Guidelines
▪ Make sure the length of the earth wire between the fixation point and the
terminal is longer than the length of the power supply wires between the fixation
point and the terminal.
▪ Cut a slit in the rubber bushing where cables enter the switch box.
▪ Attach the cables onto the outer cable jacket and NOT onto the wires.
▪ Do NOT strip the outer cable jacket lower than the fixation point.
▪ Leave sufficient spare cable (± 20 cm additionally) for all cables between the
fixation point inside the switch box and the fixation point on the side of the BS
unit. This spare cable is required to lower the switch box.
