P1: Voltage adjustment
P2: Droop adjustment².
P3: Stability - 2 adjustment.
P4: Stability - 1 adjustment.
P5: Under frequency adjustment.

8 TRIMPOTS ADJUSTMENT

P1: Rotating CW, voltage increases.
P2: Rotating CW, reactive compensation range increases.
P3: Rotating CW, dynamic response will be slower.
P4: Rotating CW, dynamic response will be slower.
P5: Rotating CW, U/F range increases and rotating CCW, it decreases.
NOTE
1. A potentiometer may be connected for fine voltage adjustment (5 k / 3 W) at terminals 6 and 7.
¹ Only for models TH4 E and TH4 PE.
