Mounting an end tension insulator to a terminal plate
Tightening the Tro-Reel unit
Pull the Tro-Reel unit tight and tighten the end tension insulator nut snugly.
●
Length of coil spring
●
After completing installation, run the hoist or crane
ten or more times and reconfirm the spring tightening
length.
Failure to do so may cause poor collector arm contact or
separation from wires.
●
After installation, let the hoist and crane travel for
more than 10 times and recheck the tightness of
spring. If this job is not properly done, bad contact or
detailing of collector arm may occur.
1.Insert the terminal plate into the groove of insulator.
2.Mount the cover to the insulator.

Feeding power to the Tro-Reel
Power can be fed from the line end via an end tension insulator.
Connect the power wire to the terminal plate
using a crimp-on terminal.

Terminal screws must be securely tightened.
Failure to do so may cause fire.
Caution
Notes
●
Be sure to mount the special washer.
Failure to do so may cause damage of the insulator.
Notes
●
Set the distance from the bottom surface of the Tro-reel conductor to the
center ofthe collector arm mount rod (not included) to 95mm (in the
center of the conductor cleraner mounting tolerance movable range
95±20mm)
●
Arm must be attached parallel to the Tro-Reel unit without any twisting.
■
Standard installation
●
Two collector arms should be used together (tandem type) for circuit
separation and line swiching, and especially in applications in which it is
imperative that collector arms not be separated from wires. Tandem
collector arms cannot be used horizontally. For horizontal installations,
use a single-type collector arm.
■
Assembly in tandem configuration
●
Collector shoes should be replaced when they
partially wear down to the replacement indication line.
Please exchange the collector shoes ahead of time
when it will be worn out to the replacement indication
line by the time of the next check.

After installation, be sure that the hanger, the Tro-Reel unit and the collector arm are level. Failure to do so may
cause poor collector arm contact.
●
When you want to use the collector arms with centerring horizontally,please contact Panasonic electric Works,Ltd.
●
In a horizontal ways case, be sure to use the horizontal support parts.
Failure,there is a risk of derailment or loose arms collector.
