VITM4-2CH
Vitesse Modular 4 - 2 Channel Switching Modules
Overview
The Vitesse modular system is a cost effective method of providing power and control for lighting installations in in-
dustrial, commercial and retail buildings. The system is designed for ease of installation: mains input is connected
using the spacious wiring compartment; control inputs and outputs are pluggable using industry standard connectors.
The modular approach allows for between 4 and 16 luminaires to be connected.
The VITM4-2CH is a two channel, non-dimming distribution box for use in applications that require two independently
switched lighting circuits, or lighting and ventilation circuits. For example this product is ideal for connection to a 2
channel presence detector for separate window row switching. It has two live inputs, a common neutral and two
switch inputs.

Switched live turns the lights on and off
Use the cable clamps to secure the wiring or use cable glands (not
supplied). The clamps can be split, and flipped over to clamp
different cable diameters.
Replace wiring compartment cover.
Plug in the luminaires ensuring that the connector latches to the box.

Connecting a detector
CH1 and CH2 plugs are coded.
Ensure that the plugs are
inserted correctly and do not
apply excessive force
Detector lead needs to be ordered separately
from the detector. Order code VITM4-L3-2CH.
Where two detectors connect to a single box a
dual lead is available VITM4-LD3-2CH.
