Installation Guide Wiring the TLS RF
12
LEGEND FOR NUMBERED BOXES
IN FIGURE 8
1. POWER WIRING NOTES:
- Barrier ground must be #12
AWG or larger diameter.
- Check to be sure that the
electrical resistance - between
the unit ground lug and a
known good earth ground is
less than 1 ohm.
- Connect the power supply
wires in the power panel to a
separate dedicated circuit.
- Electrical rating power input
- 120 Vac or 240 Vac, 50/60 Hz,
2 A max.
- See Figure 3 for actual
locations of power conduit
knockouts into the unit. Power
wiring must enter only in one
of these knockouts.
2. AC power input wires (#14
AWG) to AC input terminals.
3. Protective earthing conductor
(green and yellow). Attach
#12AWG barrier ground wire
to ground lug. Ground must be
the same as the supply and
less than 1.0 ohms to ground.
4. Attach chassis ground wire
(#14 AWG) to ground lug.
5. Connect the shield of the RS-
485 cable to the ground lug.
6. RS-485 cable from master TLS
RF.
7. See Figure 9 for connections.

the unused twisted pair back
to the cable’s jacket at each
end of the cable.
4. TLS RF Auxiliary
5. Connect the shield of the RS-
485 cable to the ground lug.
6. Connect like colored wires of
the twisted pair to like
