HP 2995 CONNECTION, CAUTION, Step 4 – Preliminary Setup

CONNECTION

CAUTION

The PCB inside the inverter enclosure is vulnerable to static electrical charges. Avoid contact with the PCB.

Choose an appropriate power source with correct voltage settings for the specification of the AC inverter.

Do not use a separate device between control and motor to switch motor ON or OFF during operation.

Step 4 – Preliminary Setup

Figure 4 - Inside of control, showing location of jumpers and fuses.

BASE FREQUENCY JUMPER - Model 2995 is factory set to operate 60 Hz and 50/60 Hz motors. For 50 Hz motors, remove jumper J1 on the lower printed circuit board. When the control is set for 50 Hz operation, the DECEL/B trimpot will automatically change to adjustable boost. The control can also operate 60 Hz and 50/60 Hz motors (not 50 Hz motors) in an over speed mode by moving the jumper to the 120 Hz position.
