4.1 Connecting the MGCplus in a tabletop
housing/rack frame
4.1.1 Mains connection
The NT030 and NT040 power supply units are designed for a 115 - 230 V
connector and for a maximum configuration of 16 modules and connection
boards. Voltage adaptation to a 115V/230V network occurs automatically.
The power pack fan is temperature-controlled and is automatically switched
on only when necessary.
If the MGCplus is connected with the mains cable included with delivery, a
safe and reliable connection via the protective conductor is ensured.
The power pack is protected internally with a fine-wire fuse.
CAUTION
The power supply fuse may only be replaced by the manufacturer's service
personnel!
Grounding switch
In the factory setting (
), the grounding switch connects supply voltage
zero with the protective conductor. If external devices (transducer, com
puter) have already set up this connection resulting in ground loops (hum-
pickups), the grounding switch must be opened (
).
