V. Preparation For Use
A. Line Requirements
The CLF5000/PLL is designed to operate from a 208 VAC, three phase line. The system will still function
within specifications when the line voltage fluctuates between 195 volts and 225 volts. Voltages over the
recommended 208 VAC, however, reduce the safe performance margins designed into the system and
should be avoided. The system draws a maximum of 22 Amps per phase when used to drive a load of 50
ohms. Under conditions of mismatch, the amplifier could draw slightly more current.
B. Cooling Requirements
The ambient air temperature should not exceed 40
o
C. There should be enough room over the top of the
amplifier and along the sides to permit an unobstructed airflow through the unit. Water temperature should
not exceed 35
0
C, and should not fall below a temperature where excess condensation could develop within
the unit. Water volume should be at least 7.6 l/m (2 GPM) and pressure kept below 414 kPa (60 PSI).
C. Installation Requirements
Prior to energizing the RF output perform the following safety checks:
1. Confirm that an appropriate RF output cable is connected from the RF output connector of the
generator to the system head or load. The RF interlock cover must be securely in place to allow
operation of the unit.
2. Check all cooling system piping and fittings for possible leaks. The preferred method is to pressurize
the entire cooling system with air and observe any loss of pressure prior to exposing the system to
liquid flow. The minimum air pressure used for testing should be at least equal to the maximum rated
pressure of the system.
3. Confirm that the remote control cable attached to J1 on the rear of the unit is securely in place. This
cable completes the interlock circuit as well as supplies RF enable commands to the generator.
4. Assure that the AC power connection is securely in place.
5. Test the interlock circuit to confirm that it is functioning properly. The interlock may be interrupted via
the interlock switch (CB2) on the front panel of the generator. Confirm that the RF enable signal is
disabled at the remote interface to the generator when an interlock fault condition occurs. Confirm that
AC power in the generator is dropped when the interlock fault occurs. Confirm that the RF enable
signal is held disabled by the host system after the interlock fault is cleared until it is intentionally reset
by the operator.
6. Confirm that all applicable safety labeling is in place as required by the end user’s local fire department
jurisdiction and Occupational Health and Safety Administration (OSHA).
