UNPACKING
Each Martin Audio WX3A controller is built to the highest standard and
thoroughly inspected before it leaves the factory. After unpacking the unit,
examine it carefully for any signs of transit damage and inform your dealer
if any such damage is found. It is suggested that you retain the original
packaging so that the unit can be repacked at a future date if necessary.
Please note that Martin Audio and its distributors cannot accept
responsibility for damage to any returned product through the use of non-
approved packaging.

MAINS CONNECTION
The WX3A is provided with an IEC 320 type mains receptacle. It is supplied
with a 2m mains lead terminated with a standard IEC 320 plug, which must
be connected as below:
GREEN/YELLOW
BROWN
BLUE
Mains voltage tolerance ± 10% on each setting.
Fuses type T semi delay 100-120V 500mA(L), 220-240V 250mA(L)
WARNING: The WX3A controller must always be operated with the
mains safety earth connected.
To change the mains voltage, remove the rectangular fuse cap and replace
it so that the arrow on the body of the rectangle indicates the correct
voltage. The earth terminal on the IEC connector is permanently
connected to the metal casing. The unit is supplied with the 0V electronic
reference ground taken to the case via an internal 'signal ground' lead and
space receptacle, which inserts a ground lift resistor when in the 'Earth Off'
position. To connect the 0V electronic reference direct to the chassis
ground, use a pair of pliers to pull off the space receptacle from the 'Earth
Off' position and push it onto the 0V spade terminal (marked Earth On, on
the PCB).
This equipment must be earthed.
!
It should not be necessary to remove any protective earth or signal cable
shield connections.
