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 electri-
cian.
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.

Connection via direct wiring
Connection/adjustment to the power supply not carried out by an electrician
MORTAL DANGER FROM ELECTRIC SHOCK
Have the connection/adjustment to the power supply carried out by an electrician.

2.11.3
Converting the power supply connection
To restore the factory settings, the connection values must be
re-entered
.
The following temperature control units can be retrofitted:
Unistat TR401, TR401w HT, TR402, T305, T305 HT, T305w HT
▪
The temperature control units can be set to either 230 V/50 Hz or to 400 V/50 Hz.
▪
Install the temperature control unit at the location provided.
▪
The maximum current consumption at 230 V operation is just below 16 A.
However, there are 230 V power supplies with a smaller fuse protection. During initial startup you
will be prompted to adjust the power consumption of the temperature control unit to your cur-
rent power supply.
The choices are: 10 A or 16 A
Switching the supply voltage varies the heating capacity (see data sheet from page 89 in the sec-
tion
. It does not affect the control mode.
You can also change the maximum power consumption at the Pilot ONE later on.
