Introduction The Go Power! Transfer Switch-30 amp (TS-30) provides automatic power switching between two separate 120 volt AC input sources, including power cords, onboard generators, or onboard inverters.
GPTS-30 ___________________________________________________________ 2. Installation READ AND FOLLOW ALL SAFETY INSTRUCTIONS 2.1 Disconnect Power Make sure the generator is off, the external power cord is unplugged, and the inverter, if any, is shut off. 2.2 Mounting Location The TS-30 mounting location may be on any interior surface where the unit will be out of direct weather. The chosen location must be accessible after installation is complete to facilitate future servicing.
GPTS-30 ___________________________________________________________ 2. Determine proper connections of wire conductors to electrical terminals. On 120 VAC wiring the ground wire is bare or green, the neutral wire is white, and the hot wire is black. 3. Strip the outer jacket from all of the incoming cables and strip insulation from all ends of the copper conductors. Insert cables through clamps in openings. Do not tighten cable clamps at this time. 4.
GPTS-30 ___________________________________________________________ 3. Connect output to panel to terminals 3 and 4 (on the wide end of the relay). The TS-30 is designed with a time delay module to provide generators a brief warm-up period before supplying the load. See Diagram 1. Diagram 1 – Typical Generator Power Cord Connection 2.5.2 Installation Between Inverter and Alternating Source (Configuration C) 1.
GPTS-30 ___________________________________________________________ These connections will allow any other supply to dominate the inverter, and the inverter output will pass through the normally closed contacts of the switch. This allows the inverter to operate only in the absence of the other power supplies, which is ideal for inverters. 2. Connect the inverter to terminals 7 and 8, and connect the other power supply to 5 and 6. Output terminals always remain the same.
GPTS-30 ___________________________________________________________ The TS-30 A can be installed between inverter (default) and a circuit panel supplied by a larger amp alternating power supply (dominant). 1. Connect the inverter to terminals 7 and 8. 2. Connect the 30-amp branch circuit to 5 and 6. 3. Connect the designated circuit panel to the output terminals.

The inverter should always be connected so that it is only selected in the absence of both the other supplies. 4. Troubleshooting 4.1 Low Voltage Low voltage is harmful to most appliances. Contactor-based transfer switches are also affected by low voltage; if the voltage level drops far enough the contactor points will “chatter”.
GPTS-30 ___________________________________________________________ override the chattering condition and the meter will have time to register the reduced voltage. If this condition exists, identify and correct the low voltage situation before proceeding further. 4.4 Physical Interference leads. Occasionally on these models, the wiring connections will get folded into the can in such a manner that the wiring will interfere with the physical operation of the relay.
GPTS-30 ___________________________________________________________ must be checked, disconnect the generator wires from the transfer switch and connect hi-pot test leads to the loose wires. Reconnect wires after testing. 8. If hi-pot test fails, there is a short in the system. The next step is to isolate the location of the short. Turn off the main breaker in panel and hi-pot test again. If the test still fails, the fault is between the switch and the panel. Test cord for shorted plug.
