GENERATOR READY KITOPTIONAL USE WITH A PORTABLE GENERATORAn added feature of the GUARDIAN Generator Ready Kit is the ability to hook up a GUARDIAN ULTRA SOURCE portable generator.Included in the kit is a 5 foot electrical power cord and a 5 foot DC signal harness. The power cord contains 4 wires (black & red),neutral (white) and ground (green) wires. At one end are the terminal connectors. At the other end is the male connector (NEMA14-50) which plugs into the GUARDIAN ULTRA SOURCE portable generator’s control panel. To install this option, insert theterminal wire end of the power cord into the bottom of the external connection box through the conduit clamp (not included) fromthe outside. Allow about an inch of the power cord insulation to enter beyond the clamp to theinside of the box. TIghten clamp securely. Attach ground wire (green) to the bottom of the boxusing the supplied ground screw and pre-drilled hole. Connect red, black and white wires eachto separate lug posts. Make sure hold down nuts are tightened securely. The 5 foot DC signalharness allows semi-automatic transfer switch operation. You simply attach the four-pin plug to itsmating plug within the external connection box. At the other end is a V-type connector that plugsinto the 12-volt DC receptacleon the portable generator control panel. Instructions for these itemsare detailed on the following page (Page 8).CAUTION: If you are connecting the 5 foot power cord after the 30 foot conduit has been connected inside of the externalconnection box you must match the black, red and white wires to the lugs of the wires previously placed.(For example: black to black; red to red, etc.) Failure to match wires may result in damage to generator and house wiring.5 FOOT DC SIGNAL HARNESSULTRA SOURCE PORTABLE GENERATOR CONTROL PANEL12 Volt DCReceptacleNEMA 14-50Receptacle50 AMP POWER PLUGEXTERNALCONNECTION BOX5 FOOT POWER CORDWITH PLUGLug PostsBring powercord throughhereGroundScrewNEMA14-50 Plug7

Insert the NEMA 14-50 plug (from the power cord thatyou have installed) into the mating receptacle on thegenerator control panel.3. Start the generator.4. Let the engine stabilize and warm up for a few minutes.5. Insert the V-type plug (on the DC signal harnessyou have connected within the external connectionbox) into the 12 volt DC receptacle on the generatorcontrol panel. The insertion of this plug will send asignal to the transfer switch to shift the contactor tothe standby position.8. Set the generator’s 50 amp circuit breaker to its’ ON(or closed) position to send the generator power tothe load center in the transfer switch.Choose a lamp or light fixture located in a frequentlyoccupied area of the house as a signal light to tellyou when utility power has returned. This lightshould be on a utility powered circuit only so itoperates independent of the generator.8TRANSFER BACK TO UTILITY POWER SOURCEWhen utility power has been restored, you will want totransfer back to that source and shut down the generator.This can be accomplished as follows:1. Set the generator’s 50 amp circuit breaker to its OFF(or open) position.2. Remove the V-type plug (on the DC signal harnessthat was connected within the external connectionbox) from the 12 volt DC receptacle on the generatorcontrol panel. The removal of this plug will send asignal to the transfer switch to shift the contactorback to the utility position and allow the circuits ofthe home to again be powered by the incoming utility.3. Let the engine run for a minute or two at no-load tostabilize the internal temperatures.4. Turn off the generator.After utilizing the 5 ft. electrical power cord and 5 ft. DC signalharness for operation with the GUARDIAN ULTRA SOURCEportable generator you must disconnect and remove them.Open the external connection box.
