1 Introduction 1.3 Information on the Instructions for Use Please read through these Instructions for Use carefully before you put the 771 IC Compact Interface into operation. The Instructions for Use contain information and warnings to which the user must pay attention in order to assure safe operation of the instrument. 1.3.1 Organization These 8.771.
1.3 Information on the Instructions for Use 1.3.2 Notation and pictograms The following notations and pictograms (symbols) are used in these Instructions for Use: Range Menu item, parameter or entry value in «IC Net» program SYSTEM STATE Program window in «IC Net» program Button in «IC Net» program [ RUN/STOP ] 5 Switch or key Part or control of 771 Hazard This symbol draws attention to a possible danger to life or of injury if the associated directions are not followed correctly.
1 Introduction 1.4 Safety notes While electrical safety in the handling of the 771 IC Compact 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.
2.1 Setting up the instrument 2 Installation 2.1 Setting up the instrument 2.1.1 Packaging The 771 IC Compact 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 Installation 2.2 Mains connection 2.2.1 Mains voltage and fuses The 771 IC Compact 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.
2.3 Connection to the PC 2.3 Connection to the PC 2.3.1 Connecting cable Always switch off 771 IC Compact Interface and PC before you connect the two instruments with the 6.2134.100 Cable. Connect the PC connection 4 at the 771 IC Compact Interface to one of the serial COM ports at the PC using the 6.2134.100 Cable (9 pin/9 pin). If only a 25-pin COM interface is available on the PC then the 6.2125.110 Adapter cable or a commercially available adapter must be used. 6.2134.100 771 Fig.
2 Installation 2.4 Connection of detectors 2.4.1 General information Before an external instrument is connected to the 771 IC Compact Interface, the 771 IC Compact Interface must always be switched off using mains switch 2 ! The 771 IC Compact Interface has two connections 5 and 6 for analog input signals (see Fig. 2). Information about the technical data of these interfaces is given in section 4.1.
