Wiring the Ex d Models

To wire the Ex d flameproof sounder:
1.
Unscrew the M3 hex set screw on the side of the housing one full turn.
2. Remove the cover from the housing by turning the cover counter-
clockwise. Three 120-degree spaced reliefs are provided for a 3/8 inch
spanner wrench if needed. If the cover will not unscrew, back out the set
screw a few additional turns.
3. Loosen the captive Phillips screw retaining the driver/printed circuit
board (PCB).
4. Slide out the PCB until the terminals clear the housing. Strip the wire
insulation 6.5 mm (0.25 in). Maximum screw tightening torque is 0.5
N•m (4.5 in-lb).
5. Follow the instructions starting below for your line voltage and continue
to Step 6 on page 17. Refer to Figure 6 for the voltage selector
switch and page 17 for the tone chart.
