WARNING – The CTR Must Be Connected Correctly.

1) The CT protector (model: CTR) included in the product 

package must be used for safe operations.  Turning on the 

CT without connecting the CTR opens the circuit and is 

potentially dangerous.

2) The CTR is not interchangeable with another.  Be sure to 

match the serial No. of the CTR to that of the converter.

3) Connect the CTR’s wires (C, D) and metal legs (A, B) to 

the corresponding terminals of the installation base as 

indicated in the figure to the right.  The metal legs (A, B) 

are to be secured at the base terminals together with the 

output wires from the CT.  Wrong connection may cause 

abnormally high temperature in the unit which could 

lead a fire in the worst cases.

4) Confirm the right connection of the CTR again before 

turning on the CT.
