8.4 Wiring the device
Danger
risk of injury due to electrical voltage.
▶
Shut down the electrical power source of all the conductors and
isolate it before carrying out work on the system.
▶
If a 12...36 V DC powered version is installed either in a wet
environment or outdoors, all the electrical voltages must be of
max. 35 V DC.
▶
All equipment connected to the device shall be double insu-
lated with respect to the mains according to the standard
IEC 61010-1:2010.
▶
Observe all applicable accident protection and safety regula-
tions for electrical equipment.
• Use a filtered and regulated 12...36 V DC power supply.
• Make sure the installation is equipotential (see chap. 8.4.2).
• Use shielded cables with a temperature limit of 80 °C
minimum.
• Do not install the connection cables near high voltage or
high frequency cables; If this cannot be avoided, observe
a min. distance of 30 cm.
• Protect the power supply of the device with a 100 mA
time-delay fuse and a switch.
• Protect the power supply of each transistor output with a
750 mA fuse.
