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.
