Grounding Instructions
The FW-X240’s metal mounting bracket must be connected to a permanently grounded
system. System grounding as required by the National Electric Code, ANSI /NFPA 70-1996, is the
responsibility of the system installer.
• The FW-X240 hardware kit includes grounding washers to penetrate a powder-coated  nish,
assuring a proper ground connection to any FLEXware enclosure or mounting plate.
• An installation might call for an optional grounding wire between the FW-X240 and the FLEXware
enclosure or mounting plate to which it’s attached depending on local code requirements or the
nature of the installation itself.
Connections
• No additional terminals or lugs are required for hook-up of the AC wiring.
• AC wiring must be no less than 10 AWG gauge copper wire, rated for 75 degrees C or higher and
must be sized appropriately to the circuit breaker.
Hardware Kit
The FW-X240 comes with four M6 X 20 mm screws, four  at washers, and four grounding washers for
mounting to a FLEXware Mounting Plate from inside a FLEXware AC enclosure.
