Their pneumatic connections areoptionallydesignedasaborewith¼NPTorG¼thread.Thecustomaryfittingsformet-al and copper pipes or plastic hoses can be used.Keepthelengthofthelineasshortaspossibletoavoiddelaysincontrolsignaltransmission.

NOTICEThe supply air must be dry and free from oil and dust. The maintenance in-structions for upstream pressure reduc-ing stations must be observed.Blow through all air pipes and hoses thoroughly prior to connecting them.

Thesignalpressureconnectionisfixedwhenthe positioner is directly attached to the Type 3277Actuator.For attachment according to IEC 60534-6(NAMUR),thesignalpressurecanberoutedtoeitherthetoporbottomdiaphragmcham-beroftheactuator,dependingontheactua-

If there are no specifications, calculate as follows:Required supply pressure = Upper benchrangevalue+1bar

Note:The signal pressure at the output (38) of the positioner can be restricted to approx. 2.4 bar by setting P9 param-eter code to ON.

5.2 Electrical connections

DANGER!Risk of electric shock and/or the for-mation of an explosive atmosphere!

− For electrical installation, observe the relevant electrotechnical regu-lations and the accident prevention regulations that apply in the coun-try of use. The following regulation applies to mounting and installation in hazardous areas: EN 60079-14: Explosive atmospheres – Part 14: Electrical installations design, selec-tion and erection. − Avoid electrostatic charging of the plastic housing when mounting and servicing the positioner in hazard-ous areas.

NOTICE − Do not loosen enameled screws in or on the housing. − The maximum permissible values (Ui, Ii, Pi, Li and Ci) specified in the EC-type examination certificate ap-ply when interconnecting intrinsical-ly safe electrical equipment).

NOTICEOnly a current source must be used for the electrical supply. Do not use a volt-age source!

− Connectthesupplyair(Supply9). − Connectthe4to20mAsignal(terminals+11/–12).

Note:After connecting the electrical signal (power supply), the positioner per-forms a calibration of the capacitive keys which takes approx. three sec-onds. During this time, do not touch the key panel. Otherwise, the keys will not work properly. Disconnect and recon-nect the electrical signal to restart the calibration of keys.
