1 Introduction
1.4 Safety notes
While electrical safety in the handling of the 762 IC Interface 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
The mains connection 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 762 IC Interface 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 8 8 !
• 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 762 IC Interface, 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.
762 IC Interface8
2 Installation
2.1 Setting up the instrument
2.1.1 Packaging
The 762 IC Interface is supplied together with the separately packed
accessories in special packagings containing shock-absorbing foam
linings designed to provide excellent protection. The instrument itself is
packed in an evacuated polyethylene bag to prevent the ingress of
dust. Please store all these special packagings as only they assure
transport of the instrument free from damage.
2.1.2 Check
2.1 Setting up the instrument
After receipt, immediately check whether the shipment is complete and
has arrived without damage (compare with delivery note and list of
accessories in section 4.2). In the case of transport damage, see
instructions in section 4.4.1 "Warranty".
2.1.3 Location
Position the instrument in the laboratory at a location convenient for operation, free from vibrations and protected against a corrosive atmosphere and contamination by chemicals.
2.1.4 Arrangement of the instruments
The 762 IC Interface can be piled up together with other IC instruments
(e.g. 732, 733, 709).
762 IC Interface 9
2 Installation
2.2 Mains connection
2.2.1 Mains voltage and fuses
The 762 Interface has a power supply which automatically adjusts itself
to the existing mains voltage (100…240 V) and frequency (50…60 Hz).
It is equipped with an electronic overload protection device and also
has two fuses; however, these should only be exchanged by Metrohm
service technicians.
2.2.2 Mains cable
The instrument is supplied with one of three mains cables
• 6.2122.020 with plug SEV 12 (Switzerland, …)
• 6.2122.040 with plug CEE(7), VII (Germany, …)
• 6.2133.070 with plug NEMA 5-15 (USA, …)
which are three-cored and fitted with a plug with an earthing pin. If a
different plug has to be fitted, the yellow/green lead (IEC standard)
must be connected to the earthing socket 77 (protection class 1).
Any break in the earthing inside or outside the instrument can make it
a hazard!
Plug the mains cable into mains connection plug 88 at the 762 IC Inter-
face (see Fig. 3 and Fig. 5).
2.2.3 Switching the instrument on/off
The 762 IC Interface is switched on and off using mains switch 11 (see

4.4 Warranty and conformity
4.4.1 Warranty
The warranty on our products is limited to defects that are traceable to
material, construction or manufacturing error which occur within 12
months from the day of delivery. In this case, the defects will be rectified in our workshops free of charge. Transport costs are to be paid by
the customer.
For day and night operation, the warranty is limited to 6 months.
Glass breakage in the case of electrodes or other parts is not covered
by the warranty. Checks which are not a result of material or manufacturing faults are also charged during the warranty period. For parts of
outside manufacture insofar as these constitute an appreciable part of
our instrument, the warranty stipulations of the manufacturer in question
apply.
With the regard to the guarantee of accuracy, the technical specifications in the instruction manual are authoritative.
Concerning defects in material, construction or design as well as the
absence of guaranteed features, the orderer has no rights or claims except those mentioned above.
If damage of the packaging is evident on receipt of a consignment or if
the goods show signs of transport damage after unpacking, the carrier
must be informed immediately and a written damage report demanded.
lack of an official damage report releases Metrohm from any liability to
pay compensation.
If any instruments and parts have to be returned, the original packaging
should be used if at all possible. This applies above all to instruments,
electrodes, burette cylinders and PTFE pistons. Before embedment in
wood shavings or similar material, the parts must be packed in a dustproof package (for instruments, use of a plastic bag is imperative). If
open assemblies are enclosed in the scope of delivery that are sensitive to electromagnetic voltages (e.g. data interfaces etc.) these must
be returned in the associated original protective packaging (e.g. conductive protective bag). (Exception: assemblies with built-in voltage
source belong in a non-conductive protective packaging).
No warranty responsibility whatsoever will be accepted by Metrohm for
damage which arises as a result of non-compliance with these instructions.
