CDH4U5
4-Channel Programmable
Intelligent Lighting Control Module
Installation and Commissioning Instructions
Introduction
The CDH4U5 is an intelligent LCM providing connections for multiple
luminaires*, up to 5 presence detectors and up to 5 SELV inputs. The product
simplifies installation whilst providing an intelligent lighting control system.
Provision is made for 4 volt-free power outputs rated for 415V isolation.
Additionally, the unit features a switched output for Maintained Live to allow
initiation of Emergency Lighting Test. The CDH4U5 has the ability to operate
from dual supplies with the capability to modify its operating behaviour when
failure is detected on one of the supplies. This feature is described in greater
detail in application note AN4027.
*Note: Refer to Technical Data section to find out maximum allowable number
of luminaires.
Electrical Connections
The connections to this equipment should be made only by a suitably
qualified person and in accordance with the current wiring regulations.
A means of disconnection must be incorporated in the fixed mains
wiring to this box in accordance with the current wiring regulations.
All the connections should be routed ensuring adequate strain relief on the
cable before termination to the unit’s pluggable connectors.

Variants of the CDH4U5 are provided to control DSI, DALI and 1-10V ballasts. (See Part Numbers section for more details.)
Note: Dimming ballast types CANNOT BE MIXED on a single CDH4U5.
The CDH4U5 is equipped with 4 two-wire pluggable terminals for dimming outputs, 2 three-wire and 2 two-wire pluggable terminals for volt-free outputs.
The CDH4U5 has provision to connect more than one supply from different phases in three different scenarios: a) Single Supply, b) Essential and non-essential
supplies and c) Two supplies equally likely to drop out .
