Pre-Installation Instructions
Installation must be in accordance with the following steps and must be
carried out by competent personnel. The DriveGuard Safe Torque Off option
is intended to be part of the safety related control system of a machine. Before
installation, a risk assessment should be performed that compares the
DriveGuard Safe Torque Off option specifications and all foreseeable
operational and environmental characteristics of the machine to which it is to
be fitted.
In no case should be DriveGuard Safe Torque Off option be used in a
PowerFlex 40P or PowerFlex 70 drive where the maximum surrounding air
temperature, shock, or vibration specifications of the drive are exceeded.
A safety analysis of the machine section controlled by the drive is required to
determine how often the safety function should be tested for proper
operation during the life of the machine.
