Before commencing the installation
• Disconnect the power supply of the device.
• Ensure that devices cannot be accidentally restarted.
• Verify isolation from the supply.
• Earth and short circuit.
• Cover or enclose neighbouring units that are live.
• Follow the engineering instructions (AWA) of the
device concerned.

• Deviations of the mains voltage from the rated value must
not exceed the tolerance limits given in the specifications,
otherwise this may cause malfunction and dangerous
operation.
