1. WARNINGS
1.1 General 

information

All PASO equipment is built according to the strictest international safety standards and complies with European Community requisites. 

In order to use the equipment correctly and effectively, it is important to be aware of all its features by reading these instructions and 
in particular the notes on safety carefully.

 While the equipment is working, it is necessary to ensure adequate ventilation. 

Avoid closing the equipment inside a cabinet without ventilation and take care not to obstruct the ventilation slits. Also avoid keeping the equipment 
near a source of heat (radiator, heating systems and so on). 
Before switching on the equipment, make sure that all the inputs and outputs are correctly connected.

1.2  Power supply and earthing

The equipment has provisions for operation with a mains voltage of 230 V ± 10% 50/60 Hz. As an alternative, the equipment can be used with a 
constant voltage of 24V

DC

.

1.3 Safety 

notes

Any work inside the equipment, such as selecting some of the modes of operation or applying accessories may only be carried out by specialised 
personnel. 

On removing the cover, parts entailing a danger of electric shocks will be made accessible

. Always make sure that the mains 

cable of the power-supply module is disconnected before removing the panels. If any liquid is accidentally spilt on the equipment, disconnect 
the mains cable immediately and contact the nearest PASO Service Centre. The equipment is supplied with its own power-supply cable with an 
earth wire. The relevant terminal on the mains plug must never be removed, under any circumstances. Make sure that the power outlet has a 
connection to earth in accordance with the law. 
The frame ground connection     (

8

) can be used to connect other equipment for the sole purpose of shielding low-level signals. 

This socket must never be used for the safety connection of the frame to earth

.

IMPORTANT! The terminals marked with the symbol   are active and dangerous. The external connections toward these terminals 
MUST be carried out by specialized personnel only.

Note: 

Before using the equipment, make yourself aware of all characteristics by reading carefully the instructions included in the printed manual 

or on the CD, paying particular attention to the safety notes.

Note: 

PASO S.p.A will not accept any liability for damage to property and/or persons arising out of incorrect use of the equipment or of
