SCXI-1162 User Manual
The following warnings contain important safety information concerning hazardous voltages.
Warnings:
Keep away from live circuits. Do not remove equipment covers or shields unless
you are trained to do so. If signal wires are connected to the module or terminal
block, dangerous voltages may exist even when the equipment is turned off. To
avoid dangerous electrical shock, do not perform procedures involving cover or
shield removal unless you are qualified to do so.
Do not operate damaged equipment. The safety protection features built into this
module can become impaired if the module becomes damaged in any way. If it is
damaged, turn the module off and do not use until service-trained personnel can
check its safety. If necessary, return the module to National Instruments for
service and repair to ensure that its safety is not compromised.
Do not substitute parts or modify equipment. Because of the danger of
introducing additional hazards, do not install unauthorized parts or modify the
module. Return the module to National Instruments for service and repair to
ensure that its safety features are not compromised.
When using the terminal block with high common-mode voltages, your signal
wires must be insulated appropriately. National Instruments is not liable for any
damages or injuries resulting from inadequate signal wire insulation.
When connecting or disconnecting signal lines to the SCXI-1326 terminal block
screw terminals, the lines must be powered off to avoid a shock hazard.
Connections, including power signals to ground and vice versa, that exceed any of
the maximum signal ratings on the SCXI-1162 can result in damage to any or all
of the boards connected to the SCXI chassis, to the host computer, and to the
SCXI-1162 module. National Instruments is not liable for any damages or
injuries resulting from incorrect signal connections.
If high voltages (
≥
42 Vrms) are present, the safety earth ground must be
connected to the strain relief tab. This maintains compliance with UL 1244 and
provides full protection against electric shock when the terminal block is not
connected to the chassis. To connect the safety earth ground to the strain relief
tab, run an earth ground wire in the cable from the signal source to the terminal
block. National Instruments is not liable for any damages or injuries resulting
from inadequate safety earth ground connections.
Jumper Use
All six user-configurable jumpers (W1-W6) on the SCXI-1162 are for digital communication
through the rear connector between the data acquisition board and the SCXI-1162 module. If
you are controlling the SCXI-1162 via the SCXIbus and are not using the rear connector, then
the positions of these jumpers are irrelevant.
