6. Commissioning, operation
Voltages greater than AC 50 V or DC 120 V:
■
- Do not connect circuits simultaneously with extra-low voltage circuits or with
safety extra-low voltage (SELV) or protected extra-low voltage (PELV).
- Circuits must offer a device, external to the measuring instrument, that
enables the instrument to be isolated from the electrical supply. This must be
easily accessible and be marked as the isolation device for the instrument.
- Cables for the circuit must fulfil the isolation requirements and conform to, for
example, IEC 60227 or IEC 60245.
With flexible connecting cables, use isolated end splices.
■
Connecting cables must be suited to the ambient temperature range of the
■
application.
Seal the cable entry with the appropriate approved cable glands.
