5. Place the ramp in front of the starter so that the outside flanges
align with the truck rails inside the cell. Insert the front flange of
the ramp over the edge and into the U-channel at the bottom of
the lower cell. Check that the ramp will not slide left to right or
front to back to ensure that it is properly positioned (see
Figure 12
).

CAUTION
• VERIFY THAT THE FIBER OPTIC HARNESS AND 48V CONTROL POWER
HARNESS ARE BOTH SECURED AWAY FROM THE TRUCK EXIT PATH TO
PREVENT HARNESS DAMAGE.
• PROVIDE AT LEAST 60 INCHES OF CLEARANCE IN FRONT OF THE START-
ER TO ACCOMMODATE THE RAMP AND TRUCK.
• TRUCK APPROXIMATE WEIGHT IS 260 LBS.
• ONCE THE TRUCK DESCENT DOWN THE RAMP BEGINS, THE TRUCK
SPEED INCREASES RAPIDLY.
6. The truck is now ready to be removed. Grasping the upper
glass-polyester pull bars, being careful not to damage the PCB
cards, draw the truck out onto the ramp. Keep both hands on the
truck and brace against it as it travels down the ramp to control
speed (see
Figure 13
).

Alternately, a single pole may be removed without extract-
ing the rest of the truck for rapid replacement. Unbolt the
required pole hold-down plate (see
Figure 11
). Remove the
pertinent fibers and power wires, grasp the top and bottom
of the pole and draw out (see
Figure 14
).
