CONNECTION TO ELECTRONIC CONTROL UNIT
Ü
Always disconnect the electrical power supply before
carrying out any operations on the control unit (connections,
programming, maintenance).
Warning: On disconnecting connector J6, high voltages
may be present on the capacitor output.
Observe points 10, 11, 12, 13 and 14 in the GENERAL SAFETY
INSTRUCTIONS.
Lay the cables in the conduits as shown in Fig. 3 and make the
electrical connections to the chosen accessories.
Always route the power supply cables separately from the
control and safety cables (keyswitch, receiver, photocells,
etc.). Use separate conduits to avoid any interference.
