Signal Pressure (Output); Electrical Connections - Samson 3730 Series Mounting And Operating Instructions

5.15.4 Signal pressure (output)

The signal pressure at the output (38) of the
positioner can be restricted to 1.4 bar,
2.4 bar or 3.7 bar in Code 16.
The limitation is not activated [No] by de-
fault.

5.16 Electrical connections

For electrical installation, observe the rele-
vant electrotechnical regulations and the ac-
cident prevention regulations that apply in
the country of use. In Germany, these are
the VDE regulations and the accident pre-
vention regulations of the employers' liability
insurance.
DANGER
!
Risk of fatal injury due to the formation of
an explosive atmosphere.
The following regulations apply to installation
in hazardous areas: EN 60079-14
(VDE 0165, Part 1) Explosive Atmospheres –
Electrical Installations Design, Selection and
Erection.
EB 8384-5 EN
WARNING
!
Incorrect electrical connection will render the
explosion protection unsafe.
− Adhere to the terminal assignment.
− Do not undo the enameled screws in or on
the housing.
− Do not exceed the maximum permissible
values specified in the EC type examina-
tion certificates when interconnecting in-

Selecting cables and wires
Observe clause 12 of EN 60079-14: 2008
(VDE 0165, Part 1) for installation of the in-
trinsically safe circuits.
Clause 12.2.2.7 applies when running multi-
core cables and wires with more than one
intrinsically safe circuit.
The radial thickness of the insulation of a
conductor for common insulating materials
(e.g. polyethylene) must not be smaller than
0.2 mm. The diameter of an individual wire
in a fine-stranded conductor must not be
smaller than 0.1 mm. Protect the conductor
ends against splicing, e.g. by using wire-end
ferrules. When two separate cables or wires
are used for connection, an additional cable
gland can be installed. Seal cable entries left
unused with plugs. Fit equipment used in
ambient temperatures below –20 °C with
metal cable entries.
