14 Start of operation with the Hardware
2.3 Grounding, shielding
In order to comply with Part 15 of the FCC-regulations applicable to devices of Class B, the system must
be grounded.
2.4 Devices with non-isolated power supply
The DC-supply input on the device itself (LEMO-plug, female) is not
galvanically isolated from the housing (CHASSIS):
-SUPPLY input is galvanically connected to CHASSIS internally.
That means the device's internal power supply circuitry comprises
non-isolating DC/DC converter.
2.5 Devices with isolated power supply
The DC-supply input on the device itself (LEMO-plug, female) is galvanically
isolated from the housing (CHASSIS):
-SUPPLY input is not connected to CHASSIS internally. That means the
decive's internal power supply circuitry comprises isolating DC/DC
converter.
If the device is powered by an isolated DC-voltage source (e.g. battery), use
the device’s black grounding socket ("CHASSIS") or the LEMO supply cable’s
shielding to ground the device.
2.6 Grounding with the use of the included power adapter
imc CL Devices
Use of the included table-top power adapter is protected by the power plug's protection ground
connection: at the adapter's LEMO terminal, both the (-) pole of the supply voltage as well as the
shielding and connector pod are connected with the power cable's protection ground.
