· DB resistor wiring for 7.5 - 10HP Inverter
DB resistor terminal Terminal description
B1, B2 Connect the DB Resistor to Inverter terminal B1, B2.
TH1, TH2
Thermal sensors provided with the DB resistor.
P1 is ON (TH1-TH2 Shorted) at normal (ambient temp) and P1 is OFF (TH1-TH2
Open) at overheated status. Connect the thermal sensor to one of the multi-function
input (P1, P2 or P3, I/O 12-14 setting: Ext Trip-B).
