Electrical installation
The SIG350 is used in electrical installations. When working on the module or the plant,
the safety rules of electrical engineering must be observed.
The following information must be observed, depending on the connection type:
•
Switch off the power supply to the device before starting work on it.
•
The connection of the network and IO-Link cable of the SIG350 must be voltage-
free (U
B
= 0 V). Only apply voltage/switch on the voltage supply (U
B
> 0 V) once all
electrical connections have been established.
•
All unused male and female connectors must be sealed with sealing caps to
ensure enclosure rating IP 67.
•
If possible, each of the sensor/bus and actuator power supplies should be drawn
from different sources. The total current of the module must not exceed 16 A.
•
In case of separate actuator and sensor supply, always switch on the sensor
voltage first and then the actuator voltage to ensure error-free function of the
digital inputs and outputs.
•
An incorrect supply voltage may result in damage to the device.
•
Cables and/or modules damaged by short-circuits can overheat and cause fires.
Provide sensible current monitoring or fuse. The fuse protection must be designed
for max. 16 A.
•
During operation of the module, the device surface may heat up. If necessary,
wear suitable thermal gloves.
•
Only install cables and accessories that comply with the requirements and regu‐
lations for safety, electromagnetic compatibility and, if applicable, telecommunica‐
tions terminal equipment and the specification requirements.
•
Observe the derating when using the product. The ambient temperature and the
current have an influence on the heating of the product (
)
NOTE
Only operate the product with DC 24 V PELV (Protective Extra-Low Voltage) or SELV
(Safety Extra-Low Voltage) voltage sources.
There is a risk of electric shock if this is not observed.
Only use a power supply unit that allows max. 60 V DC or 25 V AC in the event of a
fault.
