Appendix C: Guidance for Connection to Mains Supply
1. Ensure that the mains feed is from a clean AC supply with the following characteristics:-
Voltage Range
100V to 240V AC
Frequency
50/60Hz
It is highly recommended that this mains feed is via an appropriate Residual Current Circuit
Breaker, rated at 30mA trip current. This must comply with local regulations.
2. The mains input connectors are as follows:-
Device
Input Connector
Mating Cable Connector
Power Amplifier PA1
IEC C20
IEC C19
Control Unit CU1
IEC C14
IEC C13
These cables are available in specific versions for most countries.
3. If an un-terminated IEC connector lead is supplied with the equipment, the wires must be
wired accordingly:-
BROWN
LIVE
BLUE
NEUTRAL
GREEN/YELLOW
EARTH
4. It is essential that the control unit CU1 and the Power Amplifier PA1 are properly earthed at all
times.
5. It is recommended that the mains to each unit is supplied via an appropriate mains fuse:-
Power Amplifier PA1
13A
Control Unit CU1
13A
This is appropriate for the use over the whole supply voltage range.
6. This installation MUST be carried out by a trained, competent person.
7. Before initial switch-on, an appropriate earth bonding test should be performed to ensure a
robust earth connection.
8. To disconnect mains power, the mains supply cord must be removed from the rear panel
mains input connector.
