• During transport, screws in terminal block may become loose due to handling and vibrations. Check the
connections and tightened the screw if necessary.
• Ensure the voltage supply is within the required specification 230VAC (-6%/+10%) .
• Cable size recommendation selected in accordance to maximum conductor temperature of 75°C with wiring
enclosed in air.
• Suggested minimum cable size should be used as a guide only, refer to the latest edition of the AS/NZS 3000
