Getting Started
Power connection
This instrumen
t operates from a single-phase power source with the neutral
conductor at or near earth ground. The line conductor is fused for over-current
protection. A protective ground connection through the grounding conductor in
the locking power cord is essential for safe operation.
CAUTION. The instrument does not have a power switch. When you connect
the power plug to one of the AC line connectors, and the Power Supply module
for that slo
t is installed, the instrument powers on. If you have only one power
supply installed, be sure to connect the power plug to the correct rear-panel
power connector.
