3.5 Line Power
☞
☞
Refer to appropriate figures and connect line power to TB3
terminals using the standard three-wire connection ar-
rangement.
Use wiring practices which conform 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 -- Figures 2-13, 2-15, or 2-17) for analyz-
ers with “B” prefix serial number.
The “ground symbol” Terminal 1 on TB3 (Figures
2-14, 2-16, or 2-18) for analyzers with no letter
prefix serial number.
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.
