1.4 Safety notes
1.4.1 Electrical safety
While electrical safety in the handling of the 753 Suppressor Module is
assured in the context of the specifications IEC 1010-1 (protection class
I
, degree of protection IP20), the following points should be noted:
• Mains connection
Setting the mains voltage, checking the mains fuse and the mains
connection must be effected in accordance with the instructions in
section 2.2.
• Opening the 753 Suppressor Module
When the 753 Suppressor Module is connected to the power supply
the instrument must neither be opened nor should parts be removed
from it, otherwise there is a danger of coming into contact with com-
ponents which are live. Always disconnect the instrument from all
voltage sources before you open it and ensure that the mains cable
is disconnected from mains connection 19 19 !
• 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 753 Suppressor Module, 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.
1.4.2 General precautionary rules
• Handling of solvents
Check all pump tubings and all input and output lines periodically for
possible leaks. Follow the relevant instructions regarding the handling
of flammable and/or toxic solvents and their disposal.
• Regular exchange of pump tubings
Pump tubings are consumable material and must be replaced from
time to time (see Section 4.2.4). Suitable measures must be taken so
that any leak which might occur in the pump tubing or connections
during unattended operation will cause no damage (placing the
instrument at the bottom, collection device for any liquid which may
leak out).
