NOTICE
Incorrect power supply
Check before connecting that the existing supply voltage corresponds to that speci󹪝ed on the
label of the device.
Install the power line separately from the signal lines.
A power supply cable or an appliance plug is enclosed with the device, and must only be
connected by quali󹪝ed personnel (see Quali󹪝ed Personnel (Page10)). The cable is connected
to the appliance socket at the rear of the device. At the power supply end, the cable is
inserted into a mains socket.
19" rack unit
A 󹪞exible cable suitable for power supply cords must be connected to the appliance plug. The
cross-section of each conductor must be at least 1mm
2
(AWG 17). The cross-section of the PE
conductor must not be smaller than that of the L and N conductors. The cable must be suitable
for a temperature of at least 70 °C (158 °F) and must be approved for the country of use or the
location.
A readily accessible facility for mains disconnection must be provided in the immediate
vicinity of the analyzer.
Bench-top unit
A power supply cable must be used which is approved for the country of use or the location. The
minimum cross-section of each conductor must be at least 0.75mm
2
(AWG 18) as long as the
maximum length of the cable does not exceed 2m (61/2ft). Longer cables require larger
conductor cross-sections than 0.75mm
2
(AWG 18). The cable must at least be suitable for a
