NOTICE

Risk of device damage by wrong voltage.

• Make sure that the voltage on the socket corresponds to the voltage given on the type plate

of the instrument.

• Always connect the device to an earthed socket. External connections and extension cables

must be provided with an earthed conductor lead (3-pole couplings, cable or plug equipment)

as the mains lead has a molded plug, thus avoiding risks due to inadvertent defective wiring.

• Make sure that no electric sparks form in the device or its surroundings as they might

damage the instrument.

On the K-376/K-377 sampler

• Connect the power cable to the power connection b

• Connect the cable to the K-375 device to the RS232 connector d
