Power Supply
Electrical Safety
Warning:
Before removing any covers or performing maintenance repair and service, isolate
from electrical supply by removing mains plug. Where mains supply is required during these
activities, only competent persons should perform the work.
Check that the power supply is compatible with the requirements stated on the label and
connect in accordance with IEE regulations or to local requirements. It is advised that this
machine be connected via a residual current device (not supplied), and it should operate if
earth leakage current exceeds 0.03 amps.
It is recommended that the mains cable be connected to a no-volts switch so that in the
event of a mains failure, the apparatus can only be re-started if the no-volt switch has been
reset.
The power cable is coded as follows:
Brown Wire
L
Live or power
Blue Wire
N
Neutral
Green / Yellow Wire
E
Earth or Ground
Portable Appliance Tests (PAT)
An electrical safety test label is fitted (usually adjacent to the mains input socket).
Organizations have an obligation to ensure equipment is maintained and is safe for use.
Regular PAT testing is one means of ensuring equipment continues to be electrically safe.
DO NOT FLASH TEST ELECTRONIC EQUIPMENT.
If in doubt as to the most suitable connection point (which will usually be an earth
stud or an external earth connection) contact the ELE Service Department for
assistance.
