NSTALLATION
The Engine is designed to run from a single phase power source with one of its current
carrying conductors at or near ground earth ground potential ( the neutral conductor). Only
the line (live) conductor is fused for over-current protection. Systems that have both current
carrying conductors live with respect to ground , such as phase-to-phase in multi-phase
systems are not recommended as power sources.
It is recommended that both the Engine and Control surface are connected to the same
electrical supply or ring main which ideally should be regulated and smoothed. If the power
source is likely to be unexpectedly cut then both the units should be fed from a backed up
power source such as a UPS.
Mains connections should be fitted with the appropriate type of plug. See Section
“Mains
Plugs & Power Cords”
at the front of this Manual.
3.5.1 S
AFETY
Like all mains powered equipment, The console must be earthed. If hum problems
arise, or if earth loops are suspected, it is never correct or safe to remove the earth from
the unit having a three core mains input cable. Some other solution to break the earth loop
can always be found.
Power supply units contain lethal voltages. Always disconnect the mains from the
console before opening or removing covers.
3.5.2 M
AINS
INPUT
VOLTAGE
The power supply automatically adjusts for a wide range of input voltages.
Input voltages should be either between 90 and 132 volts or between 180 and 264 volts.
Despite the self adjusting input system, it is preferable for the mains to remain at a
constant value and to be free from transients.
3.5.3 M
AINS
CONNECTION
Do not replace the cable supplied with the power supply.
The mains cable contains three cores which are colour coded:
Brown
live
Blue
neutral
Green/yellow
earth
The earth connection must always be made.
