wall for example. Adhesive tape can be used if the surface is smooth and
solid, otherwise the special screw and screw anchor supplied.
WARNING: Carefully follow all the connection instructions, if you have
any doubts do NOT make experiments but consult the relevant techni-
cal specifications sheets.
An incorrect connection may cause serious damage to the RC1 receiver.
Power supply
Use terminals 5-6-7 for the main power supply to the RC1 receiver (ground,
phase, neutral), as shown in figure 13.
Motor connection
The single-phase asynchronous motor powered by the electrical mains must
be connected to terminals 1-2-3-4 as shown in figure 13. No. 2 is the "Com-
mon" terminal; blue is normally used in the motor cable; no. 4 is the "earth"
cable (yel low / green). Terminals 1 and 3 correspond to the "Descent" s and
"Ascent" t, respectively. they are usually brown and black in the motor cable.
The electrical phases of the "ascent" and "descent" motor can be inter-
changed as the former causes the motor to rotate in one way, the latter in the
opposite way. The "Ascent" s or "Descent" t direction depends on which
side of the winding tube the motor has been inserted into. If, after memoriza-
tion of the first STX1 transmitter, the direction of rotation of the motor does
not correspond to the command, then invert the connections in Terminals 1
and 3 of the RT3N receiver.
WARNING: do not connect more than one motor per RC1 receiver
unless this is explicitly permitted by the type of motor. If, however, this is
necessary, use special expansion cards to carry out the work.
WARNING: Terminal 7 (Neutral) is directly connected to Terminal 2
(Common) of the motor. Consequently, it is not completely insulated
from the power supply line.
