POWER REQUIREMENTS AND INSTALLATION
The following power requirements and instructions are for North America, Japan, and
locations using 60 Hz power. All other locations should refer to the instructions
found in Appendix B.
The eddy current brake 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 brake. Connecting the brake to the incorrect
voltage will void the brake warranty. Contact Dynojet with any questions.
The eddy current brake requires a dedicated wall receptacle which must be wired for
operation and is included with the brake or may be shipped in advanced in a separate
package. The brake 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
acceptable, but performance of the eddy current brake 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 brake in North American or Japan and the brake is
not equipped with twist lock four wire grounded plug, contact Dynojet before
attempting to connect the brake.
Local and national electrical codes require a grounded receptacle box.
• This circuit should have a dedicated 30A double pole circuit breaker.
• The brake should be the only device connected to this circuit.
I NSTALLING THE W ALL R ECEPTACLE
The wall receptacle is included with your brake 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
connection and a ground. The neutral connection is required to split the 240 volt into
two 120 volt connections internal to the dyno.
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 green grounding screw.
