Installation on a User-Furnished Structure

Step 4

Position the pole-unit so that its base is near
the pole-unit mounting bracket. If necessary,
rotate the pole-unit so that its electrical junction
box and terminal-pad attachment locations are
appropriate for the installation. See Figure 6.

NOTICE

The terminal pad of each pole-unit can be
mounted in one of four positions located 90°
apart . Determine where terminal pads will be
attached before mounting the pole-unit .

Step 5

Remove the shipping brace from the pole-unit
base. See Figure 7.

Ç

CAUTION

DO NOT rest the pole-unit on its base

after the shipping brace has been removed .

Damage to the operating shaft can

occur.
