2.1 Unpacking and Installation
In order to ensure that your SM40 Centre functions properly, please follow these few simple instructions
after unpacking your unit.
1. Carefully check the enclosed system components for physical damage caused during shipping. Any
complaints should be made immediately to the shipping company.
2. Mount the Basic System frame in the appropriate position in the 19 inch rack unit (not higher than
shoulder height, so that the display and keyboard can be clearly seen).
3. Extension Frames are available to expand the Basic System into a larger system. These should now be
mounted, and wired according to the appropriate wiring diagrams.
4. Mount the amplifiers and auxiliary equipment in the rack(s). If power amplifiers are mounted beneath
SM40 frames, a heat shield should be installed above them to deflect hot air currents.
5. Taking care to avoid earth (ground) loops, wire the mains power to the units.
SM40 will operate successfully on mains voltages from 187 V to 264 V when tapped for 220 V, and
from 90 to 132 V when tapped for 110 V. Be sure to check that your system is wired for the correct
mains voltage. Refer to Chapter 2.2 Power Supply Modules.
Warning: Because it is possible to touch the mains voltage terminals when the frame back panels are
opened, it is advisable not to turn the power on at this stage.
6. Open the back panel of the Basic system, and check that all of the connectors on the Interconnection
Board and Termination boards are firmly in place. If, in the unlikely event that one of the connectors
has become disconnected, refer to the enclosed basic system wiring diagram.
7. Referring to Termination Board illustrations in Chapter 5.2, wire the Call Stations, auxiliary input
sources, amplifiers, etc., to the screwblock connectors.
8. Plug the screwblock connectors into the termination boards, ensuring that they are in the correct
locations.
9. Open the front panel of the rack frame and gently push each of the circuit cards to make sure that
they are all firmly connected to the Interconnection Board.
10. If, after double checking that all of the mains power and signal wiring is correct, and that the system is
adequately earthed, switch on the mains power to the rack.
11. The display on the front panel shows:
For installer programming refer to Chapter 4.3.4.
