Overview
This article explains the different types of cables used for connecting the Control Unit (CU-4E/CU-4D) with the Gen 5/Gen 6 family of sensors. For the list of all Gen 5/Gen 6 cables, refer to the Cables (CBL-xx-xx-xx) - Spec Sheet .
The Control Units (CU-4) applies to the following models:
- Fixture Mount Control Unit for 0-10V drivers: CU-4E-FMH,
- Nipple Mount External/Internal Control Unit: CU-4E-NME/NMI, for North America only
The Control Units (CU-4D) applies to the following models:
- Fixture Mount Control Unit for DALI drivers: CU-4D-FM, for use in the EU only.
The following sections are categorized based on the type of Gen 5 sensor connected to the Control Unit (CU-4E/CU-4D).
Overview: Gen 5/Gen 6 Sensors Cabling Matrix
The Sensor Cabling Matrix table provides an overview of the cables needed to connect a Gen 5 sensor to the Control Unit. The table is categorized based on the type of Gen 5 sensor and Control Unit model.
The maximum cable length between an Enlighted SU-5 sensor (SU-5E or SU-5S) and a CU-4E/CU-4D control unit can be up to 300' of CAT3 or better (CAT5, 5E, 6E) cable. Multiple cables from different sensors going to different CUs can share the same raceway or cable tray without signal degradation or cross-talk. Maintain the separation of circuits from class 1 wiring per the requirements of the AHJ.
Note: All Enlighted cables are plenum-rated as indicated by the CMP (Communications Multipurpose Plenum), 600 VAC, #24 AWG CAT 3 cables, and UL numbers are indicated on the cable.
Notes:
- All Ruggedized sensors (-xRx) have integrated 20" cable with connector (RJ12 or RJ45). Note the required cable extensions in the table.
- Any Gen 5, 2-wire sensor can be connected to function as a fixtureless sensor. For details, refer to 2-wire Fixtureless Sensors.
- All IoT, Connected Lighting (CL), and Independent Lighting (IL) product codes for Micro sensor (SU-5E), High Bay, Ruggedized sensors (SU-5S) are covered in the appropriate SU-5E/5S sensor column.
