Parts Locator and Wiring Guide
This chapter explains how to connect signals to the SCB-68.
The following cautions contain important safety information concerning
hazardous voltages and terminal blocks.
Cautions
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 SCB-68, dangerous voltages
may exist even when the equipment is powered off. To avoid dangerous electrical shock,
do not perform procedures involving cover or shield removal unless you are qualified to do
so. Before you remove the cover, disconnect the AC power or any live circuits from the
SCB-68.
The chassis GND terminals are for grounding high-impedance sources such as floating
sources (1 mA maximum). Do
not
use these terminals as safety earth grounds.
Do
not
connect high voltages to the SCB-68 even with an attenuator circuit.
Never
