3.3Mechanical Installation
The NSG 1007-3 and NSG 1007-5 are completely self-contained power sources. They may be
used free standing on a bench top or rack mounted using the optional rack mount/handle kit.
The units are fan cooled, drawing air in from the sides and exhausting at the rear. The sides of
each unit must be kept clear of obstruction and a 6” clearance must be maintained to the rear.
Special consideration of overall air flow characteristics and the resultant internal heat rise must
be allowed for with systems installed inside enclosed cabinets to avoid self heating and over
temperature problems.
3.4Input Wiring – TB1
The input terminal block, TB1, is located at the rear of the unit. Ground (earth) wire must be
connected to the chassis of the AC power system. The mains source must have a current rating
equal to or greater than the input circuit breaker and the input wiring must be sized to satisfy the
applicable electrical codes. The input terminal block cover and strain relief must be installed in
table top applications to maintain protection against hazardous voltages.
CAUTION:
Capacitors in the power source may hold a hazardous electrical
charge even if the power source has been disconnected from the mains supply.
Allow capacitors to discharge to a safe voltage before touching exposed pins of
mains supply connectors.
3.5Output Power Connections – TB2
The output terminal block, TB2, is located at the rear of the unit. The external sense inputs allow
the power system output voltages to be monitored directly at the load and must be connected
either at TB2 or the load
when the sense is programmed for external. The external sense input
does not have to be connected when Internal Sense is programmed. The external sense wires
are to be connected to TB3 on the rear panel and should be run as a twisted pair for short
lengths. Sense leads over three (3) feet long should be run as a twisted shielded pair. Refer to
Figures 3-2 through 3-12 for all connections.
Note: The output of the power source is isolated from the input line and floating from
chassis ground. If needed, either side (HI or LO) may be grounded.
