Section 7 of this manual 2 S S Mounting 7 Safety Warning Electrostatic Hazard The acoustic horn section is made of ABS Plastic therefore to avoid a possible ELECTROSTACTIC CHARGE the unit must only be cleaned with a damp cloth 8 Access to the Flameproof Enclosure In order to connect the electrical supply cable and the telephone line cable to the Sontel it is necessary to remove the flameproof cover to gain access to the flameproof chamber To achieve this remove the four M6 hexagon socket head screws see figure 2 and withdraw the flameproof cover taking extreme care not to damage the flameproof joints in the process Note the four M6 screws are Class A4 80 stainless steel and only screws of this category can be used on these Sontels It is therefore important that these screws and their spring washers are kept in a safe place during installation 4 off M6 Cover Screws External Earth Terminal On completion of the cable wiring installation the flameproof joints should be inspected to ensure that they are clean and that they have not been damaged during installation Also check that the earth bonding wire between the two casting sections is secure and the O ring seal is in place When replacing the flameproof cover casting ensure that it is square with the flameproof chamber casting before inserting Carefully push the cover in place al
