VM100

1.1.1 Reed contact - Switching of inductive or capacitive loads

CAUTION! Destruction or damage of reed contact!
Take notice of the max. contact loads mentioned on the specification plate!
The max. contact loads mentioned on the type plate (switching voltage, switching current and
switching capacity) refer to pure ohmic loads and may not be exceeded under any circum-
stances.
High voltage and current peaks can occur, particularly when switching inductive or capacitive
loads (e.g. relay coil, capacitors). Even if the overload is brief, this can destroy (welding the
contacts) or damage (reduced lifespan) the reed contact.
 Only use protection methods which be appropriate and checked.
Protection method when electrical connection of reed contacts:
The following protective circuits are basically possible: current limiting resistors, RC cir-
cuits, freewheeling diodes, suppression diodes, varistors or a combination of these.
Please verify the effectiveness of the chosen protection method in accordance with the
specific loads involved.

1.2 Exclusion of liability

We accept no liability for any damage or malfunctions resulting from incorrect installation, in-
appropriate use of the device or failure to follow the instructions in this operating manual.
