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
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.
