!WARNING
ELECTRICAL SHOCK HAZARD
Failure to follow this warning could result in personal injury or death.
Do not use gas piping as an electrical ground. Unit cabinet must have an uninterrupted, unbroken electrical ground to minimize the possibility of personal injury if an electrical fault should occur. This ground may consist of electrical wire connected to unit ground lug in control compartment, or conduit approved for electrical ground when installed in accordance with NEC (National Electrical Code); ANSI/NFPA 70, latest edition (in Canada, Canadian Electrical Code CSA [Canadian Standards Association] C22.1), and local electrical codes.

If the field disconnect is larger than 100A, it must be attached to the unit using accessory CRDISBKT001A00
—disconnect switch bracket — (see Fig. 28). Follow the instructions provided with this accessory. For smaller field disconnects, be sure to use 1/2” screws to mount the disconnect directly to the end panel (see Fig. 29). In either case, set the disconnect vertical location on the unit so that a 90_ fitting can be used to connect the conduit to the disconnect.
