Installation
3.1
Mounting position
Rail-mounting unit
Snap the device onto the top-hat rail (see
Rail-mounting unit on page 19).
Optionally, mount it to a wall using the two
Ø 5.5 mm holes.
The devices can also be mounted to a supply
air manifold using the corresponding acces-
sories (see section 11).
Field unit
Mount it using the bracket (1400-7432). See
Field unit on page 20.
3.2
Electrical connection
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.
Adhere to the terminal assignment specified
in the certificate. Switching the assignment of
the electrical terminals may cause the explo-
sion protection to become ineffective.
Î
Connect the wires for the input signal to
the (+) and (–) terminals. The terminals
are designed for wires with 0.2 to
2.5 mm² (see section 9). No additional
voltage supply is required.
