ELECTRICAL CONNECTIONS
WARNINGS:
The electrical connections must only be completed by a
qualified electrician.
A power supply other than the type specified may
seriously damage the system.
Separate as much as possible the probes and
digital input signal cables from the cables carrying
inductive loads and power cables to avoid possible
electromagnetic disturbance. Never lay power cables
(including the electrical cables) and probe signal cables
in the same conduits. Do not install the probe cables
in the immediate vicinity of power devices (contactors,
circuit breakers or similar).
Reduce the path of the probe and sensor cables as much
as possible, and avoid spiral paths that enclose power
devices. The probes must be connected using shielded
cables (minimum cross-section of each wire: 0.5 mm
2
).
Avoid direct contact with internal electronic components.
Connection errors (and connections other than those
indicated in this manual) may involve danger to the
safety of the users and cause faults on the instruments
and the components connected.
Fit the unit with all the electromechanical safety
devices required to guarantee correct operation and the
complete safety of the user.
