno and is shipped in a separate box or may
be shipped in advance in a separate package.
The wall receptacle is a single-phase 240 volt 30A dedicated circuit with a neutral
wire. The neutral wire is not used by the dyno, but needs to be connected to
terminal W.
The cable carrying the power to this receptacle should be ten gauge or larger. Check
with local building codes for the correct size.
1
Connect one of the 240V legs to the X terminal (gold colored screw).
2
Connect the other 240V leg to the Y terminal (gold colored screw).
3
Connect the neutral conductor to the W or WH terminal (silver screw).
4
Connect the ground conductor to the G terminal (green colored screw).
