3.2 Protection
Fuses for the equipment should be provided by the customer. The
protective organs upstream must be adapted to suit the maximum
possible current provided by the controller (refer to the technical data).
The inside of the controller is equipped with 2 miniature fuses (ø 5*20 mm)
in the connection area:
F1 (on the left): primary 230V/500mA delay fuse for electronic
components.
F2 (on the right): secondary 315mA delay fuse for electronic components.
3.1 Laying the Cables
General Information
G
Install all low voltage lines (room temperature sensors, digital inputs)
taking the shortest route.
G
It must be guaranteed that the extra low-voltage cables and the
high-voltage cables are physically separated, e.g., using metallic divider
plates on cable ducts.
Maximum permissible cable lengths:
Mains
Depending on the load and cable
cross-section
Air heaters (all!)
max. 250 m
Room temperature sensors
max. 100 m
External change-over contacts
