Model GR900 retracts up to 40 feet of #1/0 or #2/0 AWG grounding cable intended to protect equipment and personnel in
the event of a ground fault. The collector rings’ electrical path through the reel has a current carrying capacity greater
then that of the largest cable (#2/0 AWG) to be installed on the reel.
WARNING:
Failure to lock the cable drum in position with the cable fully extended as instructed, will
create an explosion hazard in the even of fault condition, and may result in property damage,
personal injury, or death.
WARNING:
The internal electrical path is not insulated from the reel frame, therefore, this reel is
unsuitable for other uses other than retracting ground cables. Use for other applications will
create an electrical shock hazard, and could result in property damage, personal injury, or
death.
WARNING:
Failure to install, operate, and maintain the retractor in accordance with these instructions
may result in electrical shock causing property damage, personal injury, or death.
WARNING:
If ground fault has occurred, return the reel to Aero-Motive Company for inspection , and
possible repair before placing back in service. Failure to do so could result in electrical
shock hazard, and may result in property damage, personal injury, or death.
Installation
CAUTION:
Misalignment of the reel and cable travel direction will cause the cable to be deflected at a
sharp angle around the cable guide rollers
CAUTION:
The reel should be bolted securely to a flat metal surface of sufficient strength and rigidity to
support it under all conditions to which it will be subjected. Mounting holes will
accommodate 7/16” or 3/8” bolts. Nothing smaller then 3/8” or 10mm bolts should be used.
