The weatherproof enclosure should be surface mounted using appropriate fixings and sealing
washers.
1.
Using the 6x outer screws, remove the clear Perspex lid.
2.
Using the 4x black dome nuts, remove the text legend fascia plate bezel.
3.
Remove the internal printed circuit board using the 2x screws located in the centre of the PCB.
4.
Drill 4 x 4mm fixing holes in the rear of the back box near each corner and fix the back box to
the wall using appropriate fixing screws or bolts. Ensure that a watertight seal is maintained
around the fixing holes.
5.
Re-instate the printed circuit board and fit the acrylic text legend to the fascia plate bezel using
the 6x M4 nuts provided.
6.
It is recommended that the fascia plate bezel complete with acrylic text legend should be re-
instated following initial testing of the system.
Cabling
The maximum size of cable that the terminals will accommodate is 2.5mm². The interconnecting
external cables should be connected to the back box using suitable cable glands. On the 4210-0120
back box, waterproof lock-tight glands should be used to ensure a weatherproof seal is maintained.
Ensure that cable tails of sufficient length are maintained to reach the terminals without cutting across
the front surface of the internal printed circuit board as this will impair the illumination of the sign.
The Warning Sign can be configured to illuminate in two ways. For voltage reversal, 2 wire
applications and for use with the Ampac Agent Release module, refer figure 1. For common positive,
switched negative 3 wire applications, refer figure 2.
Setting the Configuration Switches
The Warning Sign can be configured to operate in a variety of ways using SW2 8 way DIL switches
located on the printed circuit board.
Operational LED Colour Selection SW1 - Red or Yellow and should be set to suit the application of the
Warning Sign.
Operational Functionality SW2 - Table 1 outlines the functionality of the on-board switches located at
SW2, switches 1 - 8.
