04.1 Warnings for the electrician
04.2 Power supply
The supply voltage must be applied to the BROWN (phase) and BLUE (neutral) wires. Always connect the YELLOW-GREEN wire to the earthing system. The motor's technical
specifications are shown on the label affixed to the motor tube.
04.3 Command buttons
The command buttons are optional. If used, the command buttons must be applied to the BLACK and GRAY wires and must close on the BROWN wire (phase). You must use buttons
with spring return (“man present” type), do not use switches with maintained position. Multiple command buttons can be connected via a parallel connection. The command buttons are
subjected to the mains voltage and, therefore, must be adequately insulated and protected. If the command buttons are not used, insulate the gray and black wires.
04.4 Motor connection to home automation control units
There are different types of home automation control units. Some home automation control units allow programming the closing time of the output contacts, while others do not allow it;
some home automation control units measure the current absorption of the devices applied to the output contacts, while others do not; some home automation control units work with
proprietary protocols, while others work with “standard” protocols (for example KNX, MODBUS, etc...). Given the range of features of different home automation control units available
on the market, the motor's Manufacturer cannot know in advance whether the motor is compatible with the home automation control unit installed. The command outputs of the home
automation control unit must be connected to the push-button inputs of the motor (GRAY and BLACK wires), replacing the manual command buttons. Consequently, the home
automation control unit must comply with the operating rules of the command buttons, keeping into account whether the latter function in PULSE (factory setting) or in MAN PRESENT
mode (see section 12 “Button logic”).
Rules for the home automation control unit to comply with to control motors with PULSE-operated buttons.
a) The home automation control unit MUST NOT measure the current absorbed by the button inputs of the motor (which absorb currents lower than 1 mA).
b) The home automation control unit must be connected to the motor as shown in the diagram, replacing the command buttons with the command outputs of the home automation
control unit.
c) To operate the motor, the home automation control unit must close the contact (up or down) for more than 0.5 seconds (typically a 1 second pulse is used).
d) When the contacts are open, the home automation control unit must close a contact (up or down) for less than 0.5 seconds to stop the motor (typically a pulse of 0.2 seconds is
used).
Rules for the home automation control unit to comply with to control the motors with MAN PRESENT-operated push buttons.
a) The home automation control unit MUST NOT measure the current absorbed by the button inputs of the motor (which absorb currents lower than 1 mA).
b) The home automation control unit must be connected to the motor as shown in the diagram, replacing the command buttons with the command outputs of the home automation
control unit.
c) To allow the completion of the entire opening/closing manoeuvre, the home automation control unit must be able to close the up/down contact for the time necessary for the motor to
perform the complete opening/closing manoeuvre.
d) To stop the motor, the home automation control unit must be able to re-open the up/down contacts at any time.
At the time of printing of this document, no particular problems concerning the connection between STAFER SPA products and home automation control units are known (if the above
rules are complied with). In any case, STAFER shall not be liable in the event of lack of compatibility (even partial) with any home automation control unit. If the home automation control
unit uses KNX or similar protocols, contact the home automation system supplier to discuss the rules listed above. It is likely that the home automation control unit manufacturer can
provide adequate interfaces to connect the motor to the home automation control unit. For additional information, please contact your dealer.

Make all connections with the power supply disconnected.
●
Check that the power line does not feed on electrical circuits to be used for lighting.
●
The power line must be equipped with
a magneto thermal or differential circuit breaker. A category III over voltage disconnection device must be fitted on the power supply line, i.e. at a distance of at least 3.5 mm between the
contacts.
●
The section of the connecting cables must be proportionate to their length and to the power load absorption, and, in any case, not less than 1.5 mm.
●
The product does not
provide for any protection against overloads or short circuits. Provide adequate protection for the load on the power supply line, for example a fuse with a maximum value of 3.15 A.
●
Command buttons are connected to the main voltage, so they must be properly insulated and protected.
