Supply frequency has varied outside the TMS7's specified range. The manual's first action is: “1. Correct the cause of the frequency variations. 2. Check the three phase supply to the TMS7. Loss of all three phases is seen by the TMS7 as a 0Hz situation and may be the cause of a supply frequency trip. 3. Check the three phase supply to the TMS7 is connected to input terminals L1, L2, L3. Incorrect connection of the incoming supply to the output terminals T1, T2, T3 means there is no supply”

- CAUTIONCAUTION GROUNDING AND BRANCH CIRCUIT PROTECTION. It is the responsibility of the user or person installing the TMS7 to provide proper grounding and branch circuit protection according to the National Electric Code (NEC ®) and local codes . p. 3
What to do
- 1. Correct the cause of the frequency variations. 2. Check the three phase supply to the TMS7. Loss of all three phases is seen by the TMS7 as a 0Hz situation and may be the cause of a supply frequency trip. 3. Check the three phase supply to the TMS7 is connected to input terminals L1, L2, L3. Incorrect connection of the incoming supply to the output terminals T1, T2, T3 means there is no supply p. 29
