Safety requirements on the electrical installation
Electrical equipment (e.g. motors, contactors, cables, lines, relays)
must meet the following requirements:
Conformity with national regulations (e.g. NEC, VDE and IEC)
Suitability for the electrical conditions at the installation site
– Maximum operating voltage
– Maximum operating current
Suitability for the environmental conditions at the installation site
– Temperature resistance (minimum and maximum temperature)
– Stability against UV light when used outdoors
– Protection against water and dust (Nema or IP protection class).
Suitable fusing of the electrical circuit
– Overcurrent fuses (in accordance with the technical data of the
device input or output)
– Overvoltage class II surge limiters
Suitable disconnecting device (e. g. switch or circuit breaker) for the
mains supply of permanently mounted equipment with separate
mains connection
– in compliance with the following regulations
- IEC 60947-1
- IEC 60947-3
– in the vicinity of the equipment (recommendation)
Flame-resistant (cables and lines),
in compliance with the following regulations
– UL 2556 VW-1 (for USA, Canada)
– IEC 60332-1-2 (outside of USA, Canada)

Installation guidelines for lightning protection
When using the IQ S
ENSOR
N
ET
instrumentation, particularly in outdoor
areas, adequate protection against (electrical) surges must be
provided. A surge is a summation phenomenon of surge voltage and
surge current. It is generated through the indirect effect of a lightning
event or switching operation in the mains, in the grounding system and
in information technology lines.
To be adequately protected against the damaging effects of surges, an
integrated concept of the following protective measures is required:
internal device-related protective measures and
external protective measures of the installation environment.
