Troubleshooting & FAQ

10. Can I make my own repairs to unit?

During the warranty period, the unit can only be repaired by Tesla Industries for the warranty to remain in effect. Regardless,
we strongly recommend allowing Tesla to repair any unit as we will analyze the complete system and re-calibrate it.

11. What type of maintenance does the DC Power Supply require?

Although the systems are maintenance free, please keep the vent areas clean and free of debris. Keep units in a well
ventilated area. Keep the unit in a protected environment when not in use (maintenance facility, shed).

6.2 - Basic Usage/Operation Questions

1. What’s the best position to place the unit for use vertical or horizontal?

Preferred position is horizontal for stability and airow considerations.

2. How do I check the status of the Available Power?

The “Available Power” LED Indicator provides a way for the user to visually see the amount of available power that the TI50A
can supply. This lets the operator know if there is enough power to perform ground maintenance. For more information see
Section 2.12.

3. Why is the cooling fan always running when I am plugged into AC power?

Constant cooling fan operation ensures proper and consistent ventilation of the unit.

4. Why does the cooling fan slow down?

Cooling fan rpm varies for better temperature regulation.

5. What do I do if a circuit breaker trips?

The AC input circuit breakers are located above the AC Input Connector. When the circuit breaker has been tripped,

either of the red buttons will pop out. In the event that the breaker trips:

1. Disconnect the ac and dc connectors. (Unplug ac line cord on military unit.)

2. Wait for a minimum of 60 seconds.

3. Reset breaker(s) by pressing red button(s).

4. Reconnect ac and dc connections to the unit. (Plug in ac line cord on military unit.)

The unit should power up automatically. If the breaker continues to trip, return the unit to Tesla Industries for repair.
