All frost protection thermostats require a 24 VAC/DC power supply. The electrical wiring
must be realized via the integrated Ex-e terminal box acc. to ATEX. The terminals’ type of
protection is “Increased safety Ex-e”.
Attention: Before opening the terminal box cover, the supply voltage must be shut off !
The supply has to be connected at terminals 1 (
−
/~) and 2 (+/~).
At different relay and supply voltages (24 VAC/DC)
the cable installation must be considered
(see “Information for Installation”) !

A. Installation, commissioning, maintenance
All national and international standards, rules and regulations must be complied with.
Certified apparatus must be installed in accordance with manufacturer instructions.
If the equipment is used in a manner not specified by the manufacturer, the safety protec-
tion provided by the equipment may be impaired. For electrical installations design,
selection and erection, EN/IEC 60079-14 can be used.
Attention: Apply all Ex rules and regulation before opening the internal terminal
box. Do not open cover when circuits are live!
Draw the wiring cables through the cable glands. For connection use the internal Ex-e
approved terminal box and connect equipotential bonding.
After connection install the cables in a fixed position and protect them against mechanical
and thermical damage. Close all openings and ensure IP protection (min. IP66).
Avoid temperature transfer and ensure not to exceed max. ambient temperature! For
outdoor installation a protective shield against sun, rain and snow should be applied.
Sensors are maintenance free. An annual inspection is recommended. For electrical
installations inspection and maintenance, EN/IEC 60079-17 can be used.
Clean with damp cloth only.
Ex sensors must not be opened and repaired by the end user.
B. Long cabling
We recommend using shielded signal wires and to connect one end of the shield to the
...Bin-... terminal box.
C. Separate ground wires
For supply and signal wires use separate grounds.
D. Relay output
Wires for safety extra-low voltage must be installed separately from other circuits. At
24 VAC/DC only supply and signal wires are permitted in one cable, in all other cases
use separate or double isolated cables. An over-current protection fuse < 10 A has to
be provided by the installer.
