Quick Start and Safety Guide V 1.0 4 / 10
AMETEK CTS Solid State Amplifiers
WARNING: Do not touch the inner conductor of the RF-output connector.
High voltages can occur on the inner conductor of the RF output connector, or on cables or antennas connected to it. These can cause RF burns if touched.
.
WARNING : The Amplifier is required to be connected to a suitable ground point.
The amplifier conforms with IEC Safety class 1, meaning that it is provided with a protective grounding terminal. This is through the line supply cord to the centre pin of the power inlet connector. To maintain this protection, the line supply cord must always be connected to the source of line supply via a socket with a grounded contact. Do this before making connections to the RF-input or RFoutput connectors of the amplifier.
Without the protective ground connection, all parts of the amplifier constitute a potential shock hazard.
WARNING: Use the correct power cord.
Use only the line supply cord and connector specified for the amplifier. Use only a line supply cord that is in good condition.
WARNING: Do not remove covers or panels.
To avoid personal injury, do not operate the amplifier without the panels or covers in place.
WARNING: Do not operate in explosive atmospheres.
The amplifier provides no explosive protection from static discharges or arcing components. Do not operate the amplifier in an atmosphere of explosive gasses.
CAUTION: Avoid static discharges.
The RF input and output connections are static-sensitive and should not be subjected to static discharge.
CAUTION: Use the correct line supply source.
It is essential that the amplifier operates from a line supply source that does not apply voltages and frequencies between the line supply conductors (or between either line supply conductor and ground) that are outside the range detailed in the specification sheet.
CAUTION: Do not obstruct the circuit breaker.
Ensure that there are no obstructions that impair the operation of the rear panel line-supply circuit breaker(s).
CAUTION: Do not obstruct the airflow through the amplifier.
The cooling airflow is drawn in through the front and exhausted at the rear. If this airflow is obstructed, overheating of the amplifier may occur.
CAUTION: Do not operate the amplifier outside its specification.
This may cause the amplifier to malfunction or be damaged.
WARNING: Do not touch the exterior of the amplifier (rack mount version) when in use.
The top and side panels of the amplifier can get hot during use, especially on high power models.
CAUTION: Periodically replace the air-intake filters.
Operating the amplifier with the air filters dirty may cause the amplifier to overheat.
CAUTION: Exercise caution when lifting.
The appropriate lifting practices should be observed during transportation, installation, or removal of the amplifier from its mounting position.

AMETEK CTS Solid State Amplifiers
WARNING: Use the safety interlock facility within danger areas .
Any area where personnel may come into direct contact with high power RF, or be exposed to non-ionising radiation, should be designated as a danger area. A barrier should be established around any such area, with a switch in place when the barrier is broken. This switch can be linked to the safety interlock BNC connector on the rear of the amplifier, thus disabling the amplifier when the barrier is breached.
It is the responsibility of the operator to ensure that the working environment is safe. The ‘safety interlock’ feature is provided to assist the purchaser in establishing such a ‘safe’ area.

2. Installation
2.1 General
Solid State Amplifiers
CAUTION!
Exercise care when lifting.
Amplifier models that are very heavy have a caution label on the top cover. Appropriate lifting practices should be observed during transportation, installation, or removal of the amplifier from its mounting position. When mounted in a rack, the amplifier must not be supported by the front panel fixing holes alone. For easier installation and removal, we recommend that the amplifier is positioned with its top no more than 1.4 metres above ground level.
CAUTION : Do not support the whole weight of the amplifier with the front panel handles.
(See Section 12 of the main product manual)
These should only be used for sliding the amplifier in and out on the rack.
♦ Note: The amplifier may be lifted using the rear protection handles.
(See Section 12 of the main product manual).
The amplifier is designed to be mounted in a 19” fixed rack installation. When mounted in a rack, use a support tray-slider-assembly or rack sliders, especially for heavy amplifier models. See the section 12 of this manual for details of amplifier dimensions.
CAUTION: Do not obstruct the airflow through the amplifier.
At least 200mm clearance should be allowed behind the amplifier, so that air flow and connecting cables are not obstructed. An unobstructed area of at least 200mm should be allowed in front of the amplifier front panel airintakes.
CAUTION: Even though the ambient air temperature may be within the amplifier’s specification, the internal temperature may rise above operational limits if it is operated in direct sunlight.
The cooling airflow is drawn in through the front and exhausted at the rear. If this airflow is obstructed, overheating of the amplifier may occur. For correct amplifier operation, airflow through the unit must be maintained.
2.2 Connecting the line cord.
CAUTION: It is essential that the amplifier operates from a line source that does not apply voltages and frequencies between the line conductors (or between either line conductor and ground) that are outside the range detailed in the specification sheet.
CAUTION : Ensure that the line cord does not interfere with the operation of the rear panel line-input circuit breaker(s).
2.3 Connecting the chassis to a suitable ground connection.
To improve EMC immunity, bond the amplifier to a good ground with a conductor of 4 sq.mm or the equivalent earth braid, a ground post being provided for this purpose on the rear panel. Although it provides an extra measure of safety, this is NOT a protective earth connection. The protective earth is the ground pin on the line supply connector(s).
2.4 Connecting the RF cables
CAUTION : Ensure that the RF source is in, “RF OFF” mode when making connections.
Quick Start and Safety Guide V 1.0 7 / 10
AMETEK CTS Solid State Amplifiers
CAUTION: Ensure any cables and connectors mating with the RF input and RF output connectors are of 50-ohm impedance and are designed to handle the power at the frequencies generated by the amplifier. Although very similar, 75-ohm connectors must not be used.
Use cable with the lowest loss that is practical. The connectors should not be over-tightened, and any tightening instructions for the connector should be observed. Ensure that any bends in cables conform to the recommended minimum-bend-radius of those cables, especially where the cables enter the RF connectors.
2.5 Connecting the Safety interlock
WARNING:
Use the safety interlock facility within danger areas
.
If the amplifier is to be connected to an antenna, personnel may be exposed to non-ionising radiation. In such systems, the safety interlock function should used.
Connection (via the rear panel) is with a BNC-type connector. We recommend that shielded cable is used for all interlock connections to ensure EMC immunity.
The current in the safety-interlock circuit is less than 1mA, so cable with a low current capacity is suitable.
If you do not need this function, fit the supplied BNC shorting-link in place. Failure to do this will result in the amplifier latching in an “Interlock Open” status which switches the amplifier into standby mode.
2.6 Connecting an RF Load and Signal Generator
CAUTION: Ensure the RF output of the amplifier is connected to a suitable load that is rated for the frequency and peak RF output of the amplifier.
Do not switch the amplifier on without the RF output connected to a suitable 50ohm load. Switching the amplifier to an “RF on” state without a suitable load connected has the potential to damage the amplifier. The load must be rated for the frequency and maximum power the amplifier can generate. Any under rating in the load can lead to it being damaged with excessive power from the amplifier.
The selection of the load is the responsibility of the customer. The load can vary in type though it is important to note if the load is a poor match this will affect the amplifiers ability to deliver full power.
2.7 Line supply input connector
The Amplifier power supply is equipped with an IEC or Neutrik Powercon inlet for single phase models and a high current 3 phase / 5 wire Star configuration (184-264 VAC line to neutral) or 4 wire Delta configuration (184-
264 VAC line to line) connector for high power models. The amplifier systems are supplied with mating power cords. No wiring of power supply leads is required from the customer. Always ensure the supplied power supply lead is fully inserted and locked into place before the amplifier is powered On.

4 MAINTENANCE
4.1 General cleaning
For cleaning the front panel, use an anti-static foam cleaner and a soft lint-free cloth or tissue. Using abrasive materials or strong solvents may damage the surface finish or the front panel overlay.
4.2 RF connectors
If the RF connectors are used frequently, or left disconnected for long periods, there is a tendency for dirt and oxide deposits to build up. This increases the contact resistance and creates localized heating of the “RF out” connector pin, which may cause damage on high power models. Periodically inspect the inner pins of the RF connectors for damage or deposits, and carefully clean if required.
CAUTION: Do not use cleaning materials that leave a residue or that are abrasive for cleaning the
RF connectors, as this seriously degrades their performance.
When storing the amplifier for long periods, the RF connectors should be protected with the plastic covers provided.
4.3 Air-filter cleaning
CAUTION: Operating the amplifier with the air-filter clogged, may cause the amplifier to overheat.
The air-intake-filter on the amplifier front panel should periodically be checked for cleanliness. If it is seen to be obstructed with any dust or debris this should be cleaned away before the amplifier is operated.
4.4 Repairs
Repair work is to be carried out exclusively by an authorized AMETEK CTS repair department.
WARNING: Voltages of more than 230 VAC and are generated within the instrument. Do not open the cover.
Only original replacement parts and accessories are to be used.
Do not continue to use the instrument in the event of mechanical damage occurring. The metal chassis also performs insulating and protective functions.
4.5 Disposal
For the disposal of electronic devices, the country-specific regulations are to be considered. The equipment should be delivered to a specialized waste collection center.
Milmega and Teseq’ devices can be returned to AMETEK CTS in England or to their agency for adequate disposal. Alternatively, the equipment can be handed over to a specialized enterprise for disposal of electronic devices.
Details to used material and components.
The RF amplifier modules in this equipment contain Beryllium Oxide, and other components contain PTFE. The appropriate precautions and regulations must be observed concerning the disposal of this amplifier and certain internal components. Do not crush or incinerate.
Beryllium Oxide is a material used in the manufacture of RF devices. Toxic dust is given off when crushed.
PTFE is a material used in the manufacture of certain components within the amplifier. PTFE gives off toxic gasses when incinerated.
