5.0 Installation

CAUTION: Before connecting any components, see Before You Begin on page 13.

Star / Delta Configuration

If supplied with 3 phase mains in Star (Y) connection, a neutral line must be supplied.

In Delta configuration no neutral is required.

Mains Input

 Mains input is via a ready wired IEC 60309 3 phase plug.

 Star (Y) configuration is supplied with a 5-pin plug. Delta configuration is also supplied with a 5-pin plug; although neutral is present, it is unused.

 If the plug requires rewiring, the brown, black, and grey lines are live 1, 2, and 3 respectively, blue is neutral (Star (Y) only), and green/yellow is earth.

 Access for mains disconnection must be maintained at all times.

Amplifier Protection

The amplifier is protected by means of a miniature circuit breaker (MCB) which is located at the rear of the power supply unit. Where possible it is best to position the amplifier so that the MCB is accessible. www.ets-lindgren.com Installation 15

6.0 Operation

CAUTION: Before placing into operation, see Before You Begin on page 13.

Note: Make sure you are satisfied with the contents and condition of your system prior to placing it into operation.

Warning: Avoid exceeding the stated maximum input level as this can cause a risk of damaging the equipment.

Warning: There is a significant risk of an electrical or burn hazard; to avoid this, always ensure the output is terminated into a suitable load prior to switching on the equipment.

Equipment Use

 The equipment must only be used for its intended purpose.

 All parts of the equipment must remain connected to ensure that protective circuits operate. Disconnecting parts of the equipment may impair operation and safety.

Mains Switch

The amplifier is switched on or off by pressing the green/red button on the front of the power supply unit.

Standby/Operate Switch (Centre Unit)

Pressing the standby/operate switch toggles the state of the amplifier between

Standby and Operate modes. The blue halo indicator flashes in Standby mode, whereas steady blue indicates Operate mode. www.ets-lindgren.com Operation 17

Fault Indicator (Red LED)

Should a fault be detected, the red LED on the centre unit front panel will be illuminated. The amplifier will be forced into standby mode and the unit will cease to function (only the fans will continue to operate). This action is latching, therefore only when the fault has been cleared can the amplifier be reset; this is done by pressing the standby/operate switch.

The reasons for the system fault light to illuminate are as follows:

 Excess module temperature

 Air cooling failure (fans failing to operate)

 Power supply failure

Interlock Indicator (Orange LED)

When the rear panel interlock is activated the interlock indicator will illuminate and the amplifier gain stages will all be turned off. This action is latching; therefore, the amplifier will return to Standby mode when the interlock is released.

Local Lockout Indicator

This indicator is used when the USB/GPIB Interface option is fitted. Refer to the separate Remote Control Interface manual supplied.

RF Input (Depending on model)

The RF input will accept a signal from an RF generator. This input must be within the operating frequency range of the 8000-003 amplifier system. An amplitude of up to

0dBm will be sufficient to saturate the amplifier. Operation outside the specified frequency range should not be attempted as it may subject the amplifier to undue internal stress.

RF Output (Depending on model)

WARNING: The centre conductor of the RF output represents a severe burn hazard to personnel.

Never operate the amplifier without a proper termination or with defective cables or connectors.

18

This connector must be suitably terminated at all times during operation. Ensure that the cable is capable of handling the power available, which may be as much as

900 watts.

Operation www.ets-lindgren.com

Air Inlet

This amplifier requires a free air supply for cooling; the front air inlet must not be restricted.

Safety Interlock

 A dual interlock system can be operated by applying either short circuit (S/C) or open circuit (O/C) to mute the amplifier.

In order for the amplifier to operate, the Interlock BNC connector must be S/C and the Interlock must be O/C. If the Interlock is O/C or the Interlock is S/C the amplifier will be muted.

 The amplifier is delivered without the interlock applied and will be ready to operate.

 The interlock function is latching so when the interlock is removed the amplifier will be in standby mode. Press the standby/operate switch to return to normal operation.

 Current drawn from the interlock BNC connectors under short circuit conditions will typically be 2.8mA.

Fan Outlet

This amplifier requires a free air supply for cooling; the rear air outlets must not be restricted. www.ets-lindgren.com Operation 19
