2.3.3 Ground-mount Installation
LPE enclosures require a pedestal mount kit for ground installation. Pedestal kit part number: 746-146-20
(gray); 746-146-21 (white); 746-146-22 (seafoam green)
NOTE:
Tools and Materials Required (customer supplied):
• Four 3/8-16” (10mm) anchor bolts (Hilti-style recommended)
• Four 3/8” (10mm) size stainless steel washers
• 2' x 2' (.6m x .6m) continuous vapor barrier (e.g. 30 lb. felt, neoprene pond liner,
or a heavy grade tar paper)
• Hammer drill
• 3/8” (10mm) drill bit
• 9/16” (14mm) wrench
• Metal punch
• Mallet or hammer
• Torque wrench
• Tape measure
• 3/8" socket
A 25+ year continuous vapor barrier must be placed between the pedestal and the pad to prevent
moisture ingress and corrosion caused by metal-to-concrete contact.
CAUTION!
Procedure:
1. Place the vapor barrier material on concrete pad.
2. Using the pedestal as a template, mark the vapor barrier material in the locations
of the four anchor bolts holes.
3. Drill 3/8" (10mm) holes through the vapor barrier and into the pad at the four
marked anchor points.
4. Position the pedestal over holes and insert anchor bolts. Torque the anchor bolts
to bolt manufacturer specifications. If Hilti-style bolts are used, torque until head
pops.
5. On the enclosure, remove the three 3/4" (19mm) diameter knock-outs located on
the bottom of the enclosure shelf.
6. Lift the enclosure onto the pedestal. Align the three enclosure mounting holes
with the mounting holes on the top of the pedestal. Secure the enclosure to the
pedestal using the provided 1/4" (11mm) hardware. Torque to 75 in-lbs (8.5 Nm).
7. Trim away excess vapor barrier material.
8. The enclosure is now ready for the utility connection, power module, and
batteries.
