Working or touching the terminal with the power switched on may result in severe injury or death due to Electric Shock. Moreover, the instrument must be grounded before the power supply to the instrument is turned on. 4.
Notice • The terminal block of KT9 series is designed to be wired from the left side. The lead wire must be inserted from the left side of the terminal, and fastened with the terminal screw. • Dotted lines show options. • If A2 (option) and Heater burnout alarm (option) are applied together, use terminals 12-13 for A2, and 9-10 for the Heater burnout alarm.
[Heater burnout alarm output] (1) This alarm is not available for detecting 15 heater current under phase control. 16 (2) This alarm is not available for detecting 3-phase heater current. CT input terminals Power source CT (3) Use the current transformer (CT) provided, and pass one lead wire of the heater circuit into the hole of the CT. (4) When wiring, keep CT wire away from any AC source and load wire to avoid external interference. Heater (Fig. 4.
