ELECTRICAL INSTALLATION
The MCT 1302 instrument uses for the electrical connection of the 3.81 mm removable screw terminal
blocks. The load cell cable must be shielded and channeled away from power cables to avoid elec-
tromagnetic interference.
The field wiring of the instrument must be suitable for the environment in which it will be used
and must comply with all national regulations.
A switch or disconnector must be included in the electrical system.
The switch must be close to the instrument and easily reachable by the operator.
The switch must be marked as a device to stop the machine.
The switch or circuit breaker used as a disconnecting device must comply with the applicable require-
ments of IEC 60947-1 and IEC 60947-3.
WARNING
Disconnect the power supply to the instrument before making electrical connections.
POWER SUPPLY OF THE INSTRUMENT
The instrument is powered through terminals 25 and 26. The power cable must be routed separately
from other cables.
The electric zero (terminal 26) is connected to the metal case. Connect
the terminal 26, in addition to the GND of the power supply, also
on the ground using the screw near the power terminals.
Supply voltage: 18÷30 Vdc, max 5W
