Connection to the mains and PE
The instrument conforms to protection class 1. Operation without a protective earth connection is forbidden!
Before switching on the device, check whether the selected voltage matches the supply voltage. The posi-
tion of the voltage selector must correspond with the mains. If you change the mains voltage, replace the
fuses according the recommended value.
A proper protective earth connection through the connector of the power cord is essential for safe operation.
High leakage currents can cause the residual current circuit breaker of the mains to trip. In this case, the
use of an isolating transformer is required.
Handle the power cord carefully. Hold the plug when unplugging the cord.
Never use the product if the power cord or the plug is damaged.
Use only power cords and connector specified for your product.
Do not abuse the cord. Never use the cord for carrying, pulling or unplugging the unit. Keep cord away from
heat, oil, sharp edges or moving parts.
Prevent the device from being switched on or energized unintentionally. Make sure that the switch is in the
off position before connecting the device to the mains.
Disconnect the power plug if you are not going to use the device for a long period of time.
1.4
Connections to other ports with dangerous voltages (AE, EUT, RF port ...)
Only use the connection cables and plugs specified for your product which enable safe working. They must
comply with the required classification and have suitable voltage and current ratings for the application.
Handle the connection cable carefully. Hold the plug when unplugging the cable.
Never use the product if the connection cable or plug is damaged.
Avoid touching conductive parts unless they have been de-energized by suitable means and secured
against being switched on again for the period of handling. Industrial connectors often have insufficient pro-
tection against electric shock due to their application.
1.5
Connection to the ground plane or Faraday cage
Remove the protective foil from under the device and adapter housing to ensure good electrical contact.
Light equipment should be weighted down, clamped to the base plate or other measures should be taken to
ensure good electrical contact over a wide surface area and on a permanent basis.
Connect the device with the ground plane before using.
The operation without a second, only with a tool removable earth leakage connection is
prohibited.
Check the ground connection at regular intervals.
Ensure that a reliable return path for the interference current is provided between the equipment under test
(EUT) and the generator. The reference ground plane and the earth connections to the instrument as de-
scribed in the relevant test standard serve this purpose well.
1.6
Disconnection from the mains, PE, ground and control devices
Always set the power switch to the "Off" position and wait few seconds before disconnecting the power cord.
Disconnect the power cord and all connection cords when moving the unit.
1.7
Use proper fuses
To avoid fire hazard, use only fuses as specified in the parts listing for your product - matching type, voltage
and current rating.
1.8
Risk of electric shock
These operating instructions form an essential part of the equipment and must be available to the operator at all times. The
user must obey all safety instructions and warnings.
