NOTES
ON ELECTRIC
SAFETY AND
ELECTROMAGNETIC
COMPATIBILITY
Please, read carefully these instructions before proceeding with
the installation of the controller.
Class II instrument, for indoor use only.
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 n° 89/336/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.
Reapirs: this 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 pro-
vides technical 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.

1.1 GENERAL DESCRIPTION
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

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.
2.2 SUGGESTED WIRES ROUTING B
Conduit for supply and output cables

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 regulations, 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 PTC protected. In case of failure it is suggested to return
the instrument to the manufacturer for repair.
5]
To protect the contacts of the relay outputs (OP1 and OP2) use a
2 A
~ T (220 V ~ ) or a 4 A ~ T (120 V ~ ) .
6] Relay contacts are already protected with varistors.
Only in case of 24 V~inductive loads, use model A51-065-30D7
varistors (on request).

2.3.2 PV CONTROL INPUT B
A For L-J-K-S-T thermocouple type
• Connect the wires with the
polarity as shown.
• Use always compensation cable
of the correct type for the ther-
mocouple used.
• The shield, if present, must be
connected to a proper earth.
B For Pt100 resistance
thermometer
• If a 3 wires system is used, use
always cables of the same sec-
tion (1mm2min.) (line 20 Ω/lead
maximum resistance).
• When using a 2 wires system, use
always cables of the same section
(1,5mm2min.) and put a jumper
between terminals 5 and 6.
C For ∆T (2x RTD Pt100) Special

the controller and the sensor
is 15 m using a cable of 1.5
