7 Electrical Connections
7.1 Requirements
Before making electrical connections, check the following:
– The mains power supply properties comply with EN 60204-1:2006+A1:2009 and the
power requirements of the unit.
– Mains power supply voltage tolerance should not exceed ± 10% with a maximum
phase difference of 3%.
When making an electrical installation, the installer must:
•
be qualified and licensed according to local and regional regulation.
•
Observe regulation relating to electrical power supply for the installation region
•
Observe the Low Voltage Directive 2014/35/EU
•
Provide potential equalisation
•
Equipped, and any connected component, must be wired with an earth
connection.
Unmade or partly made electrical connections have a high hazard of creating an
electrical potential on other materials. This can lead to death or serious injury.
When installing electrical connections:
•
Ensure all power supplies are disconnected including existing connections and
power to new connections to be made
•
Ensure any power supply cannot be inadvertently energised by 'locking' the
power supply.
NOTICE
The electrical wiring must be installed fully and correctly.
Failure to do so may result in damage to components and failure to operate.
•
Always refer to the 'unit-specific' wiring diagram.
•
Never connect multiple units to the same mains power supply.
Failure to follow these instructions can invalidate warranty.
NOTE!
We recommend installing power surge protection devices in areas of poor quality
electrical supply.
