Series 6A Operation & Maintenance – field Connections

6A O & M : 6

fIelD WIrInG

Each S6A is provided with two conduit entries for power/incom-

ing analog signal of the main unit and any optional modules.
Please refer to the wiring diagrams referenced in this docu-

ment when connecting the positioner and any optional modules.

It is essential to install the optional modules before connect-

ing the positioner electrically. Refer to the following “Technical

Description” portion of this manual for relevant power distribu-

tion sizing information when installing a S6A positioner and its

optional modules.
Safety Notes:

• Local regulations regarding hazardous environments must be

followed when installing this device in a hazardous location.

• The conduit connections must be properly sealed to maintain

the weatherproof integrity of the actuator enclosure.

• Never connect the current input (terminals 6 and 7 as shown

on the diagrams to the right) to a power source; the positioner

will probably be destroyed in that case. Always use a current

source with a maximum output current of I = 20 mA.

• To maintain auxiliary power, the input current must be a min-

imum of 3.6 mA.

Note: The plastic enclosure is metallized from inside to

increase the electromagnetic compatibility (EMC) with

respect to high-frequency radiation. The shield is connected

to the threaded bush shown in Figure 1 such that it is elec-

trically conductive. This protection is effective only if you

connect at least one of the bushes to the grounded control

valves through electrically conductive (bare) attachments.
