WARNING
Hazardous Voltage -Installing low and high voltage wire in same conduit could cause electric shock or burns,
resulting in death or serious injury.
• Do not run low and high voltage wire in the same conduit unless the insulation rating on ALL wiring is rated for 600V.
See NFPA 70 for more information.
Low Voltage connections are made via a field connection terminal block (E) in the main electrical area. Compare this
illustration with your generator to familiarize yourself with the location of these connections.
A •Two Pin Terminal Block — Used to connect utility 240 VAC from fuse block in ATS to the control board. Connect only one
wire per terminal. Use #14 [2.5mm2] AWG minimum 300 volt wire.
B •Power Connection (Line 1 and Line 2) — Power connection to transfer switch.
C •Ground Connection — Connect to transfer switch ground wire.
D •Neutral Connection — Connect to transfer switch neutral wire.
E •Reference the table that follows:
