Caution
Caution
The Modul1000 is destructed by aggressive substances.
Avoid contact to bases, acids, solvents and do not expose it to extreme climatic
conditions.
Caution
The Modul1000 may be damaged by improper transport conditions.
Only use this device for detecting helium and hydrogen.
Use a filter in the inlet of the Modul1000 to avoid dirt from getting into the vacuum
system.
Caution
The electronic system of the Modul1000 may be damaged by the wrong supply
voltage.
Check, if the local power supply voltage complies with the required supply voltage
of the device.
Caution
The electronic system of the Modul1000 may be damaged by too high voltages.
The digital inputs are designed for maximum 30 V.
Caution
The electronic system of the Modul1000 may be damaged by too high electric
loads.
The relay outputs should be connected to maximum 60V DC or 25 V AC / 1A at
ohmic load. The semiconductor outputs should only be connected to 30V / 1A.
Caution
The electronic system of the Modul1000 can be destroyed when devices are
connected to the Modul1000 whose electronic circuitry is not safely separated from
the mains.
Only connect devices to the Modul1000 whose connections are safely separated
from the power system.
