The screws (please refer to Figure 27 Pos.7
ETH100&125; see Figure 28, Pos7) must be screwed in without torque, so that
the drive unit can be lifted upwards.
Loosen both lock nuts (please refer to Figure 19 Pos.14; ETH100&125) (do not
remove entirely).
Unscrew both threaded pins (please refer to Figure 19 Pos.10; ETH100&125)
until they are almost level with the inside of the parallel housing.
Tighten central toothed belt tensioning screw (please refer to Figure 19 Pos.12)
until the toothed belt is noticeably pretensioned.
Measure toothed belt tension with a suitable device.
We recommend: Gates: "Sonic 507c" or Hilger&Kern: "Trummeter"
Thighten tension screw slightly and measure again.
Repeat this procedure until the required toothed belt pretension (see page 42) is
set.
Only a correctly set toothed belt pretension ensures fail-safe operation of the
cylinder.
Screw in both threaded pins (please refer to Figure 19 Pos.10) until they touch
the inner bracket. Tighten pins slightly.
ETH100 & ETH125 Motor/gearing installation: Now the motor/ gearbox (see page
30) must be installed. In this case, the screws, Figure 28, Pos7 still have to be
loosened easily. After the motor/gear assembly and before the gradual final
tightening of the clamping bushing (see Figure 25Pos 20; Figure 26Pos 20a) the
four screws, see Figure 28 Pos7, must be fully tightened (screw tightening
torques see Table 3).
ETH032…ETH080: Completely tighten the four screws (please refer to Figure 27
Pos.7. screw tightening torques and Table 3.)
Reassemble the vocer
ETH032…ETH080: please see Figure 19 Pos 4 & 6 with screws Pos 11 & 9
ETH100 & ETH125: please see Figure 38 Pos 4 & 6 screws Pos 11 & 9.
2.3.3.
IP65 motor mount
For the IP65 option, we generally recommend to have the motor mounted by
Parker. If the motor is not mounted by Parker, please respect the following
instructions to achieve the best possible sealing effect.
2.3.3.1
Motor mounting for IP65 inline
The cylinder is furnished with mounted coupling housing and motor flange. Before
mounting the motor to the flange, it must be sealed as follows.
Apply silicone sealing compound to the motor
flange pilot (e.g. Sista Silicone F109 Universal).
Screw motor to motor flange
(see chapter “Motor and gear assembly” (see page
23)).
Note the additional mounting steps
(see chapter “Motor and gear assembly” (see page

IP65
