1.4 Safety notes
While electrical safety in the handling of the 782 IC Column Thermostat
is assured in the context of the specifications IEC 1010-1 (protection
class 1, degree of protection IP40), the following points should be
noted:
• Mains connection
Setting the mains voltage must be effected in accordance with the
instructions in section 2.2.
• Opening the instrument
Inside the instrument there are no parts which must be set or adjusted
by the user.
If the 782 IC Column Thermostat is connected to the power supply,
the instrument must not be opened nor must parts be removed from
it, otherwise there is a danger of coming into contact with compo-
nents which are live. Hence, always disconnect the instrument from all
voltage sources before you open it and ensure that the mains cable
is disconnected from mains connection 12 12 !
• Protection against static charges
Electronic components are sensitive to static charging and can be
destroyed by discharges. Before you touch any of the components
inside the 782 IC Column Thermostat, you should earth yourself and
any tools you are using by touching an earthed object (e.g. housing of
the instrument or a radiator) to eliminate any static charges which
exist.
