HAZARD
- Disconnect all power before servicing.
OF ELECTRIC SHOCK, EXPLOSION, OR ARC FLASH
- Observe all local, state, and national codes, standards, and regulations.
A professional electrician, licensed in accordance with local laws and regulations, must
perform 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.
Connect
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
following requirements during installation:
• Use copper wire only. For models rated less than 100 A, use 60 °C /140 °F (minimum) rated
conductors. For 100 A models (or for systems where the required 60 °C conductor cannot
be accepted), use conductors rated for 75 °C (167 °F).
• Disconnect switch, branch circuit protection, and/or overload relay must be provided
separately.
