2.8.2.1 Immersion depth of the probe [67]
Make sure that the
>Probe<
[67] is immersed into the thermofluid to be cooled at least up to the
upper end of the cooling coil.
Otherwise, ice crystals will form on the
>Probe< [67], resulting in an inferior transmission of energy.
Model F (with flexible >Probe< [67]):
Never reduce a bending radius of 40 mm when bending the flexible
>Probe<
[67].
2.8.3 Connecting the functional earth
PROCEDURE

If required, connect the temperature control unit’s >Functional ground terminal< [87] to the
building’s grounding point. Use a ground strap for this purpose. For the exact position and thread
size please refer to the wiring diagram. → From page 46, section »Annex« .
2.9 Connecting to the power supply
Based on local circumstances, it may be that you need to use an alternative power cable instead of
the supplied original power cable. Do not use a power cable that is longer than 3 m to be able to
disconnect the temperature control unit at any time from the mains. Have the mains cable only
replaced by a qualified electrician.
2.9.1 Connection using socket with protective earth (PE)
Connecting to a power socket without protective earth (PE)
MORTAL DANGER FROM ELECTRIC SHOCK

Always connect the temperature control unit to safety sockets (PE).
Damaged power cable/power cable connection
MORTAL DANGER FROM ELECTRIC SHOCK

Do not start up the temperature control unit.

Isolate the temperature control unit from the power supply.

Have the power supply cable/power supply connection replaced and inspected by an electrician.

Do not use a power cable that is longer than
3 m
.
Incorrect power supply connection
DAMAGE TO THE TEMPERATURE CONTROL UNIT

Your building's existing power supply voltage and frequency must match the data provided on
the rating plate of the temperature control unit.
In case of uncertainties about an existing protective earth (PE), have the connection inspected by
an electrician.
