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.
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 brakes are supplied in packaging
guaranteeing a preservation period of 6 months
with land or air transport, or after transport by
ship to neighbouring continents (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.
3.3 Installing
For installation on the support or frame, it is
essen tial to proceed as follows, (see appendix).
• Compress the springs by putting the chamber
under pressure (see chapter 5), the moving
armature (330) should be in contact with the
cylinder (401)
• Remove the fixing bolts (909), the friction plate
(348), the friction disc(s) (312) and the interme
diate disc (320) in the case of dual disc brakes
• Slide the hub (515) onto the shaft to be braked,
adjust
the drive key and stop it axially by the
means provided
Do not oil the guide splines (friction disc / hub) or
performance will be affected.
WARNING: It is essential that the hub is assem-
bled in the right way round (See fig 1 above)

The hub is normally supplied to tolerance H7
on the bore and P9 on the width of the key-way
(In accordance with NF E 22-175/ DIN6885/BS
4235/ISO R773).
• Locate the friction plate (348) on the support.
Then fit the friction disc (312) and in the case
of a dual disc brake (P620), the intermediate
disc (320) then the second friction disc (312)
NB: The collar on friction discs must face the
friction plate (See figure 1).
• Put the moving armature assembly (330) /
cylinder / piston (401/402) between the lugs of
the friction plate (312) then fix the assembly by
means of the bolts (909) and washers carefully
tightening to the correct torque (see table1)
• Put the equipment under pressure (see chapter
5) and check that the disc rotates freely
• Make several movements, motor stopped, and
check the value of the nominal airgap (see table
1) near the friction plate lugs (348)
• In the event of insufficient travel, refer to
chapter 4 (maintenance)
