Hazards
DANGER! - Ignoring the following may result in injury
1. This equipment can endanger life by exposure to
rotating machinery and high voltages.
2. The equipment must be permanently earthed due to
the high earth leakage current, and the drive motor
must be connected to an appropriate safety earth.
3. Ensure all incoming supplies are isolated before
working on the equipment. Be aware that there may
be more than one supply connection to the drive.
4. There may still be dangerous voltages present at
power terminals (motor output, supply input phases,
DC bus and the brake, where fitted) when the motor is
at standstill or is stopped.
5. For measurements use only a meter to IEC 61010 (CAT III or
higher). Always begin using the highest range.
CAT I and CAT II meters must not be used on this product.
6. Allow at least 5 minutes for the drive's capacitors to discharge
to safe voltage levels (<50V). Use the specified meter capable
of measuring up to 1000V dc & ac rms to confirm that less
than 50V is present between all power terminals and between
power terminals and earth.
7. Unless otherwise stated, this product must NOT be dismantled.
In the event of a fault the drive must be returned. Refer to
"Routine Maintenance and Repair".
