Assembly recommendation
In the environments of unknown levels of interruptions it is recommended to use the following
means preventing against possible interruptions of the device operation:
•
Ground or zero the metal rails on which instruments are mounted.
•
Do not power the device from the same lines as high power devices without appropriate
network filters.
•
Apply power supply, sensor and signal cables screening while screen grounding should be
connected only on one side as close to the device as possible.
•
Use communication cables (USB) equipped with filters in the form of ferrite beads.
•
Avoid routing control (signal) cables in parallel with or in close vicinity of power and supply
cables.
•
Avoid close vicinity of devices generating high level of electromagnetic and/or pulse
interference (high power loads, loads with phase or group power regulation).
