4. Installation, operation and maintenance
4.1 Installation and commissioning
4.1.1 General
After mounting and correct connection, switch on the power
supply.
During the installation of transmitters in environment with
higher level of interference, protection of transmitters
against interference and induced overvoltage must be
ensured. According to the standard engineering practice,
it is recommended to separate signal and power wires into
separate gutters and use shielded signal cables with twisted
wires. In case of outdoor wires, it is necessary to solve the
overvoltage protection of the transmitter as a part of overall
solution of protecting system from the effects of atmospheric
electricity.
4.1.2 Special conditions for use of intrinsically safe
version (code EI1)
II (1) G [Ex ia Ga] IIC
II (1) D [Ex ia Da] IIIC
The transmitter P5335 for installation for DIN rail may
not be installed in any explosion hazard environment.
This restriction also applies to version P5335 Lxx EI1.
Only input and output wires of the version P5335 Lxx EI1 may
lead to explosion hazard environment. The transmitter input
and output may be connected only to suitable associated
apparatus or to simple apparatus complying with the standard
EN 60079-14 when respecting the restricting conditions. When
installing a transmitter, it is necessary to separate terminals
of intrinsically safe circuits by air gaps at least 50 mm from
terminals of the circuits that are not intrinsically safe (see EN
60079-11). In case of a double-channel version P5335 L2x EI1
both channels shall be included in intrinsically safe circuits.
