Recommended Installation Procedure
!
!
Please read and observe the instructions and guidelines in Section “ 4 Safety and Precautions ” (page 11 )
prior to installation. Failure to follow these instructions and guidelines may cause damage to the
equipment.
1. Ensure that the power supply to the DANS01 is disconnected at the central equipment rack.
2. Remove DANS01 front panel by unscrewing the four corner fixings (4 x Philips screws).
3. Two plastic coated steel tethers are provided to hold the front panel when the DANS01 is opened, and
to provide strain relief to the wiring connecting the PCB to the terminal block on the back box. This
allows the front panel to be opened for maintenance purposes without disconnecting the wiring. The
tethers are connected to the back box by the screws used to secure the terminal plate to the back
box. These screws should be the bottom two fixings; see
Figure 1 .
4. If it is desired to install the back box with the electronics assembly temporally removed for
safekeeping, first disconnect the plug-in connector from the PCB, and also disconnect both of the
tethers securing the front panel to the back box; see
Figure 1 .
In order to disconnect the tethers unscrew the appropriate screws. Re-fit these screws after
disconnecting the tethers.
