2 Installation, connecting-up
The board is snapped onto a mounting rail. The components must be wired-up by others.
The board provides no protection against direct contact. Protection against direct contact is ensured by
mounting it in an enclosure or in a cabinet.
Screened cables must be used to prevent EMC disturbance. Screens must be connected at X80 and X81.
Perfect functioning of the board cannot be guaranteed if the permissible cable lengths are exceeded (refer to
Figs. 2, 3 and 4). If longer cable lengths are required, please contact your tachometer manufacturer or supplier.
Power- and control cables must be separately routed.
