Rev 27.05.2021
Make certain that the cable gland is properly tightened to ensure the conformity to IP65
protection class.
The screwless quick connect spring terminals on the E2407 are suitable for a wide range
of wires with cross-section 0,2...1,5 mm
2
. The recommended wire stripping length is 8...9
mm. Push the spring loaded terminal lever, insert the wire end into the terminal hole and
release the lever.
Use twisted pair cable, e.g. LiYY TP 2×2×0,5 mm2 or CAT 5, to connect the device to the
RS485 network. Use one pair for A and B wires and the second pair for common 0V and
power +U wires. to connect the transmitter to the Fieldbus network.polarity must be
respected when connecting to an external RS485 network.
Overall length of all connections via the RS485 interface should not exceed 1200 m.
Both analog outputs can be independently changed between 4-20 mA and 0-10 V type
using jumpers J1 (OUT1) and J2 (OUT2). By closing pins on a specific jumper the related
output is 0-10 V, with an open jumper the output is 4-20 mA. Power restart is required after
changing the position of the jumpers.
NOTE! The outputs are not galvanically isolated from the external power supply and share
a common 0V. Allowed load resistance limits are stated in the Specifications table. To
power the instrument from an external power source, connect terminals 0V and +U to the
source. If the integrated mains power supply module is used, connect terminals L and N to
the mains.
NOTE! If the instrument is powered from mains, connect to 0V and +U terminals only light
external loads, which consume less than 30 mA in total, as the integrated mains supply
module capacity is limited.
NOTE! Actuator short-circuits should be avoided, to protect the instrument relays use
external fuses or safety switches.
When the detector is fixed and the external devices connected, place the lid back and fix it
with the screws.
