AUXILIARY POWER

The ZR-10 can provide up to 9,000 watts of 115/230
volts AC, single phase 60Hz power, or 460 Volts,3
phase, 60 Hz for continuous use. The front of the
machine includes four receptacles for connecting the
AC power plugs; one 20 amp 460 volt 3 phase NEMA,
one 50 amp 115/230 volt NEMA 14-50R receptacle
and two 20 amp 115 volt NEMA 5-20R receptacles.
Do not use 3 phase power and single phase power
simultaneously.
CAUTION
Do not connect any plugs that connect to the power
receptacles in parallel.
------------------------------------------------------------------------
Start the engine and set the "IDLER" control switch to
the desired operating mode. Set the "CONTROL" to
10. Voltage is now correct at the receptacles for auxil-
iary power.
WARNING
A qualified person must make connections to plugs.
Connect each wire of the cord to the proper plug ter-
minal, especially ground.
115/230 Volt Dual Voltage Receptacle
The 115/230 volt receptacle can supply up to 39
amps of 230 volt power to a two wire circuit, up to 39
amps of 115 volts power from each side of a three
wire circuit (up to 78 amps total). Do not connect the
115 volt circuits in parallel.

115 V
115 V Duplex Receptacles
The 115V 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 (Refer to Tables I and II). Do
not attempt to connect power receptacles in parallel.
OPERATION
230 V
460 Volt 3 Phase Receptacle with Ground
The 460 volt receptacle can supply 12.5 amps of 3
phase power, or up to 15 amps of single phase power.
A NEMA plug L16-20P is required to use this recepta-
cle. The ground (GND) connection is connected to the
machine frame, it is NOT the neutral of the three
phase connection, and should under no circum-
stances be connected to the neutral of any 3 phase
load. Do not connect 460V 3 phase to premises
wiring.
If 460 volt single phase load is to be run, the X lead
must be one of the leads in the circuit in order for the
automatic idle to function. Using a NEMA plug L16-
20P, connect either X and Y or X and Z to the recep-
tacle, as well as the machine ground.
All auxiliary power is protected by circuit breakers with
the following values:
The 115V has 15 amp circuit breakers for each plug of
the duplex receptacle. The 230V has 50 amp circuit
breakers for each hot lead going the 230V receptacle.
The 460V 3 phase circuit breakers / switch has a 3
phase, 15 amp circuit breaker.

Ground Wire
Periodically check the ground wire at plugs, power
cords and auxiliary loads to ensure that the grounding
circuit is intact and connected.

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 230 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 stated
is not exceeded. This may necessitate 230V operation
only.
The 460 volt 3 phase output of the ZR-10 is capable
of running most 460VAC 3 phase motors up to 10HP.
A 10HP motor must be started with no load on the
motor and no other load connected to the machine,
since the full load current of a 10HP 460VAC 3 phase
motor is approximately 12.5 amps. Refer to the recon-
nect phase output to any load, the ground at the 3
phase receptacle is NOT the neutral of 3 phase con-
nection, and should under no circumstance be con-
nected to the neutral of any 3 phase load.
