ELECTROCUTION HAZARDS!
Observe the relevant safety regulations when operating electri-
cal devices.
Do not float the power supply output more than 25 V from
chassis.
Otherwise, in addition to the output voltage above 50 VDC can
increase at the terminals and present electric shock hazard to
the operator.
4.3.1 Remote Sense
Fig. 4-2 Four-wire sense connection
As shown in Fig. 4-2 the channels are intended to be operated with re-
mote sense leads (4-wire connection). The sense+ and sense- pins
provide output voltage sensing.
Use voltage protection to turn off the output and protect against extre-
mes (refer to 4.1: Operating Elements, 4.2.3: Menu).
Make sure, that the senses are properly connected.
Connect the sense inputs to the NGMO2 as close as possible to the
load’s source inputs using twisted pairs (see Fig. 4-2). This is necessa-
ry to achieve the maximum transient performance of the NGMO2.
