Preliminary recommendations
Precautions
If the safety of personnel requires the prohibition of unwanted or unintended operation, electronic locking is performed by the
Altivar 71's Power Removal function.
This function requires the use of connection diagrams conforming to category 3 of standard EN 954-1 and safety integrity level 2
according to IEC/EN 61508.
The Power Removal function takes priority over any run command.
Read and understand the instructions in the Programming Manual.
CAUTION
INCOMPATIBLE LINE VOLTAGE
Before turning on and configuring the drive, ensure that the line voltage is compatible with the supply voltage range shown
on the drive nameplate. The drive may be damaged if the line voltage is not compatible.
Failure to follow this instruction can result in injury and/or equipment damage.
DANGER
UNINTENDED EQUIPMENT OPERATION
• Before turning on and configuring the Altivar 71, check that the PWR (POWER REMOVAL) input is deactivated (at state 0)
in order to prevent unintended operation.
• Before turning on the drive, or when exiting the configuration menus, check that the inputs assigned to the run command
are deactivated (at state 0) since they can cause the motor to start immediately.
Failure to follow these instructions will result in death or serious injury.
