2 Precautions and restrictions on use
2.1 Restrictions on use
If maximum rotation speeds are exceeded, the guarantee is no longer valid.
2.2 Precautions in use and safety measures
During maintenance work, ensure that the mechanism to be driven by the units is at rest and that there is no
risk of it being started accidentally. All intervention have to be made by qualified personnel, owning this
manual.
2 Warner Electric Europe • +33 (0)2 41 21 24 24 P-2073-WE • 11/12
Any modification made to the unit without the express authorisation of a representative of Warner Electric,
in the same way than any use out of the contractual 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
These units are delivered in standard packaging that will keep it intact for a period of 6 months during
ground, air or sea transport towards neighbouring continents (without crossing the tropics).
3.2 Handling
Avoid any impact on the units so as not to alter their performance.
The hub (515) is normally supplied at tolerances H7 for the bore and P9 for the width of the keyway (In
accordance with NF E 22-175/DIN 6885/BS 4235/ISO R773).
We recommend a tolerance h6 for the shaft. Slide the hub (515) on the shaft (after adjusting the keyway).
Never directly strike the hub (515), use a soft alloy part between these parts and the assembly device used.
Fix then the hub with socket cap head screws or bolts.
After tightening to torque, do not forget to secure the bolts fixing the hub (508) with Loctite 243 or an
equivalent type of product.
3.3 Setting up
The adjustment of the limiter to a given torque is obtained by displacement of the pressure flange ( 362), by
action on the axial fixing screws (905), after having loosened the setting screws (902).
• higher torque : moving the flange toward the interior
• lower torque : moving the flange toward outside
Check that dimension “Z” between the pressure flange (362) and the face of the hub (508), is adjusted a
tolerance of ± 0,1 mm.
Ensure, by some manoeuvres, that the slip torque is in line with the requested value.
Going beyond the value of dimension “Z max.” (Table 1), could generate a blocking of the limiter and a risk of
danger for the operator.
During maintenance work, ensure that the mechanism to be driven by the units is at rest and that there is no
risk of it being started accidentally. All intervention have to be made by qualified personnel, owning this
manual.
