I.
INSTALLATION OF REEL
A.
MOUNTING: Reel may be mounted base up, base down, or in any position which allows the mainshaft to be
horizontal. Reel should be mounted with centerline of drum in line with cable run.
B.
PIVOT BASE: If optional pivot base (BK-43) is used, reel will be self-aligning to direction of cable run. The
four-roller guide (BK-53) must be used with pivot or swivel mounts.
C.
WIRING: Input power connections are made at terminal board (BK-47) through a connector or coupling which is
inserted into the 3/4 inch pipe thread opening at the bottom of the enclosure. Due to various types that may be
used, this connector is not supplied with reel. Individual conductors are then connected to open side of terminal
board (BK-47).
D.
SAFETY INTERNAL GROUNDING: Standard reels are not grounded internally with the exception of reels built to
C. .A. standards and the model 228a-H. Internal grounding must be accomplished by the user by running one
jumper wire from brushholder (BK-21) to screw(s) (BK-32) and a second wire from terminal (BK-47) to screw(s)
(BK-48).
E.
SECONDARY SAFETY CABLE: It is strongly recommended that a secondary safety cable or chain be attached
to all reels mounted overhead to prevent reel from falling.
II.
ADJUSTMENT
A.
RATCHET LOCK: All models are supplied with a ratchet lock which works in any position. If ratchet lock is not
required (constant tension), place lock adjustment plate in position shown in illustration on opposite side. For
ratchet lock action, move plate to position shown with phantom lines.
B.
CABLE GUIDE: The cable guide arm (BK-1) may be set at any fixed position around the cable drum. The
guide (BK-53) must be set so the cable pays off reel in a straight line without bends. If guide arm is to be free-
swinging (self-aligning), loosen screw (BK-2) on base of guide arm.
C.
SPRING TENSION: Before making final connections of cable (BK-18), pretension reel by pulling cable out far
enough to allow one full wrap of cable to be thrown back over spool, hold spool from turning, and place cable
back on reel. Repeat until desired tension is set. After tension is set, pull cable out completely to insure enough
spring travel remains for operating. Failure to test in this manner can lead to spring damage. Failure to
pretension the reel may shorten the life of the spring. Caution: Always check for shorts and continuity before
turning on electrical power.
