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 inverter 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 inverter.
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 inverter'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 inverter must be returned. Refer to "Routine
Maintenance and Repair".
