Sealing Primary Equipment Compartment Cable Entries
In keeping with local practices, seal all cable grommets and cable entry points.
It is extremely important to maintain a well-sealed enclosure primary equipment compartment. Failure to do so can jeopardize the
enclosure sensitive electronics, as well as the proper functioning of enclosure systems. All cable interfaces into the primary
equipment compartment must be properly sealed after installation of cables.
Conduits Enter the Rear Lower Access Panel or Cabinet Sidewalls Option: No enclosure pre-preparation required, except planning for
the conduit runs to the enclosure. It is advised to use LB pull boxes at the enclosure connection to facilitate easier cable pulling. If
adjacent LB pull boxes interfere with each other because of conduit routing, it is advised to add a conduit extension off the panel to
push one of the LB boxes away from the panel.
If individual cables are being routed directly into the enclosure, straight male watertight cord connectors may be used within the
different knockouts. Cables up to 1.88"DIA may be used in cord connectors for the 2" trade-size knockouts (ref Hubbell p/n's
SHC1065 - SHC1069). Use the correct cord connector for the diameter of cable being passed into the enclosure.
Conduits Enter the Bottom Panel of the Enclosure: The knockouts in the bottom panel of the enclosure are to be removed as needed
so that conduits can be run to the conduit plate and secured with conduit fittings.
•
See “Removing/Installing Rear Access Panels” on page 22 to remove the rear access panels.
•
Disconnect the bonding cable from the bottom rear access panel (2-hole lug) and set the panel aside.
•
The top and middle rear access panels can be re-installed for enclosure installation.
The battery box cable entry fittings have internal rubber collars to aid in sealing against the cables, but additional sealant and/or tape
may be required to provide an acceptable seal.

Grounding the Enclosure
ALERT!
Grounding should be accomplished according to local practices and in accordance with the latest NEC codes.
All enclosure grounding and ground ring must be installed prior to turn up of enclosure.
•
The internal enclosure frame and all attached equipment are factory grounded to the enclosure Master Ground Bar (MGB).
•
Two ground ring termination blocks are provided at the lower rear of the enclosure. A 2 AWG lead is factory connected from
the enclosure Master Ground Bar (MGB) to one of the ground ring termination blocks. The second ground ring termination
block is also factory connected to the first with a 2 AWG lead.
•
The external enclosure shell is internally grounded to the ground ring termination blocks.
The enclosure should be grounded to an external ground ring using a 2 AWG solid wire. The resistance of the ground ring, as verified
with a Megger, shall be less than 25 ohms. Refer to “Site Ground” on page 28 for supporting information.
Procedure
1.
Connect a ground ring termination block to site ground per local practices. Refer to Figure 8.1 for location. Refer also to
Figure 6.1. The ground ring termination blocks are equipped with 1/4-20 studs on 5/8” centers for installation of customer
provided lugs. Refer to Table 5.1 for recommended lugs. Recommended wire size is 2 AWG.
Alternatively, two ground ring termination blocks are provided, enabling the enclosure to be "daisy-chain" bonded into a
series of enclosures utilizing only one (1) earth-ground link for the entire enclosure set.
