1.Description
Power supplier PS440-A/xxx accepts various voltages on the input, as indicated
in the following table:
PS440/230Vac: 230 Vac input voltage
PS440/115Vac: 115 Vac input voltage
PS440/24Vac: 24 Vac input voltage
Power supplier PS440/xxx provides the necessary voltages and interfacing
signals for operating weighing terminal D440IS, by means of intrinsic safety
circuits.
The power supplier is suitable for operation in areas where there is a risk of
explosion. It is made in compliance with directive ATEX 2014/34/UE and
according to standards EN60079-0, EN60079-7, EN60079-11, EN60079-18,
EN60079-26, EN60079-31, with the following protection modes:
 GAS: Ex e mb [ia Ga], T4 Gb
 DUST: Ex tb mb [ia Da] IIIC T100°C, T135°C Db
 Ambient operating temperature
Tamb (-20°C ÷ +40°C) → T5/T100°C
 Tamb (-20°C ÷ +55°C)→ T4/T135°C
The PS440-A/xxx comes in an IP66 protection degree polyester case with Ex-
e/Ex-t cable clamp (object of separate certification) for cable entry.

5. Safety instructions for installation in hazardous areas
Power supplier PS440/xxx (note 1) must be installed and serviced in compliance
with the installation and maintenance instructions for sites classified against the
risk of explosion, owing to the presence of gas and dust (example: EN 60079-
14, EN 60079-17 or other national norms/standards).
Warning: carefully read the technical specifications enclosed with both power
supplier PS440-A/xxx (note 1) and terminal D440IS.
Plate warning:
“DO NOT OPEN WHEN UNDER POWER”
Note 1:
Power supplier PS440-A/xxx is supplied for different powering voltage
ratings. The xxx suffix indicates the value and type of power input.
