1. Figure 2 Components of the Dolomite Enclosure without batteries Page 7 ROCK DOLOMITE CENTRAL RECORDING SYSTEM SUPPLEMENTAL MANUAL DOCUMENT 300718 Revision NC Installation Considerations i e before installation The Dolomite enclosure is designed to mount on a wall using direct bolts into concrete or using mounting supports The system is heavy so it is essential that it is bolted to a wall that can bear the weight of the enclosures and the batteries Add sufficient room around the enclosure for conduit entry and door opening Size The overall dimensions are Width 22 5 57 cm Depth 16 41 cm Height 26 66 cm Weight 45 kg 100 Ibs without batteries 68 kg 150 Ibs with 2 batteries 90 kg 198 Ibs with 4 batteries You will need to provide four mounting anchors as described below or purchase a uni strut mounting kit from Kinemetrics to mount the enclosure P N 503244 PL Accessory Power Box You will also need to plan for the installation of the AC supply telephone line and GPS antenna cable in the correct position for connection to the enclosure The individual sensors also have to be placed and cables run from them to enter the enclosure Entrance to the enclosure is through one or more of the four conduit holes at the top rear of the enclosure Equipment Required for Installation In addition to the equipment recommended in the Digitizer manual you will also need the following additional items e Tools2. It is suggested that you remove the Digitizer to reduce the weight of the enclosure during mounting and make it easier to bring the cables into the enclosure Caution The Digitizer and its expansion housing can weigh up to 26 Ib 11 8kg The Digitizer housing has a 304024 Granite Support bracket attached to its top and bottom back edges These remain attached to the Digitizer To remove the Digitizer unscrew the three bracket screws between the bottom bracket and the base plate As you support the Digitizer to be sure that it remains on the guide pins release the three top screw from the base plates Lift the Digitizer off of the guide pins and out of the enclosure Set it aside safely until enclosure installation is complete Mount other Communication Equipment to Enclosure If other equipment such as external communication options are to be added to the enclosure they should be firmly secured so they cannot move during an earthquake Additional straps can be made and bolted to the enclosure or door to secure this equipment Initial AC Power Test Warning AC power must be off at the source before beginning the installation Fuses should be removed so power cannot be re applied until the installation is complete A qualified electrician should perform this installation AII local electrical codes should be obeyed The enclosure AC power cord should be disconnected from the source until all electrical work is completed and inspected The
