INSTALLATION OF THE CONTROL BOX
The CB11 control board was designed for installation in a special, waterproof box (203391). Before fitting, measure the required distances and
determine the correct holes. Use a screwdriver to force the plastic out of the holes. Insert threaded cable connections with strain relief, hold the
box against the surface on which it is to be mounted. Insert screws through the mounting holes in the rear panel and tighten. The motor control
unit is a highly modern electronic unit controlled by a microprocessor. It has all wiring facilities and functions required for safe operation. Moisture and
water will destroy the control board. Make sure under all circumstances that water, moisture or storage moisture cannot penetrate the control board.
Make sure that all openings and cable entries are sealed watertight. The control box with the motor control unit is mounted with the cable entries facing
down. It must not be permanently exposed to direct sunlight. The electronics can be used for the precise adjustment of the push-pull torque. The gate
can be held by hand if the fitting/setting is correct. During operation, the gate can be stopped at all times via remote control, push-button or key-
operated switch. The gate wing requires a firm stop for the "OPEN" and "CLOSED" positions, because the gate drives have no limit switch.

CURRENT DISTRIBUTION
The cable coming from the drive arm must be inserted into a commercial, waterproof distribution box. A firm cable connection can then be
established from the distribution box to the control board. It is frequently possible to lead the drive, that is fixed directly next to the control board,
directly into the box. Never lay distribution boxes under the ground.
The following minimum cable cross-sections should be used:
• 100-230 volts 1.5 mm² or more more
• 0-24 volts 0.5 mm² or more more
Tips: Bell wires often cause problems when used, because they lose too much voltage if lines are long. Disconnect the cables in the cable
trunkings i.e. the motor cable and the cable for the photocell, in particular for key-operated switches and start buttons (coming from the house),
otherwise malfunctions are possible if lines are long.
