INSTALLATION and MAINTENANCE INSTRUCTIONS

SZ-21DIRECT DRIVE HAZARDOUS DUTY ELECTRIC CABLE REELS

All units are provided with right hand rotation unless otherwise specified. This means that cable is pulled off spool top left or bottom right (spool rotates clockwise to wind cable) when viewing spring end of reel. See diagram on parts page.

Clock-typesprings provide power for automatic cabletake-up.

Spring must be pretensioned at time of installation to insure that tension is applied to cable at all times. A tension adjustment spanner wrench is provided with each reel.

WARNING

Some reels with large or multiple springs are equipped with a ratcheted adjustment wrench. Follow separate instructions for its use. Failure to use ratcheted wrench, on reels so equipped, could result in serious personal injury.

WARNING

Do not attempt to relieve spring tension using spanner wrench. Doing so may result in personal injury.

INSTALLATION

1.Insure that machinery to be serviced by reel is at position closest to reel.

2.Securely mount reel in desired position using 3/8"(M10) bolts. Be sure spool is aligned with cable run.

3.Position optional cable guide, if reel is so equipped.

4.Connect free end of cable to junction box on machine or adjust cable stop so that desired length of cable extends from reel.

5.Remove cover plate on spring housing to expose shaft and spring hub. (See Figure 1).

6.Insert spanner wrench into holes in spring hub (Fig 2). Rotate wrench counterclockwise (for standard rotation). Number of 360O turns should match last digit in model number on serial plate.If model number includes an “R”, reel is reverse rotation and wrench must be rotated clockwise. (See EXPLANATION on parts list page.)

CAUTION

Do not exceed number of turns indicated on serial plate. Over-tensioningcan cause a broken spring, sheared shaft or other damage.

NOTE: If reel is equipped with ratcheted adjustment wrench, follow instructions on separate sheet.

NOTE: On reels containing more than one spring, the hubs are connected at the factory. Therefore, by tightening the outer spring, the inside spring(s) will be tightened.

7. Remove collector cover and connect individual supply conductors to collector terminals.

MAINTENANCE

Periodically: A. Use compressed air to clean collector assembly and inside of collector housing. Inspect collector assembly for brush wear and pitted slip rings.

B. Inspect cable for wear and check mounting bolts and

other hardware for tightness.

C.Check for broken springs

by pulling about 2/3 cable off

reel and observing “Broken

Spring Indicators” on sides of

spring canisters. See Fig. 3.

NOTE: Bearings and springs are prelubricated and require no periodic maintenance.

SPRING REPLACEMENT

WARNING

Do not attempt to remove spring from its housing. Clocktype springs can be dangerous to handle. Removal of spring from housing could result in personal injury.

The unique SAFETYCHANGE® spring motor consists of a spring and hub sealed within a housing. A replacement spring is supplied sealed in its housing and the old unit should be discarded completely.

1.Turn off all electric power.

2.Disconnect cable from machine junction box.

3.Wind all cable onto reel to relieve all spring tension.

4.Remove inspection cover from face of spring housing.

5.Rotate spool clockwise and observe inner shaft. Shaft should rotate clockwise and hub (with spring attached)

should remain stationary.

NOTE: Do not attempt to remove spring if resistance is met or hub tends to rotate with shaft.

Continue to rotate spool and strike end of shaft several sharp blows with a lead hammer or rubber mallet

until shaft rotates freely and hub remains stationary.

6.Remove (4) nuts which secure spring motor(s) to frame.

7.Slide spring motor(s) off shaft and discard.

NOTE: Onmulti-springreels, be sure to remove andsave dowel pins which connect one spring hub with another. Also remove snap rings on shaft between spring housings.

8. Install replacement spring motor(s), pawls and pawl springs. NOTE: Pawl springs must be located between the pawls and the deepest section of the shaft grooves. Make sure that pawls and pawl springs are inserted flush with ends of

shaft and hub or they may rub against inspection cover.

INSTALLATION section.

12.Replace inspection cover.

CABLE INSTALLATION & REMOVAL

Use the procedure detailed on HAZARDOUS DUTY CABLE REEL SEALING INSTRUCTIONS (bulletin 039789) which comes with sealing kit (available separately).

CAUTION

Carefuly read and follow instructions supplied with separate sealing kit as well as instructions for sealing compound. Failure to properly follow those instructions could result in damage to equipment, personal injury or death.

CABLE REMOVAL

CAUTION

Always open all breakers and disconnect electrical power to reel. Failure to turn off electrical power could lead to serious injury or death.

1.Move machine serviced by reel to a position closest to reel. Springs will still be under pre-tensionat this point.

2.Turn off all power to reel.

3.Remove collector cover and gasket.

4.Disconnect electric leads to and from collector.

5.Follow Steps 3–9,REMOVING OLD CABLE,

on bulletin 039789.
