4.2 Electrical mounting
Voltage supply
→ For auxiliary power, see product label
→ For further details on electrical mounting, see IN 00.50
This equipment is intended for operation with low voltages, which are separated from the AC 230 V (50 Hz) mains
voltage – or voltages greater than AC 50 V or DC 120 V for dry environments. A connection to an SELV circuit is
recommended, or alternatively to circuits with a different protective measure in accordance with IEC 60364-4-41
installation standard. The connection can also be made in line with "Class 2 Circuits" or "Class 2 Power Units" in
accordance with CEC (Canadian Electrical Code) or NEC (National Electrical Code).
For instruments with North American certification per UL/CSA IEC 61010-1:
The supply for the instrument must be made via a limited-energy circuit in accordance with section 9.4 of
UL/EN/IEC 61010-1 or LPS in accordance with UL/EN/IEC 60950-1/CSA C22.2 No.60950-1 or Class 2 in accordance
with UL1310/UL1585 (NEC or CEC). The voltage supply must be suitable for operation above 2,000 m should the
instrument be used at this altitude.
Shielding and grounding
The instrument must be grounded via the cable shield.
