2.6.1 Low-Voltage Control Wire Connections
Field-supplied four-wire control connection (10-wire on 8-ton units) is required between the outdoor
condensing unit and the evaporator. Refer to Figure 2.5 on page8 ,Figure 2.7 on page10Figure 2.8 on
page11 and electrical schematic (Figure 2.9 on page12 throughFigure 2.10 on page13).
2.6.2 Low-Voltage Control Wire Sizing
Low-voltage wiring should be sized to allow a 1 volt maximum drop due to line resistance between the
evaporator and condensing unit. Use NEC Class 1 or 2 wiring according to wire routing conditions chosen,
local codes and application limits in Table 2.14 above and Table 2.15 below.
