VOLTAGE OUTPUTS
External loads are connected to the generator via the
UVWO voltage outputs. Various output voltages can be
accessed either by terminal lugs, buss bars or camloks.
Voltages are dependent on the position of either the voltage
selector switch or voltage change-over board depending
on type of generator.

Figure 25. Buss Bar Voltage Outputs
When attaching terminal rings with wires to the output
terminal panel, always make sure the wires are in a fully
vertical position. NEVER attached the wires at an angle.
The possibility exist that the wires could touch each other,
thus causing a short. This condition could cause severe
damage to the equipment and bodily harm.
DO NOT over tighten the nuts and bolts that secure the wire
terminals to the output terminal panel. Reference Table 9
for the correct torque specication.
NOTICE
DCA-400 model generators and below use terminal
lugs for the UVWO voltage output as referenced in
Figure 24.
DCA-600 model generators and above utilize buss
bars (for the UVWO voltage output as referenced
Figure 25.
Camloks are available as an option on most MQ Power
generators.
