2.7.2 Uncoil the 20 ft. control cord. Rotate the power
unit drum switch to the “REV” position. Since the
system is not latched, the LD ring will lower. Do not
lower to less than four feet above pole base. (For
complete operating instructions refer to Section III of
this manual). Pull on the rope if it is necessary to bring
the LD ring down smoothly. After the ring is down,
remove the slotted washers off the pins and remove the
rope. Turn off the circuit breaker.
2.7.3 Route luminaire cords from Junction Box, around
ring and through the arms.
2.7.4 If optional Fixed Wireway Covers are included,
install as follows:
2.7.4.1 Loosen luminaire mounting arms from ring.
2.7.4.2 Mount Wireway Cover, with notch for strain
plate, to left of the Junction Box Arm by slipping cover
between the ring and the arms.
2.7.4.3 Mount other covers between ring and arms.
2.7.4.4 Re-tighten arms to ring. (See Figure 21)
2.7.5 Mount and wire the luminaires, one per arm,
according to the instructions supplied with the lumi-
naires. Install the proper lamps.

2.8.2 Disconnect the circuit breaker cord from the power
inlet on the junction box and connect it to the drive motor
or transformer, as required. Turn on the breaker. The
device, complete with luminaires, is now ready to be
raised to the top of the pole.
2.8.3 Following the operating instructions of Section III,
raise the ring and luminaires to the top of the pole,
stopping just before the wooden cable markers contact
the latch barrels.
2.8.4 Carefully move the device upward until the three
markers are just touching the latch barrels. At this
point, move the ring upward another foot. This causes
the markers to slide down towards the latch pins and to
become positioned relative to the latch barrels.

2.7.6 When included, mount the counter-weight to the
lowering ring adjacent to the junction box using the
stainless steel bolts and nuts supplied. (See Figure 18)
2.7.7 Plug the circuit breaker cord from the circuit
breaker into the power inlet on the junction box and turn
on the circuit breaker. Check for proper operation of
the lighting fixtures. Turn off the circuit breaker.
WARNING
Do not break and make the circuit with the plug and
connector. Use the circuit breaker. Failure to use the
circuit breaker may result in electrical shock.
2.8 Latch Synchronization Adjustment
2.8.1 Attach a wooden cable marker assembly to each
hoisting cable with its top at least 36 in. above the top
of the latch pin. Bolt the two halves only tight enough
so that the marker can be moved down the cable when a
30 or 40 lbs. force is applied. Also center the marker
and keep its top edge square with cable. (See Figure
22)
