MOUNTING
Standard
mounting
1. The reel may be mounted by bolting the base to any flat surface which is structurally sound enough to support it and
the forces of winding and unwinding the cable.
2. The spool drum must rotate on a level horizontal axis.
3. Position the guide arm so that cable payout is perpendicular to the face of cable roller guide. The total cable deflection
should not exceed 15° to either side of the centerline of the spool.
4. If deflection is constant to either side of the reel and operation is impaired, re-mount the reel.
5. If the angle of deflection exceeds a Pivot Base should be used, otherwise excessive cable wear and unreliable
operation will result.
6. A safety chain is recommended for all overhead installations. Attach the safety chain using the 0.39 hole provided in
the base.
Pivot Base
mounting
1. All EXPCRL cable reels can be furnished with a spark proof pivot base to allow the reel to rotate and keep the
extended cable perpendicular to the application.
2. The pivot base has the ability to rotate up to 340°. This pivot base is not suitable for applications requiring continuous
rotation.
3. A pivot base is required carousel or loop-track applications.
4. When a pivot base is used, the reel must be mounted horizontally (ceiling or floor mounted).
5. The roller guide should be mounted so the cable will travel perpendicular to the axis of rotation. This will guard against
the cable twisting and ensure effective swivel action from the pivot base.
6. Selection of mounting holes should be such that the spool center is in line with the center point of the pivot base.

Roller guide
1. All EXPCRL units are equipped with a roller guide arm. The function of the guide is to center the cable on the spool
and to help the reel cable more evenly.
2. The cable should not pile against either end of the spool during winding as this will tend to inhibit level winding of the
cable.
3. The guide should be secured at the best of twelve possible positions so that a minimum change of direction occurs at
the guide; otherwise, cable life will be reduced.
4. The guide is shipped installed on the reel. The guide must be aligned per application and secured prior to making any
electrical connections.
5. Mount the roller guide to the reel over the entrance coupling on the frame. Secure using the provided 3/8-16 hex head
cap screw, including the split lock washer. Tighten this to 15 ft.-lbs.
