Communication Wiring; Wires To Unit - Bard FUSION-TEC HR58APA Installation Support Materials

208V taps are: 240V Tap (253 – 216) and 208 Tap
(220 – 197).
NOTE: The voltage should be measured at the field
power connection point in the unit and while
the unit is operating at full load (maximum
amperage operating condition.

Communication Wiring

For low voltage wiring, 2-wire 18 gauge shielded with
drain is recommended.
From the controller, extend the shielded cable through
a separate conduit and route to the terminal block
mounted on the wall-mount unit next to the control
board (see Figure 1.12).
Note that the terminal block label is clearly marked "+"
and "-". These connections are polarity-sensitive. Two-
wire communication from control board is prewired to
terminal block. Make sure to match "+" and "-" symbols
on controller terminal block.
Make small service loop in cable and attach EMI filter
(included) as shown if unit is last in communication
chain. See LV1000 controller manual 2100-673 for
complete information on connecting the wall units to
the LV controller.
