Wiring the Ex de Models
CIRCUIT BOARD DAMAGE: The DC sounders are polarity sensitive,
and MAY BE DAMAGED by incorrect electrical hookup. When
connecting the DC sounder to the voltage supply lines, POLARITY
MUST BE OBSERVED. In addition, damage will result if the voltage
rating of the particular model is exceeded by more than 10 percent.
To wire the Ex de models:
1.
Unscrew the four M4 socket-head cap screws and remove the terminal
box cover.
2.
Strip the wire insulation 8 mm to 9 mm (0.33 in).
NOTE: When using more than one single or multiple strand lead, the
connection into either side of any terminal must be joined in a suitable
manner, e.g. two conductors into a single insulated crimped bootlace
ferrule.
3.
To connect wires, press the pushbutton on the terminal block with a
Phillips screwdriver and insert the wire into the round opening. Release
pushbutton to make connection.
4.
Follow the instructions starting below for your line voltage and continue
to Step 5 on page 22. Refer to Figure 6 on page 13 for the voltage
selector switch and page 17 for the tone chart.
