CHAPTER SIX
SECTION 6.0
DIRECTOR 2 EHU (continued)
MOUNT THE DIRECTOR 2 EHU ONTO THE BOOM
Refer to the center-to-center measurements in
Chapter Two
when installing each of the EHU’s and mounting
plates to the boom. The EHU should already be wired before placing it on the aluminum mounting plate.
Position the aluminum mounting plate (PN 10-1015-11) and align the 1-3/4” aluminum saddle halves
(PN 10-1601-03) as shown in
figure 6.02
. Insert the 5/16” x 3-1/2” hex head bolts (PN 60-0065) and
thread on the 5/16” Nylock nuts (PN 60-0046). Insert a set screw on the exposed side of the aluminum
saddle. Tighten, but allow the mounting plate to be loose enough for adjusting the center-to-center meas-
urement. Be sure to use anti-seize on all stainless steel fasteners.
Figure 6.03
shows the mounting plate
attached to the boom.
Place the EHU gasket (PN 10-1502-01) onto the mounting plate as shown in
figure 6.04
. Align the gasket
with the holes on the mounting plate. Place the Director 2 EHU (PN 70-3422-01) onto the mounting plate
as shown in
figure 6.05
and attach using the #10 x 3/4” machine screws (PN 60-0017), #10 flat washers
(PN 60-0018) and #10 Nylock nuts (PN 60-0019) as shown in
figure 6.06
. Be sure that the flat washer is
between the machine screw head and the EHU housing as shown in
figure 6.07
. Tighten the Nylock nuts
enough to compress the gasket material but do not over tighten or you can crack the plastic EHU housing.
Measure the proper distance from the center-point of the element to the right edge of the boom (4.375
inches) as shown in
figure 6.08
. Be sure to check your center-to-center measurements from the Director 1
EHU to the Director 2 EHU (171.75 inches).
Level the EHU as shown in
figure 6.09
and tighten the alumi-
num saddles firmly.
