1. Internal Earth Terminal 2 off M20 Cable Entri y able Entries Figure 3 When using the external earth terminal a cable crimp lug must be used The cable lug should be located between the two M5 stainless steel flat washers The M5 stainless steel spring washer must be fixed between the outer flat washer and the M5 stainless steel nut to ensure that the cable lug is secured against loosening and twisting The internal earth bonding wire ensures that a good quality earth is maintained between the sounder section casting and the beacon section casting 10 Cable Glands The BExDCS110 L1D unit has dual cable gland entries which have an M20 x 1 5 entry thread as standard Only cable glands approved for Ex d applications can be used which must be suitable for the type of cable being used and also meet the requirements of the Ex d flameproof installation standard EN60079 14 2008 IEC60079 14 SAFETY WARNING If the unit is used at high ambient temperatures i e over 40 C then the cable entry temperature may exceed 70 C and therefore suitable heat resisting cable glands must be used with a rated service temperature of at least 110 C When only one cable entry is used the other one must be closed with an Ex d flameproof blanking plug which must be suitably approved for the installation requirements For combustible dust applications the cable entry device and blanking elements shall be in type of ex2. 50 C to 70 C 5 Location and Mounting The location of the unit should be made with due regard to the area over which both the sounder and beacon warning signal must be audible and visible The unit should only be fixed to services that can carry the weight of the unit The unit should be securely bolted to a suitable surface using the 7mm diameter boltholes in the stainless steel U shaped mounting bracket see figure 1 The angle can then be adjusted in the direction such that its warning signals can be both heard and seen This can be achieved by loosening the two large bracket screws in the side of the unit which allow adjustment in steps of 18 On completion of the installation the two large bracket adjustment screws on the side of the unit must be fully tightened to ensure that the unit cannot move in service Plastic Acoustic Horn Sounder Beacon Anti static Plastic Section Section SS Flashdome Guard Bracket 6 Access to the Flameproof Enclosure In order to connect the electrical supply cables to the unit it is necessary to remove the beacon section to gain access to the flameproof chamber To achieve this remove the four M6 hexagon socket head screws see figure 2 and withdraw the beacon section taking extreme care not to damage the flameproof joints in the process Note the four M6 screws are Class A4 80 stainless
