4. PA1 Power Amplifier Installation
4.1. Test Assembly Location and Ventilation Requirements
The PA1 amplifier must be positioned such that the front, sides and rear ventilation panels
are not obstructed to allow free movement of cooling air. The CU1 has no forced ventilation
requirements and can be sited close to the PA1.
Note: The HCS1 coil system should be positioned around 3m away from the amplifier to
reduce noise pick up from the amplifier.
Note: For optimum results the ambient temperature should not exceed the maximum
specified in the data sheet DS2613.
4.2. Connecting to the HCS1 System
The PA1 Power Amplifier connects to the HC1 or HC2 Helmholtz Coils and the CU1 Control Unit.
The HC1 or HC2 Helmholtz Coil connection to the PA1 Power Amplifier is to power the coils only.
See
Connecting to the CU1 Control Unit
for connecting to the CU1 Control Unit.
4.3. Connecting to the HC1 or HC2 Helmholtz Coils
The HC1 or HC2 Helmholtz Coils are fitted with a cable with a plug for connection to the PA1
Power Amplifier.
The PA1 Power Amplifier and the HC1 or HC2 must be connected before the amplifier power is
turned on. The supplied cable is plugged into the coil drive output socket on the rear of the PA1
Power Amplifier [13].
