INSTALLING THE SHALLOW BASE
Two different installations are possible:
Method “A” –
cable leads to be laid in wireways
Method “B” –
cable leads to be laid in cable ducts (Figure 14)
Proceed as follow to realize a proper installation.
STEP A

ACTIVITY DESCRIPTION
1
Take the base from the shipping box.
2
To assure an adequate bond between base and hole all external surfaces of
the base should be sandblasted and must be cleaned with solvent.
TAKE CARE
NOT TO DAMAGE THE ELECTRICAL SYSTEM.
3
/
Connect an insulated G/Y grounding wire of suitable length to the grounding
screw externally provided on the wall of the base.
4
/
Splice the light base leads to the power cables using solderless squeeze
connectors, as shown in the figure, crimped with the proper tool. Connect also
the grounding wire to the main grounding network by using a suitable
clamping lug.
ATTENTION: Insulate each splice carefully using either heat shrinkable
insulating tubing properly applied or at least three layers of plastic electrical
insulating tape applied with half overlap.
5
Mount the positioning jig (P/N 332.4301) on the base as shown in Figure 15.
An optical device for proper fixture orientation is available (P/N 332.4351
6
/
Properly arrange the leads in the wireways using small pieces of insulating
tape if necessary.
7
Completely cover the bottom of the base with sealer material, apply a thin
coat of sealer to the bottom of the drilled hole to assure a bond between the
