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.

INSTALLATION EMC (RF Emissions)

The high frequency resonant converters in the E Series amplifiers have been designed to have

very low radio frequency (RF) emissions, which can cause interference with other equipment. In

order to reduce the influence of this, Power Amplifiers should be mounted in a dedicated metal

rack enclosure, which does not include equipment which may be sensitive to RF radiation, such as

radio microphone receivers.

INSTALLATION MECHANICAL

To ensure that this equipment performs to specification, it should be mounted in a suitable rack or

enclosure as described below. Like all high power amplifiers, it should be kept away from other

equipment which is sensitive to magnetic fields or RF radiation. Also, this amplifier may suffer a

substantial reduction in performance if it is subjected to, or mounted close to, equipment which

radiates high RF fields, such as power transmitters.

When mounting the amplifier in a rack or enclosure, ensure that:-

the rear of the unit is adequately supported. The brackets which are supplied fit standard 19

inch (483mm) rack mounting systems. THE FRONT PANEL IS NOT CAPABLE OF

SUPPORTING THE UNIT ON ITS OWN;

THERE IS ADEQUATE VENTILATION. The cooling fans suck cool air in through the front and

blow hot air out at the rear of the unit through the ventilating grills. IF THIS AIR IS NOT

ALLOWED TO ESCAPE, OVER-HEATING WILL OCCUR. Take care when mounting other

equipment in the same rack;

the rack unit has a separate earth connection (technical earth).
