Conduit Requirements for MBD wiring
To prevent interference during the operation, there should be a separate conduit for each
signal line, control line and AC power line. Especially ANALOG signal line of MBS must be
in separate conduit from other equipments or AC power lines or control lines for other
equipments. Otherwise, MBS operation will be interfered.
If separate conduits cannot be supplied, keep enough distance (generally 300mm or more)
between different wirings. It is effective to prevent interference.
