2. The second mounting option is DIN-rail mounting.
For both options see the diagram with ruler on the flip-out cover page.
2.3 Installation of cables and sensors
Tyco Thermal Controls insists on the use of a 30 mA residual current
device and a C-characteristic circuit breaker to provide maximum safety
and protection from fire.
2.3.1 Wiring diagrams
There are three wiring diagrams: C, D and E (see 5.5 Diagrams).
For connection of a single unit: Diagram
pag. 32
F1: Circuit breaker 20 A max. (C-Characteristic).
F2: Residual current device 30 mA.
For multiple unit connection on one phase system: Diagram
pag. 33
F1, F3, F5: Circuit breaker 20 A max. (C-Characteristic).
F2, F4, F6: Residual current device 30 mA
For multiple unit connection on a three phase system: Diagram
pag. 33
F1: Circuit breaker 3 x 20 A max. (C-Characteristic)
F2: Residual current device 3 x 30 mA
Double-pole electrical protection might be needed to comply with local
electrical standards.
