Advice for Start-up
Do not apply voltage before regulator and heating are completely mounted!
A professional electrical connection is the precondition for safe operation of
the regulator. A certified electrician is required for electrical installation of
the temperature regulator and connection of the heating.
Please check following points carefully:
•
Compare mains voltage with data on the type plate
•
Ensure that the load circuit is switched-off while the configuration of the regula-
tor is changed. Unplug heating, if applicable. Reduce setpoint to prevent unin-
tended temperature rise.
•
The heating power of the connected heating, respectively the sum of the heating
power rates of all connected heatings must not exceed the maximum switching
power of the regulator (see type plate).
•
nOnly connect ohmic consumers to the regulator.
•
Permissible ambient temperature 0 ... 40 °C must be observed even in unfavor-
able circumstances. Avoid direct sunlight. Ensure sufficient ventilation.
•
The regulator should be installed protected from humidity and dirt. Do not install
the regulator near to inductive consumers/contactors.
•
Connect the regulator in a separate electric circuit. Do not directly connect any
further control circuits (e.g. contactors, ventilators) to the clamps.
•
nAlways superpose a master switch to the heating/regulator.
•
Protection category of the regulator (IP) only valid with plugged-in mating plug
and sealed cable screwings!
4 Mounting Advice
•
Only install the regulator on suitable heat-conducting mounting surface (e.g.
brickwork, metal console) with good contact to the bottom of the enclosure to
dissipate internal heat.
•
Recommended mounting position: vertical, if possible
•
Use boreholes in the housing for mounting.
