Observe the accident prevention rules of the Employers Liability
Insurance Association.
Observe the safety instructions for the pneumatic actuator used. The
actuator's high actuating power may cause injuries!
Take suitable precautions to ensure that even in case of malfunctions
the positioner's max. admissible operating pressure of 6 bar (90 psi) is
not exceeded. Otherwise, the positioner and/or the actuator may be
damaged.
The positioner must be supplied with instrument air exempt from oil,
water and dust according to DIN/ISO 8573-1, Class 3
- Purity: max. particle size 5 µm, max. particle density 5 mg/m
- Oil content: max. concentration 1 mg/m
- Pressure dew point: maximum value 10 K below operating temp.
Before connecting the air pipes blow them out to remove dust, splinters
and other particles.
Observe the common VDE safety regulations and the accident
prevention rules of the Employers Liability Insurance Association.
Observe the common standards and safety regulations for the
installation and operation of electrical systems.
When connecting the device, observe all electrical specifications in
these operating instructions or in the data sheet.
For the electrical installation of explosion-protected devices, observe all
standards, regulations and directives governing explosion protection
and applicable for the construction and use of explosion-protected
systems, especially the DIN/VDE directives, the directives for explosion
protection (VDE 0165 or EN 60079), and the special requirements and
specifications for your devices (see the following chapter "Explosion
protection" and chapter "Certificates" starting on page 40).
Exclusively power devices with explosion protection via an electrically
isolated circuit with safe extra-low voltage (SELV) in accordance with
EN 60 950.
Power supply
The basic device is bus-powered via the Fieldbus connected to the bus
terminals +(11) and -(12). The option modules have to be supplied
separately.
When connecting a power source for test purposes without
establishing a bus communication (e.g. when executing the Autoadjust
function), a supply voltage between 9.0 V DC and a maximum of
32 V DC can be applied.
