NOTES
ON ELECTRIC
SAFETY AND
ELECTROMAGNETIC
COMPATIBILITY.
Please, read carefully these instructions before proceeding with
the installation of the controller.
Class II instrument, real panel mounting.
This controller has been designed with compliance to:
Regulations on electrical apparatus (appliance, systems and installa-
tions) according to the European Community directive 73/23 CEE amend-
ed by the European Comunity directive 93/68 CEE and the Regulations
on the essential protection requirements in electrical apparatus EN 61010-
1 (IEC 1010 - 1) : 90 +A1:92 + A2:95.
Regulations on Electromagnetic Compatibility according to the
European Community directive n089/336/CEE, amended by the European
Community directive n° 92/31/CEE and the following regulations:
Regulations on RF emissions
EN50081 - 1 residential environments
EN50081 - 2 industrial environments
Regulation on RF immunity
EN500082-2 industrial equipment and system
Itisimportanttounderstandthatit’sresponsibility of the installer to ensure
the compliance of the regulations on safety requirements and EMC.
The device has no user serviceable parts and requires special equipment
and specialised engineers. Therefore, a repair can be hardly carried on
directly by the user. For this purpose, the manufacturer provides techni-
cal assistance and the repair service for its Customers.
Please, contact your nearest Agent for further information.
All the information and warnings about safety and electromagnetic
compatibility are marked with the Bsign, at the side of the note.

PRECAUTIONS B
Despite the fact that the instrument
has been designed to work in an
harsh and noisy environmental
(level IV of the industrial standard
IEC 801-4), it is recommended to
follow the following suggestions.
A
All the wiring must comply with the
local regulations.
The supply wiring should be rout-
ed away from the power cables.
Avoid to use electromagnetic con-
tactors, power Relays and high
power motors nearby.
Avoid power units nearby, espe-
cially if controlled in phase angle
Keep the low level sensor input
wires away from the power lines
and the output cables.
If this is not achievable, use shield-
ed cables on the sensor input, with
the shield connected to earth.

Notes:
1] Make sure that the power supply
voltage is the same indicated on
the instrument.
2] Switch on the power supply only
after that all the electrical con-
nections have been completed.
3] In accordance with the safety reg-
ulations, the power supply switch
shall bring the identification of the
relevant instrument. The power
supply switch shall be easily
accessible from the operator.
4] The instrument is is PTC pro-
tected. In case of failure it is sug-
gested to return the instrument to
the manufacturer for repair.
5] To protect the instrument internal
circuits use:
- 2 A~T fuses for Relay outputs
- 1 A~T fuses for Triac outputs
6] Relay contacts are already pro-
tected with varistors.
Only in case of 24 V ~induc-
tive loads, use model A51-065-
30D7 varistors (on request)
