Installation
Making Rear-Panel Connections
Step 7. Replace any cables previously connected to communications
ports.
Step 8. Reenergize the meter.
Output Contacts
Model 0734ES2-XX
Model 0734ES2-XX can be ordered with standard output contacts only (two
Form A and one Form C). Refer to Specifications on page 1.7 for output
contact ratings.
Standard output contacts are not polarity dependent. Solid state contacts are
recommended for KYZ operation to prevent mechanical wear.
Models 0734ES2-6X and 0734ES2-8X
Models 0734ES2-6X and 0734ES2-8X have output contacts on the following
boards:
➤ Power Supply Board: OUT101 through OUT103 (ordered as
standard output contacts only)
➤ Extra I/O Board: OUT401 through OUT404 (ordered as standard
or solid state output contacts on the 6X option; solid state only
on the 8X option)
Refer to Specifications on page 1.7 for output contact ratings.
Analog Output
Model 0734ES2-8X
Model 0734ES2-8X has four user-configurable 0–1 mA analog outputs
located on the extra I/O board. Refer to Specifications on page 1.7 for analog
output ratings.
Optoisolated Inputs
The optoisolated inputs in any of the SEL-734 models (e.g., IN102, IN404) are
not polarity dependent. With nominal control voltage applied, each
optoisolated input draws between 2–6 mA of current. Refer to Specifications
on page 1.7 for optoisolated input ratings.
Inputs can be configured to respond to ac or dc control signals via global
settings IN101D–IN102D and IN401D–IN404D.
Refer to the serial number sticker on the meter rear panel for the optoisolated
input voltage rating (listed under label LOGIC INPUT).
Current
Transformer Inputs
Note the polarity markings above terminals Z01 through Z08. Refer to
Figure 2.8 and Figure 2.9 for typical CT wiring examples.
Refer to the part number on the meter front panel for the nominal current class
rating for the phase (I
A
, I
B
, I
C
) and neutral (I
N
) current inputs.
