CAUTION!
If the current consumption for the connected detector exceeds 20 mA, it can lead to the
malfunction of or damage to the MPA.
You should restrict the maximum detector current consumption to 20 mA to avoid damaging
the MPA.
NOTICE!
The cable length between the detector and the MPA must not exceed 3 m when connected by
an unshielded cable.
