WARNING
The hazardous area must be de-classified prior to
removing a junction box cover with power applied.
1. Remove the cover from the junction box.
2. Connect external system wiring to the appropriate
terminals on the terminal block inside the junction
box. See Figure VII-17 for terminal block location
and Figure VII-18 for terminal identification. The
input to the IDC consists of one or more normally
open switches (momentary pushbuttons are not
recommended), with a 10K ohm, 1/4 watt EOL
resistor in parallel across the last switch. An EOL
resistor must be installed on both IDC inputs
(including unused inputs). Wiring impedance must
not exceed 500 ohms.
3. Check the wiring to ensure proper connections.
4. Set the node address for the device. Refer to
“Device Address Switch Setting” in the “Switch
Setting” section (Section VIII) of this manual for
complete information regarding the switch setting
procedure.
5. Install the communication module inside the
junction box. Be sure that the keyed ribbon cable is
properly connected.
6. Inspect the junction box O-ring to be sure that it is
in good condition and properly installed. Lubricate
the O-ring and the threads of the junction box cover
with a thin coat of an appropriate grease to ease
installation and ensure a watertight enclosure. The
recommended lubricant is a silicone free grease,
available from Det-Tronics. Place the cover on the
junction box. Tighten only until snug. Do not over
tighten.
