120 V DUPLEX RECEPTACLES
The 120V auxiliary power receptacles should only be
used with three wire grounded type plugs or approved
double insulated tools with two wire plugs.
The current rating of any plug used with the system
must be at least equal to the current load through the
associated receptacle.
MOTOR STARTING
Most 1.5 hp AC single phase motors can be started if
there is no load on the motor or other load connected
to the machine, since the full load current rating of a
1.5 hp motor is approximately 20 amperes (10
amperes for 240 volt motors). The motor may be run
at full load when plugged into only one side of the
duplex receptacle. Larger motors through 2 hp can be
run provided the receptacle rating as previously stat-
ed is not exceeded. This may necessitate 240V oper-
ation only.

AUXILIARY POWER
The ZR-8 can provide up to 9,000 watts of 120/240
volts AC, single phase 60Hz power for continuous
use, and up to 10,500 watts of 120/240 volts AC, sin-
gle phase 60Hz power peak use. The front of the
machine includes three receptacles for connecting the
AC power plugs; one 50 amp 120/240 volt NEMA 14-
50R receptacle and two 20 amp 120 volt NEMA 5-20R
receptacles. Output voltage is /-10% at all
loads up to rated capacity. All auxiliary power is pro-
tected by cuircuit breakers.
Do not connect any plugs that connect to the
power receptacles in parallel.

Start the engine and set the
“

”
control switch to
the desired operating mode. Set the
“
CONTROL
”
to
10. Voltage is now correct at the receptacles for auxil-
iary power.
120/240 VOLT DUAL VOLTAGE RECEPTACLE
The 120/240 volt receptacle can supply up to 38 amps
of 240 volt power to a two wire circuit, up to 38 amps
of 120 volts power from each side of a three wire cir-
cuit (up to 76 amps total). Do not connect the 120 volt
circuits in parallel. Current sensing for the automatic
idle feature is only in one leg of the three wire circuit
as shown in the following column.
