United Automation Infresco T 6.0kW User & Installation Manual

INTRODUCTION

SAFETY FIRST
Please read these instructions before installing and operating this product.
Infresco-T 6kW
The Infresco-T 6kW is part of a family of controllers designed to provide energy saving
when used with Quartz Infrared Halogen Lamps or other Heating and Lighting Products.
The 'T' model switches the lamps on for a pre-determined time period of between 1 and
30 minutes. Designed with ease of wiring in mind, this unit is ideal for controlling up to
four 1.5kW lamps through the use of two additional cable entry points.
The microcontroller-based unit incorporates zero-voltage switching and a soft-start
function to eliminate the lamps' initial high inrush current – potentially increasing lamp life
by as much as 30% and reducing the stress on the mains supply.
Heating lamps, Garden lighting
Installation is simple and once installed is relatively maintenance free.

Installation

The Infresco-T 6kW unit should be positioned with the cable glands facing down and
securely fixed via the four mounting holes accessible from the front of the unit or by the
alternative rear mounting holes underneath the PCB. For the latter option, remove the
four screws securing the PCB and carefully remove the PCB to allow access to the rear
mounting holes. Cover any holes used with caps supplied with the unit.

Wiring

Warning! Ensure the mains supply has been isolated before wiring this unit.
The unit is fitted with three cable glands. Only one cable should be fitted per gland to
maintain the unit's IP rating. Two additional cable glands can be fitted to allow the
connection of up to four lamps. See Figure 2.
The mains supply connects to the terminal block marked 'LINE'. Connect the supply LIVE
to the 'L' terminal, NEUTRAL to the 'N' terminal and EARTH to the 'E' terminal.
The lamps connect to the terminal block marked 'LOAD'. Connect the load LIVE to the 'L'
terminal, NEUTRAL to the 'N' terminal and EARTH to the 'E' terminal.
connections are paired to allow the connection of several lamps.
Important: Ensure all earth wires are connected to maintain earth continuity to
the lamp fittings.
Check all wiring - particularly the line and load connections and make sure the cable glands
