The PN-3 or PN-4 cabinet as shipped weighs approximately 100-150 lbs. A safe means of transportation to the site and a
safe procedure for unloading the enclosure is necessary. Do not transport or lift with a device that may not be able to bear
the unit's weight, and do not place the unit upon a surface that will not be able to fully support it.
NOTE: Enclosure must always remain in the upright position during the shipping, storage and installation
process. Damage may result from enclosure being shipped or stored on its side.
NOTE: Electronic modules, batteries or other components must not be installed until the enclosure is securely
set in place at its permanent location.

3.1 Transportation and Lifting
3.2 Enclosure Mounting Procedure
The enclosure bolts directly to the concrete pad. Mounting holes are provided in the base of the internal enclosure rack to
accommodate the pad’s 3/8" stainless or galvanized anchor bolts.
1. Place vapor barrier material on pad and make cutouts for anchoring hardware and other openings as
necessary. A 25+ year vapor barrier MUST be used between the concrete and enclosure base to inhibit
moisture ingress and to prevent corrosion caused by concrete-to-metal contact.
2. With no less than two field personnel lifting the enclosure, position it above the concrete pad and slowly
lower it into position over the pad's 3/8" anchor bolts.
3. Secure the enclosure using stainless, galvanized (or better) flat washers, lock washers and 3/8" nuts at
each mounting bolt.
NOTE: Enclosures must be mounted flush with a smooth surface. If the concrete pad is uneven or has
bumps, cracks or other imperfections, the installer is responsible for correcting these defects prior
to installing the enclosure.
4. Install electronic modules and batteries at this time.
