Det-Tronics Open Path Eclipse Instructions Manual page 43

INSTALLATION AND WIRING
The Eagle Quantum Premier (EQP) version of the Model OPECL Open Path Eclipse uses the identical installation
procedure, device location guidelines, and power supply requirements as described in the "Installation" section of
this manual. Refer to the EQP version wiring diagram for specific wiring termination guidance.
An important difference in EQP applications is that LON network cabling will be routed both in and out from the the
EQP OPECL receiver enclosure, so this requirement should be anticipated and planned for during installation.
Note that only the receiver is connected to the LON network. The transmitter is not connected to the LON and
requires wiring for operating power only.
Det‑Tronics recommends the use of shielded cable (required by ATEX) to prevent external electromagnetic
interference from affecting field devices.
For best fault isolation performance, the maximum LON wiring length should not exceed 1600 feet (500 meters).
Be sure that selected cable meets all job specifications. The use of other cable types can degrade system
operation. If necessary, consult factory for further suggested cable types.
