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/EEC amend-
ed by the European Comunity directive 93/68/EEC and the Regulations
on the essential protection requirements in electrical apparatus EN61010-
1 : 93 + A2:95.
Regulations on Electromagnetic Compatibility according to the
European Community directive n089/336/EEC, amended by the European
Community directive n° 92/31/EEC, 93/68/EEC, 98/13/EEC
and the following regulations:
Regulations on RF emissions
EN61000-6-3 : 2001 residential environments
EN61000-6-4 : 2001 industrial environments
Regulation on RF immunity
EN61000-6-2 : 2001 industrial equipment and system
It is important to understand that it’s responsibility 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.

1INSTALLATION
Installation must only be carried
out by qualified personnel.
Before proceeding with the instal-
lation of this controller, follow the
instructions illustrated in this man-
ual and, particularly the installation
precautions marked with the B
symbol, related to the European
Community directive on electrical
protection and electromagnetic
compatibility.
B
To prevent hands or metal touch-
ing parts that may be electrically
live, the controllers must be
installed in an enclosure and/or

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 connec-
tions 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 acces-
sible from the operator.
4] The instrument is is PTC protect-
ed. In case of failure it is suggest-
ed to return the instrument to the
manufacturer for repair.
5] To protect the instrument internal
circuits use:
- 2AT fuse for 220Vac relay outputs;
- 4 AT fuse for 110Vac relay outputs;
- 1 AacT fuse for Triac outputs.
6] Relay contacts are already pro-
tected with varistors.
Only in case of 24 Vac inductive
loads, use model A51-065-30D7
varistors (on request)

• The shield, if present, must be
connected to a proper earth.
B For Pt100 resistance

• If a 3 wires system is used, use
always cables of the same diam-
eter (1mm2min.) (line 20 Ω/lead
maximum resistance)
• When using a 2 wires system, use
always cables of the same diam-
eter (1.5mm2min.) and put a
jumper between terminals 5 and 6
C For ∆T (2x RTD Pt100) Special
A When the distance between
the controller and the sensor is
15 m. using a cable of 1.5 mm2
diameter, produces an error on
