Aurora HA-S105 Dimmable with Resistive and Inductive Dimmers Instruction Manual

IMPORTANT NOTE TO THE INSTALLER

These instructions contain important information. Please ensure that a copy is left with the user/maintenance engineer.

WARNING

This product should be installed by a qualified electrician in accordance with these instructions and the latest edition of the I.E.E. Wiring Regulations (BS 7671) and other relevant regulations (e.g Building. Fire etc). For use with 12V tungsten halogen lamps in Class III low voltage luminaires only. Isolate from the mains supply before installation or maintenance.

INSTALLATION INSTRUCTIONS

The transformers feature loop-in, loop-out primary wiring terminals and an Integrated Earth Terminal to allow Earth continuity to be maintained in the primary wiring circuit. The mains supply should be connected to the Primary Input terminals as follows:
Black/Blue – Neutral (terminals marked N)
Red/Brown – Live (terminals marked L)
Green/Yellow – Earth (terminal marked No pan of the secondary (SELV) circuit should be earthed. (see diagram overleaf).

The transformer should be sited in a well ventilated position. Do not enclose or cover the transformer with thermal insulating materials. The ambient temperature during operation must not exceed the to °C rating of the transformer. Keep the transformer away from direct sources of heat such as low voltage lamps. (see Figure 1). Do not fit the transformer above the luminary (see Figure 2).

Fig.1- Correct Installation

Fig.2- Incorrect Installation

Note: the transformer maybe used in the same lighting circuit as inductive loads (fluorescent lamps, ventilating fans etc.) The transformer is protected against mains surges of up to 1.0kW (in accordance with EN61547)

The output leads must not exceed 2m in length.

Ensure that the wattage of the lamps does not exceed the rating of the transformer.

Do not allow the input and output wiring to cross (see Figure 3).

Fig.3- Do Not Input and output Wiring

Replace failed lamps immediately.

FAULT FINDING

Electronic transformers give little or no output unless connected to a load of the correct rating. To measure output voltage use a true r.m.s. A.C. voltmeter with a bandwidth >30 Khz Do not use a Megger or similar insulation resistance tester on circuits with electronic transformers connected as permanent damage to the transformers may result. Disconnect the transformers before testing.

DIMMING

This transformer may be dimmed with most types of standard resistive and inductive dimmer switches. Install the dimmer switch on the primary (mains) side of the transformer. A slight buzzing noise is normal with some types of dimmer switch.
The dimmer should be loaded to at least 75% of its maximum capacity.
(refer to the dimmer manufacturers’ instructions).

• The 105VA transformer requires a minimum load of 35-Watts for normal operation. For dimming applications a minimum load of 50-Watts is required.
• The 150VA transformer requires a minimum load of 50-Watts for normal operation. For dimming applications a minimum load of 75-Watts is required.
• The 210VA transformer requires a minimum load of 100-Watts for normal operation. For dimming applications a minimum load of 100-Watts is required.

Installation with Dimmer Switch

RADIO INTERFERENCE

In common with other high frequency convertors this product may cause radio interference. Under certain circumstances break through may be experienced on the medium and long wave radio bands. Please note that this transformer is suppressed to all relevant EMC standards.

INPUT TERMINALS

Dual Live & Neutral terminals allow loop-in, loop-out wiring between transformers. Integrated Earth Terminal allows Earth continuity in the primary wiring circuit. (HA-S105, HA-S150 and HA-S210)

OUTPUT TERMINALS

Each pair of output terminals may be connected to a maximum capacity of 105WNA with a combined capacity not to exceed the WNA rating of the transformer itself. Use cable type HO3VV-F or type as specified in the relevant wiring/building regulations or national standards.
Ensure that the cable current rating is adequate for the load connected.

THERMAL PROTECTION

The HA-S105 transformer features a thermal fuse and will shut down in the event of overheating.
The HA-S150 and HA-S210 transformers feature an auto-reset thermal switch and will shut down in the event of overheating and re-start when the temperature returns to normal.
