1.5 Safety notes
1.5.1 Electrical safety
While electrical safety in the handling of the 763 PVC Thermomat is as-
sured in the context of the specifications IEC 1010-1 (protection class 1,
degree of protection IP20), the following points should be noted:
• Mains connection
Setting of the mains voltage, checking the mains fuse and the
mains connection must be effected in accordance with the instruc-
tions in section 2.3.
• Opening the 763 PVC Thermomat
If the 763 PVC Thermomat 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 components
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 13 13 !
• 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 763 PVC Thermomat, 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.
1.5.2 General precautionary rules
• Take care with hot reaction vessels
Avoid any contact with hot reaction vessels. Place them in the sup-
plied vessel holder to cool them down.
