RSD10 / RSD20 / RSD50 / RSD100
The spur gears of the RSD10 / RSD20 / RSD50 and RSD100
(Contrac) actuators are oil lubricated. When delivered, the
actuator is filled at the factory with the oil volume in accordance
with IMV 1. Once the actuator is installed replace the uppermost
check plug by the separately supplied venting plug.
The mounting positions shown in Figure 6 and Figure 7 are
permissible. To facilitate mounting and maintenance, however, it
is recommended to use orientation IMV 1. For each mounting
position, you should check the specified oil level before
commissioning, see Filling volumes on page 34.
Note
Maintain a minimum distance of 80 mm (3.15 in) to ensure
sufficient cooling air supply and for possible module
replacement.
