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 for this
to be optimised, the amplifier should be mounted in a metal rack enclosure, which should have a
separate (technical) Earth. Alternatively a separate earth should be attached to the amplifier at the rear
rack mounting bracket.
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. 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.
When mounting the amplifier in a rack or enclosure, ensure that:-
1.
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.
2.
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.
3.
The rack unit has a separate earth connection (technical earth).
