5. INSTALLATION
NOTE. The equipment complies with the 89/366/EEC, 73/23/EEC standards and following
amendments. However, if not properly installed, it may generate a magnetic field and radio
interference. This is why compliance with EMC standards on electromagnetic compatibility
is essential.
5.1 ENVIRONMENTAL REQUIREMENTS
The environment in which the instrument is installed must satisfy the following features:
no vibrations•
indoor area•
operating temperature between -15°C and +60°C (+5°F and +140°F)•
storage temperature between -25°C and +75°C (-13°F and +167°F)•
max humidity 80% (no condensation)•
altitude up to 2000m•
NOTE. The instrument must not be exposed to sun rays.
5.2 MOUNTING
Fastening to DIN EN 50022-rail is provided for the instrument. To mount
it on the DIN-rail, you simply need to use a screw driver as a lever on
the plastic hook on the base of the instrument itself.
This operation will allow the instrument to fit on the rail.
6. SAFETY MEASURES
DANGER!
This warning means that a voltage exceeding 1kV (even if for short periods) may be
present on the terminals.
WARNING!
Electrical instrument connections must be carried out only by skilled technicians who
are aware of the risks involved to the presence of voltage. Before connecting, check the
following:
the conductor wires are not powered1.
the instrument is connected according to the appropriate diagram (see section 7.3)2.
the power supply corresponds to the values on the instrument label3.
the instrument has been installed in a vibration-free and a suitable temperature environment (see 4.
section 5.1)
the terminals are no longer accessible after being connected5.
the wiring is carried out in accordance with the standards in force in the country where the instrument 6.
is to be installed
an isolator and an over-current device (eg. fuse) are installed between the instrument power supply 7.
and the electrical system
the connections are made respecting the polarities. 8. Important: L1 of the voltage input = L1 of the
amperometric input
input and output polarities are respected when using current/voltage transformers9.
the connectors are fixed in such a way that they cannot be accidentally disconnected10.
