SAFETY REQUIREMENTS

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 a voltage over 50
Volts 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 work on the equipment must be entrusted to a qualified engineer.

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

POWER SUPPLY

The MM453 series control unit 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, knotted 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 work must be carried out by a specialist engineer.

ACCESSORIES

The use of non-original accessories or spare parts can 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.
