Control wiring
A minimum of 16 AWG should be used between the power supply
and the 24 Vdc + and – terminals.
Terminal connections are to be secured to a torque value of 3.6 lb-in.
Control wiring is connected to the DS6 soft start controller by a
9-pin terminal block located on the front of the unit. Use the wiring
diagrams in
Figure 4
,
Figure 5
, and the information in
Table 7
as guides.
