Installing Your Amplifier: Electrical Considerations

The amplifier has been manufactured to comply with your local power supply requirements,
but before connecting the unit to the supply, ensure that the voltage (printed on the rear
panel) is correct.
The amplifier is fitted with an adjustable 100/120V to 220/240V tapped transformer according
to customer requirements. Please note that adjustment of mains operating voltage requires
other component changes and must be undertaken by qualified service personnel only.
Make sure power outlets conform to the power requirements listed on the back of the unit.
Damage caused by connecting to improper AC voltage is not covered by the warranty.
SAFETY WARNING
Where a MAINS plug or appliance coupler is used as the disconnect device, it should remain
readily operable.
Where the amplifier is mounted in a rack and permanently connected to the mains, then the
rack should be installed with a readily accessible connector or an ALL POLE circuit breaker
with 3mm breaking distances.
This unit is fitted with a 3-wire power cord.
For safety reasons,
THE EARTH LEAD SHOULD NOT BE DISCONNECTED IN ANY CIRCUMSTANCE.
If ground loops are encountered consult the section on connecting your amplifier on page 11.
The wiring colours are:
230V AREAS: EARTH = GREEN AND YELLOW
NEUTRAL = BLUE
LIVE = BROWN
DO NOT USE THE UNIT IF THE ELECTRICAL POWER CORD IS FRAYED OR BROKEN. The
power supply cords should be routed so that they are not likely to be walked on or pinched by
items placed upon or against them, paying particular attention to cords and plugs and the
point where they exit from the appliance.
ALWAYS OPERATE THE UNIT WITH THE AC GROUND WIRE CONNECTED TO THE ELECTRICAL
SYSTEM GROUND. Precautions should be taken so that the means of grounding of a piece of
equipment is not defeated.
DO NOT REMOVE THE LID. Removing the lid will expose you to potentially dangerous
voltages. There are no user serviceable parts inside.
ESD strikes to the unit's front panel that are in excess of 4000 volts may cause disturbance to
the status LEDs on the unit. This will not affect audio performance and will be corrected on
the next power up cycle.
