2.2 POWER WIRING
All wiring should be installed according to local and/or national codes. Refer to Figure 2
for the connection of the power wiring. The AC input power connects to the 2 pole termi-
nal block. The neutral wire should be connected to the terminal on the right and the
“LINE” conductor connected to the terminal on the left. The terminal on the left wires
through the fuse to the transformer.
A green ground screw is provided in the SmartBob TS1 for electrically grounding the unit.
A good Electrical ground must be connected to the TS1 for safety and to bleed off any
static electrical charges that might built up in the TS1. It is recommended that both the
power and the RS-485 communication cable be ran in metal conduit.

2.3 RS-485 NETWORK WIRING
RS-485 network cable consists of a twisted pair of wires with an outer shield such as
Belden 9463 or similar. The cable is run from TS1 to TS1 with each unit connected in a
daisy chain fashion with no branch or stub runs. Polarity of the twisted pair must be
maintained throughout the entire network. The terminals for the RS-485 connection on
the TS1 circuit board are labeled with polarity marks to help prevent cross wiring. A ter-
minal connection is also provided for the outer shield of the cable.
