NEMA 4X Stainless Steel Enclosure (Order Code 5 4X-SS Option)
LifeGuard protection panels are available in a NEMA 4X stainless steel enclosure. The enclo-
sure includes separate instructions for wall-mounting the enclosure. Refer to those instruc-
tions for more information. Dimensions below are in inches (mm).

HAZARD OF ELECTRIC SHOCK, EXPLOSION, OR ARC FLASH
- Disconnect all power before servicing.
- Observe all local, state, and national codes, standards, and regulations.
A professional electrician, licensed in accordance with local laws and regulations, must per-
form this installation. The enclosure must be penetrated in order to bring the line and load
conductors to the protective circuit. Bender recommends making these penetrations on
the bottom of the enclosure, and the use of NEMA 4X (minimum) fittings to maintain the
environmental rating of the enclosure. The specifics of the installation will dictate further
details.
Install the LifeGuard protection panel in series with the protected circuit. Circuit-conductor
connection varies based on the number of conductors and system voltage. Observe the fol-
lowing requirements during installation:
• Use copper wire only. For models rated less than 100 A, use 60 °C /140 °F (minimum) rat-
ed conductors. For 100 A rated models (or for systems where the required 60 °C conduc-
tor cannot be accepted), use conductors rated for 75 °C (167 °F).
• Disconnect switch, branch circuit protection, and/or overload relay to be provided by the
installer.
