Lincoln Electric IM511-D manual Standby Power Connections

Most 1.5 HP 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 1.5HP 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 2HP can be run provided the receptacle rating as previously stated is not exceeded. This may necessitate 230V operation only.

It must be noted that the above auxiliary power ratings are with no welding load. Simultaneous welding and power loads are permitted by the following table. The permissible currents shown assume that current is being drawn from either the 115 volt or 230 volt supply (not both at the same time).

NOTE: Voltage and permissible watts decrease as “CONTROL” is adjusted to settings less than

10.It is recommended that at settings less than 10, only incandescent lighting loads be connected to the auxiliary power receptacles.

Standby Power Connections

The Ranger 9 is suitable for temporary, standby or emergency power using the engine manufacturer's recommended maintenance schedule.

The Ranger 9 can be permanently installed as a standby power unit for 230 volt, 3-wire, 40 ampere service. Connections must be made by a licensed electrician who can determine how the 115/230 volt power can be adapted to the particular installation and comply with all applicable electrical codes. The following information can be used as a guide by the electrician for most applications (refer also to the Premises Wiring diagram shown).

IMPORTANT: When the Ranger 9 is connected to a 230 volt, 3-wire line, the unit should be operated with the idler switch in the “HIGH” idle position to avoid load sensing problems. If the machine is set for automatic idle, the 230 volt circuit will sense loads and cause the engine to accelerate to high idle. However, since only one line of the circuit senses current, 115 volt power drawn from only one line to neutral may result in the engine not going to high idle.

1.Install the double pole, double throw switch between the power company meter and the premises disconnect.

Switch rating must be the same or greater than the customer’s premises disconnect and service overcurrent protection.
