1. Connect the shield of the RS-
485 cable to the ground lug.
2. Cord grip
3. RS-485 cable to Receiver
4. Power side
5. Intrinsically-safe side
6. NOTE: Attach one end of RS-
485 cable to RS-485 terminals
in the TLS RF and other end to
RS-485 terminals in the
Receiver. One twisted pair
connects to terminals - and +
(RS-485 signals) and the
second twisted pair connects
to terminals +15 and G
(Receiver power). You must
connect each wire of each pair
to the same terminals in the
Receiver (e.g., white w/blue
stripes to “-“ and white w/blue
stripes to “-“). (ref. Figure 24
on page 25). NOTE: see Figure
7 for wire connection tips.
NOTE: In sites with two daisy-
chained TLS RFs, the receiver
is only connected to the
master TLS RF.
