INSTALLATION INSTRUCTIONS
These steps will let you install and make the most basic operational checks. These
steps constitute the minimum safety checks that must be made whenever a
331 4A is installed
.
Note that the 3314A is a Safety
.
Class 1 instrument (provided
with a protective earth terminal).

WARNING
The 3314A should never be connected to an AC power
source without a protective earth terminal. The chassis and
all exposed shields are connected to the earth terminal and
"ttoetinq" or otherwise defeating this safety feature may
subject the operator to lethal voltages.
1. Check the 3314A for physical damage. Under no circumstances should a damaged
3314A be connected to power! Refer to the installation section of the 3314A Ser-

.
Check the line voltage selector on the rear panel. The selector setting should be
compatible with the RMS voltage of your AC power source. The 3314A can operate
from AC power sources with voltage dev
iations
from
+
5% to - 10% of the selected
.
value
.
Connecting a 3314A to an AC power source with the in-
