Installation and Operation
4.1
General
After unpacking, perform an initial inspection to ensure that the unit is in a good working order.
If the unit was damaged in shipment, notify the carrier immediately.
4.2
Temperature balance
In order to avoid condensation inside the device, the device itself must be able to adopt room
temperature. Please arrange the unpacked device at least 2 hours before usage.
4.3
Functional Test
Before installing the unit in a complete setup, a short test should be performed:
1.
Assure that the power switch is off.
2.
Disconnect all the signal and high voltage cables from the device.
3.
Set all of the SETPOINT-potentiometers to 10.0.
4.
Set all input selector switches to REM.
5.
Connect the unit to a grounded power outlet and turn the unit on.
6.
Connect a 50
:
BNC-termination impedance to the input INHIB at channel 1.
7.
Select channel 1 (CHANNEL).
8.
The voltage DVM should display about 0000 ±10;
the current DVM should display about 0000 ±10.
9.
Set the input selector switch to MAN.
10.
The voltage DVM should display about 500.0;
the current DVM should display about 0000 ±20.
11.
Turn the SETPOINT-potentiometer to 0.
12.
The output voltage changes from about +500 V to about -500 V.
13.
Repeat the test with all the other channels.
14.
Switch off the device.
4.4
Output connections
The outputs of the device supply a voltage of higher than 500 V. Connections to the load should
be provided only using connectors and cables with appropriate voltage rating.
Do not mate or unmate the output connector unless the device is switched off!
4.5
Ventilation Requirements
The HAR12 Amplifier Subrack may be used in rack mounted or bench top applications. In either
case, sufficient space must be allowed for cooling air to reach the ventilation inputs on the front
panels and for the fan exhaust air to exit from the rear of the unit.
The HAR2 may not be covered when in use. The unit must not be used without the provided
rubber-feet mounted to the bottom side.
Sufficient space for ventilation must be kept below and above the unit when the HAR2-W is
mounted.
