to be guaranteed before they are put into storage.
The devices may be stored under moist and corrosive conditions
for a short time. The equipment is protected against external
corrosive influences. However, direct exposure to rain, snow,
etc., must be avoided.
The permissible storage and transport temperatures must be
observed.
Devices equipped with a heater are also protected by desiccant,
which is placed in the following locations where condensation
may be a problem:
Position sensor: In connection chamber
Electronic unit In electrical connection chamber
The desiccant guarantees sufficient protection for
approximately 150 days. It can be regenerated at a temperature
of 90 °C (114 °F) within 4 h.
Remove the desiccant prior to commissioning the actuator or
the electronics.
If you intend to store or transport the device for a prolonged
period (> 6 months), we recommend that you wrap it in plastic
film and add desiccant.
Protect uncovered metallic surfaces with an appropriate long-
term corrosion inhibitor.
The relevant long-term storage temperatures must be observed.

accordance with EN 60068-2-6, Table C.2 to 150 Hz and max.
2 g.
• The substructure should be designed to be level and torsion-
resistant.
• When mounting the actuator close to heat sources use an
insulating layer or shielding.
• Make sure that the maximum ambient temperature is not up-
scaled. If required, provide a sunshield to protect against
direct sunlight.
Fastening the actuator
1.Place the actuator on the fastening device in the correct
position. Pay attention to the rotating direction in
combination with the final control element.
2.Fasten the actuator using four screws. Use the biggest
possible screw diameter and observe the tightening torque
(see table Locking and fastening elements on page 12).
Mounting position
The spur gear of the actuator RHD8000 / RHD16000 (Contrac)
are lubricated with oil. When delivered, the actuator is filled at

Safety instructions
WARNING
Risk of injury due to live parts!
Risk of death or serious injuries due to electricity and
unexpected machine movements. In automatic mode the
motor is always under power, even at standstill.
• When working on the actuator or the related subassembly,
switch off the supply voltage for the electronic unit and
separate anti-condensation heater (option), and take
precautions to prevent unintentional switch-on.
The electrical connection may only be established by authorized
specialist personnel.
Notices on electrical connection in this instruction must be
observed; otherwise, electric safety and the IP-rating may be
adversely affected.
Safe isolation of electric circuits which are dangerous if touched
is only guaranteed when the connected devices fulfill the
requirements of EN 61140 (basic requirements for secure
separation).
To ensure safe isolation, install supply lines so that they are
separate from electrical circuits which are dangerous if touched,
or implement additional isolation measures for them.
Each actuator requires a suited Contrac electronic unit with
installed actuator-specific software. Observe the information in
the operating instruction. The specifications on the name plates
of the electronic unit and actuator must match to guarantee
correct hardware and software allocation.
