VITM4-2CH-2S
Vitesse Modular 4 - 2 Ch / 2 supply 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-2S is a two channel, non-dimming distribution box for use in applications that require two independ-
ent supplies for switching lighting or lighting and ventilation circuits. For example this product is ideal for installations
that have essential and non-essential supplies for lighting circuits and require common switching using presence detectors. This product provides connections for separate Live, Neutral and Permanent Live inputs.

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

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