ATTENTION:

Read the manual carefully before starting to use the control unit. Keep the instructions for future reference.

Do not open the device, touching any internal components can cause electric shock. Contact with 110-240 Volts
AC can be fatal. To reduce the risk of electric shock, do not dismantle the back of the device for any reason. Moreover its
opening would void the warranty. Before connecting the device to the power supply, make sure that all the

connections are correct. Always disconnect the unit from the supply before any cabling modification.

Any intervention on the equipment must be entrusted to a qualified repair engineer

Failure to comply with these instructions can cause damages, fires or electric shock, and possible serious
injuries!

POWER SUPPLY

The T154 series has UNIVERSAL power supply, i.e. it can be supplied by 24 to 240 Vac-Vdc, irrespectively of polarity in Vdc.
Before using it, make sure the power cable is not damaged, kinked or pinched. Do not tamper with the power cable. Never
disconnect the unit by pulling the cable, avoid touching the pins. Do not carry out any connecting/disconnecting with wet
hands. To disconnect the device, do not use objects such as levers. Immediately disconnect the device if you smell burning
or see any smoke: contact technical service.

LIQUIDS
Do not expose the equipment to splashes or drops, do not position it in places with humidity exceeding 90% and never touch
with wet or humid hands during storms. If any liquid penetrates the control unit, disconnect it immediately and contact
technical service.

CLEANING
Disconnect the power cable before cleaning the control unit, use a dry cloth to dust it, without any solvent or detergents, and
compressed air.

OBJECTS
Never insert any objects into the cracks of the control unit. If this happens, disconnect the control unit and
contact an engineer.

USE RESERVED TO QUALIFIED PERSONNEL
The purchased goods are a sophisticated electronic device that is totally unsuitable to be used by non-qualified personnel.
Any intervention must be carried out by a specialist engineer.

ACCESSORIES
The use of non-original accessories or spare parts might damage the unit and endanger users' safety. In the event of faults,
contact technical service.

LOCATION
Install the control unit indoors, in a place protected from water splashes and sun rays. Do not place near heat sources
exceeding the parameters stated in this manual. Position on a stable surface, far from any possible vibrations. Position the
unit as far as possible from any intense magnetic fields.

REPAIRS
Do not open the control unit. For any fault, always use qualified personnel. The opening of the control unit and/or the removal
of the series identifying label entails the automatic forfeiture of the warranty. The Warranty seal is applied to all devices, any
attempt to open the unit would break the seal and cause the consequent automatic forfeiture of the warranty.
