2.1 Restrictions on use

VAR00/10 units are designed for operation in
oil (not sealed bearings).

VAR04/14 and VAR05 are designed for dry
operation (sealed bearings).

in the catalogue will invalidate the guarantee.

The suitable ambient temperature for these
units is max. 40°C (Insulation class of 155°C).

E320 clutches are designed for horizontal
mounting. Consult our technical services if other

mounting positions are required.

2.2 Precautions in use and safety measures

During maintenance, ensure that the machine’s

moving parts are stationary and that there is no
risk of accidental start-up. All intervention have to be
made by qualified personnel, owning this manual.

0,25 0,25

Any modification made to the brake without
the express authorisation of a representative
of Warner Electric, in the same way than any use out
of the contrac tual specifications accepted by “Warner
Electric”, will result in the warranty being invalidated
and Warner Electric will no longer be liable in any way
with regard to conformity.

3 Installation

3.1 Transport / storage

Our clutches and brakes are supplied in packaging
guar anteeing a preservation period of 6 months with
land or air transport, or after transport by ship to
neighbouring conti nents (without crossing the tropics).

3.2 Handling

Avoid any impacts on the equipment so as not

to alter their performance.

Never carry the equipment by the electrical

supply cable.

Fig. 1

3.3.1 Installing VAR00/VAR04/VAR10/VAR14

• Center the mobile toothed ring assembly (352) or the

mobile plate (353) on the driven part, then fix it
with screws and lock them

• After adjusting the driving key, mount inductor on

the shaft and fix it axially onto the shaft

It is important to tighten the locking screws from

mobile toothed assembly to the specified torque
(see table 2) or to the mobile plate (353) and secure
them with loctite 243 or an equivalent product.

While assembling the driving and driven parts,

it is essential to note the value J (which is the
distance between tooth heads), see Table 1.

3.3.2 VAR504

3.3 Installing

E320 are delivered with bore / tolerance H7 and keyway/
tolerance P9 according to NFE22175 / DIN6885 /
ISO R773 / BS 4235. The mobile plate assembly (353)
is delivered with bore / tolerance H7. We recommand to
use tolerance h6 for shaft and g6 for the mobile toothed
ring assembly (352).

Important: It is important to prevent inductor
(101) from rotating. It is the customers
responsibility to supply means to prevent inductor
rotating. i.e. retention pin in slot.Check gaps between
the inductor and the retention pin (see Figure 1) :
minimum 0,5 mm gap -1 mm gap at the slot bottom.

The pin should not generate any stress on the bearings.
In case of vibrations, it is strongly recommended to
insert a damping elastic slot between the anti-rotation
device and the anti-rotation slot and to fix the coil’s
cable the nearest of it to avoid whipping.

In the case where two co-axial shafts are
fitted, the recommended setover is 0,05 mm
maximum.

The angular misalignment should not be greater than
0,1 mm over a length of 100 mm. If this is the case,
use a VAR05 (flexible coupling).

Detection discs (aluminium or steel) compatible with
induc tive proximity sensor are provided with unit.

The position of the sensor should not obstruct the
travel of the toothed flange (352) (353).

We suggest to use the inductive sensor (615) provided
by our company, (see technical form).

5 Electrical connection

• After adjusting the driving key, mount the inductor

onto the shaft, then fit the adjusting spacer (526) and
the bearing assembly and finally lock the whole axially
on the shaft.

Sizes 3200 and 6400 : the coupling flange (528) is not
mounted in our workshops. After mounting the u to
thshaft, fit the flange with the screws provided to the
spe cified torque (see Table 2) and secure them with
Loctite 243 or equivalent.

Tightening torque 76 ± 8 Nm 189 ± 18 Nm

Table 2

NB.: VAR05 is delivered with a pre-adjusted airgap.

However check the value J between tooth heads after
mounting. (see Table 1).

E320 units must be supplied with direct current (D.C)
and are equipped with a 500 mm length wire. Polarity
does not affect the functioning.

5.1 Important recommendations

All works on the electrical connections have to

be made with power off.

Ensure compliance with the nominal supply voltage
(inade quate supply causes a reduction in the starting
distance and transmissible torque).

The connecting wires should be of sufficient diameter
to prevent voltage drops between the source and
equipment supplied.

I (A) / L (m) 0 to 10 m from 10 to 20 m

0 to 3 (A) 1,5 mm2 1,5 mm
3 to 6 (A) 1,5 mm2 2,5 mm

Tolerance in the supply voltage to the clutch terminals
+5% / -10% (NF C 79-300).

• Mount the coupling hub (507) onto the second

shaft and lock it axially

• Put the spider (730) inside the coupling flange (528)

• Assemble the driving part with the driven part and

insert the coupling hub with the spider (730)

While mounting the unit, it is essential that you
note value E (elastic coupling mounting),

see Table 1.

4 Maintenance

After continued operation it may become necessary to
change bearings. The inductor bearings are mounted
in a special way, and we recommend returning the unit
back to the factory for replacement.

5.2 Supply

For controlling these clutches, we advise the use of
Warner Electric supply units

Sizes 20 to 3200:

CBC 400-24, CBC450-24
CBC 140-5

Sizes 6400 to 12800:

CBC 140-5

Warner Electric supply units provide protection for coils
and circuits. Where a clutch is used without our supply
units, with switching on the DC, it is essential for the
coil to be protected against surges by a varistor fitted
in parallel.
