8.1.3 No frame
1. Attach the lifting brackets to the recloser
(GridShield
®
3P single tank). Lift the frame off
the pallet and place it in the desired position.
For 3SP units, use lifting straps around each
individual pole body.
2. If a different bracket provided by the customer
is used to mount the recloser, be careful while
lifting it. Avoid lifting the single-tank recloser
by the poles to prevent any damage to them.
8.2 Grounding
Grounding is crucial to ensure the proper
functioning of electronic components and
to prevent the intrusion of EMC noise and other
transients into sensitive electronic circuits, such
as relays, modems and radios.
In the single-tank recloser cabinet, you will find a
standard NEMA 2-hole drilled, unpainted stainless
steel pad at the back for grounding (refer to figure
31). In 3SP units, each pole bucket has a grounding
point located underneath (refer to figure 32).
If voltage transformers are being used, they should
be grounded to the main ground wire that leads
from the recloser to the ground.

33 Grounding on back
of LV control cabinet
To ground the low voltage control cabinet (refer
to figure 33), use the provided connector (found
in the shipping bag within the control cabinet).
This connector can accommodate a #6–2/0 AWG
conductor. Connect the control cabinet to the main
ground wire using this external connector. Ensure
that all ground wires used are minimum #4 AWG.
Both the high voltage cabinet and low voltage
control cabinet should be firmly grounded
in series when installed.
