Installation instructions (continued)
WARNING: before opening the upper cover shut down the power
supply voltage.
To remove the upper cover “A” untighten the screws “D” and make
sure to avoid collisions with the internal electrical parts. Insert the
power supply cables inside the lower enclosure entries “E”, tighten
by the user. The terminal block “F” is composed by two parts, one of
which removable. To simplify the procedure, it is possible to remove
the removable part, wiring it and insert it once the wiring is done.
Proceed to the cable connections in the appropriate terminal block
“F” following the wiring diagram (paragraph 6.1).
WARNING: please pay attention during the wiring and setting
phases of the electromechanical limit switches, in order to avoid
fluids or other substance from getting on or around any electronic
components. Moreover, before assembling the upper cover please
make sure that the o-ring is seated in the proper groove and there
are no impediments that could compromised the enclosure sealing.
6.1 Electrical connection
The wiring diagram, which should be followed for proper wiring of
the actuators, is shown in paragraph 10.0 and it can be found also
on the label inside the upper cover. Please follow the maximum
allowed electrical rating values. The terminal block “F” in the 100-
240Vac is shown in Fig. 3, 12Vac/dc and 24Vac/dc in Fig. 2. The
cables through the connector must be of the proper size.
•
The signal cable of “closing (clockwise rotation)” (positive
12Vdc / +24Vdc or phase 12Vac / 24Vac / 100-240Vac)
must be connected to the terminal “1” of the terminal-block “F”;
•
The signal cable of “opening (counter-clockwise rotation)” (pos-
itive 12Vdc / +24Vdc or phase 12Vac / 24Vac/ 100-
240Vac) must be connected to the terminal “3” of the termi-
nal-block “F”;
•
The signal cable “common” (0V / neutral) must be connected to
the terminal “2” of the terminal-block “F”;
•
The grounding cable must be connected to the properly sig-
naled terminal.
•
In addition to the 3-points control mode, the 2-points control
mode is also available.
WARNING: the ground wiring system is mandatory.
