DETERMINING UNIT TYPE
In order to properly mount and wire the KEB Combibox, it is necessary to
identify the type of the unit. To do this, nd the part number of the unit, which
is located on top of the terminal box. It should be in the following format:
XX.YY.ZZZ (Example: 06.10.370)
YY indicates Type as follows:
The clutch rotor transmits the power from the input to the output by making
secure frictional contact with the armature. The armature is fastened to the
output shaft. The arrow on the Combibox housing always points from the
input (clutch side) to the output (brake side). Mount the unit accordingly!
2Combibox Instruction Manual

INSTALLATION & WIRING
When direct DC voltage is supplied
to the Combibox, the terminal strip
shown in Figure 1 will be mounted
in the conduit box.
Polarity in the clutch and brake is
not relevant when wiring type 09,
10, and 16, but it is relevant when
wiring the type 06 Combibox. The
green wire with the red stripe is
positive and the green wire with the
blue stripe is negative.
When AC power is supplied to the Combibox, a rectier will be used in place
of the terminal strip. See Figures 2 and 3 for possible wiring congurations
for a type 09 or 10 Combibox. See Figure 4 for the wiring conguration for
a type 06 or 16 Combibox.
Figure 2 Figure 3
There are two basic rectiers avail-
able for clutch/brake combination:
• 02.91.020-CE07 for 110VAC/
95VDC, bridge rectier
• 02.91.010-CE07 for 220VAC/
95VDC, half wave rectier.
Figure 4
Relays for switching should be
rated at least 250VDC/10A

PERMISSIBLE SHAFT LOAD
The value FNrefers to the load at the middle of the shaft, distance L/2. It
is based on a sercive, life of 10,000 h and a speed of 1500 rpm. For other
speed and service life values, FN can be calculated with the aid of the graph
shown above. If additional axial forces occur, a recalculation of the bearing
load should be performed by the factory.
Example:
Lh= 5000 h, n = 1000rpm
F/FN= 1.5 therefore F = 1.5 x FN
OPERATION & MAINTENANCE
The KEB Combibox is shipped ready for installation with the air gap
preadjusted to the nominal value. NEMA, or IEC mounting dimensions on
the input and output ends allow for easy assembly to motors and gearboxes.
DO NOT FORCE FIT when mounting. An antiseize lubricant should be used
on the shaft when mounting the Combibox. To avoid contamination of the
friction surfaces, do not use excessive amounts of lubricant.
Proper sizing of the Combibox in accordance with the application will
minimize wear and reduce maintenance. The air gap should be readjusted
according to the instructions when it reaches three times its nominal
4Combibox Instruction Manual

PLEASE NOTE: REFER TO PAGE 2, “DETERMINING UNIT TYPE,”
BEFORE PROCEEDING.
• TYPES 09 AND 16 MUST BE RETURNED TO KEB AMERICA FOR
ADJUSTMENT.
1. For type 10, engage the brake by supplying the proper DC voltage to
the brake magnet. For type 06, no power is required.
2. Remove the access plugs from each side of the Combibox.
3. Loosen the two lock nuts (See Figure 5).
4. Insert the feeler gauge between the clutch magnet and the armature.
Tighten the adjusting screws(clockwise) until the nominal air gap is
reached. The air gap should be equal on each side (See Figure 6).
5. Tighten the lock nuts.
6. Screw the plugs back into the access holes.

ADJUSTING INSTRUCTIONS
5

When the Combibox has reached maximum wear, the wear parts must
be replaced. Wear parts include the brake magnet, the armature, and the
clutch rotor. To order spare parts, provide the 11 digit part number, or the
following information:
1. Size and type of unit
2. Magnet voltage
3. Input style of unit (solid or hollow shaft, and bore size)
In order to replace worn parts with new parts, refer to the next page and
proceed as follows:
1. Open the terminal box and loosen all electrical connections to the clutch
and the brake.
2. Disassemble the Combibox housing by unscrewing the four bolts.
3. Replace the worn clutch rotor with the new rotor Avoid any contamination
of the friction lining. The clutch rotor is always on the input side of
the Combibox, the arrow on the housing points from the input to the
output.
4. Replace the armature and the brake magnet with the new parts. Use
LOCTITE when tightening all screws. Clean friction surfaces with
pure alcohol before installation.
5. Wire the clutch and the brake terminals in the conduit box.
6. Assemble the Combibox and adjust the air gap as outlined above.
REPLACEMENT & REPAIR PROCEDURE
ELECTRONIC CONTROLS & ACCESSORIES
KEB Combitron 33.94 Rapid Switch
The combitron 33.94 provides a smooth 24VDC signal to the clutch/brake
unit through activation by proximity switches, photocells, mechanical relays,
etc. The 33.94 briey overexcites the coils, which reduces switching times
for a given load by approximately 2/3’s. Extremely high cycle rates can be
achieved while maintaining the absolute accuracy necessary for complex
motion control applications.
Rectiers
KEB rectiers are the best in the industry and are varistor protected for
maximum safety when switching inductive loads. Bridge and half-wave
rectiers are available for AC or DC side switching.
