Refer to Figure 2-6, 2-7 or 2-8 and connect line power to
appropriate terminals on TB3 using the standard three-wire
connection arrangement.
Use wiring practices which con-
form to local codes
(example: National Electric Code
Handbook in the U.S.A.).
WARNING:
REMOVE LINE POWER WHILE CONNECTING LINE
POWER WIRES TO THE TB3 TERMINALS. ALSO,
USE ONLY THE STANDARD THREE-WIRE CONNEC-
TION ARRANGEMENT FOR SINGLE-PHASE LINE
POWER TO PREVENT AN UNSAFE CONDITION, AND
TO ENSURE PROPER ANALYZER OPERATION.
NOTE:
In all cases, connect the line power cable ground
wire (usually green) to the grounding strip at bottom
of case (5 open holes).
The “115” and “230” voltage circuits are protected with in-
ternal, board-mounted slow-blow fuses.
NOTE:
For 230 volt split phase line power, be sure to con-
form to local codes with regard to fusing the 115
volt line connected to the “N” terminal.
