POWER CONNECTIONS
Low voltage Plug in transformer.
Connect 512/16volt or 624/24volt AC from transformer to 16/24V AC connectors on controller card.
DO NOT CONNECT 220V DIRECTLY TO PCB
Low voltage (OBT) (25 VA) transformer – 220V at gate. (DTS512 has a 500m/Amp fuse)
Connect 220V AC to input side of 512/16volt or 624/24volt AC transformer (black & brown wires), or to
NEL (Neutral/Earth/ Live) connector on side of transformer, then connect the output wires (red) to
16/24V AC connectors on controller card.
DO NOT CONNECT 220V DIRECTLY TO PCB
WHEN 220V IS USED AT GATE MOTOR, A SEPARATE DOUBLE POLE ISOLATOR MUST
BE FITTED WITHIN 1METER FROM THE MOTOR.
