WARNING
Electric shock
Death or serious personal injury
- Before making any electrical connections, switch
off the power supply and make sure that it cannot
be accidentally switched on.
- All electrical connections must be carried out by a
qualified electrician in accordance with local
regulations.
- All electrical connections must be carried out in
accordance with the separate wiring diagrams
delivered with the system.
- The electrical connection of components must be
carried out in accordance with the separate
supplier manuals delivered with the system.
Make sure the voltage and frequency of the local
power supply corresponds to the technical
requirements of the system components. See section
.
Install separate fuses with sufficient capacity for all
system components.
This circuit is intrinsically safe. Use a separate cable
duct.
This circuit is intrinsically safe. Use a separate cable
