External Connections
Punch a hole at the relevant location and of the appropriate size in one of the perforated
circles at the bottom of the RTU housing and thread the wires through the opening.
Telephone Line Option (See Figure 4-6)
There are two options for connecting the line wire to the Line Interface Unit:
– If the telephone line has an RJ11 connector plug it into the LINE connector on the unit's
front panel.
Or:
– If the telephone line is comprised of two wires connect the wires to terminals #1 and #2
of the unit's front panel TB. The polarity is insignificant.
