17、 . . KI-1390 INSTALLATION Refer as necessary to IL0157 (page 3) for the following steps. Step 1. If necessary, rough the masonry box into the wall. Step 2. Consult the appropriate manuals from the above list and pull through the wiring from the power supply or the clock system and any switches that

18、are to be used with the unit. Do not apply power to these lines until it is time to test the installation. Step 3. Orient the mounting brackets as shown in ILO157. Place a “u” nut over the small center tab on the front of each bracket; the flat side of the nut should face the front. Step 4. Place th

19、e clock module and its attached trans- former on a suitable work surface. Orient a “U” nut so that its flat side faces the same way as the mounting base of the transformer, then push the “LJ” nut onto one of the narrow ends of the base. In like manner, install a second “U” nut on the opposite end of

20、 the base. Step 5. Orient the transformer so that the side with the wires attached to the clock module faces you and its mounting base faces to the left. Step 6. Place the transformer inside the left mounting bracket, align its “U” nuts with the holes in the brackets large flange, and secure the tra

21、nsformer to the bracket with two #6 x 4;” screws Step 7. Orient the clock module so that its LED display faces you and the electrical connections between the display and the circuit board are at the bottom. Use four #6 x Y? screws to secure the clock module to the threaded standof make sure that the

22、re is enough space between the back of the assembly and the box for you to work on the wiring and stuff it back inside the box. Step 9. Using the large wire nuts, attach the power- supply wires to the appropriate transformer wires of the clock: 24 VAC120 VAC BrownBlTXVn BlackBh? Note: For hospital i

23、nstallations, Rauland recommends the use of a customer-supplied isolating 24-VAC power supply that can furnish 300 mA to each clock. Step 10. Cover the end of the unused transformer wire with the small wire nut. CAUTION Never connect the black transformer wire to a 120-VAC power suppk, such a COMeCt

24、iOn will damage the module. Refer to the applicable power+wpply installation manual for additional information and instructions. 1 Step 11. If there are switches, connect their wires to the clock module now. Step 12. Carefully push the wires inside the masonry box and secure the brackets to the box

25、with the four #6 x SW screws. Step 13. Before installing the dress panel, you may wish to test the clock by powering it up and running the operations listed in the applicable manuals. However, if this is part of a partially completed system, you may prefer installing the panel first, to prevent dama

26、ge to, or loss of, these parts. Step 14. Place a stainless-steel washer on each of the two #6 x K” black screws, then place these parts within easy reach. Align the screw holes of the dress pane1 with the “u” nuts previously installed on the mounting brack- ets. Secure the panel to the brackets with the screws.
