Installation

Autobend 6

November, 1999

2-107

Gauge Cable

The gauge cable (harness) exits from the bottom of the AB6 power cabinet
and connects to the gauge as described in the following sections.

Warning

Failure to follow these guidelines may result in serious
injury:

•

Turn off the press brake.

•

Install the Out of Service tag.

•

Install the lockout device.

•

Do not interchange motor and tach wiring.

•

Do not reverse motor and tach positive and
negative terminals as sudden gauge
movement may result.

Contact Hurco’s Autobend Service Department with questions regarding
the wiring of these components.
