# Installation

The tool should, via its correct POWER FOCUS/drive unit, be connected to the mains, 230V/ 50Hz alternatively 115V/ 60Hz, single phase. See instructions for your POWER FOCUS/ drive unit.

Fitting of the tool cable:

- Security check that the cabletype is correct

- Align the cable connector using the two asymmetrically positioned heads on the connector to fit in the slots in the tool handle.

- Tighten the lock nut.

- Security check that the connection is correct by pulling, pushing and turning the cable connector (there should be no movement).

The tool has a built in electronic memory chip that will transmit the torque transducer calibration value and angle pulses to the POWER FOCUS/drive unit. Any changes made of these values in the POWER FOCUS while the tool is connected will be stored in the tool memory.
