4.3 Wiring Instruction
a)
Auxilairy Power Supply is needed for normal operation of WB5110-D. Please make sure using
specs of right auxiliary power supply to protect the meter from damage.
b)
Please be noticed the rated input voltage shall not be more than the meter required input voltage,
otherwise should consider using PT, and PT secondary one end should be grounded. Connector
bar is suggested for easy maitanence. And the input end of voltage is suggested to install 1A fuse
wire.
c)
Please be noticed the rated input current shall not be more than the meter required input current,
otherwise should consider using CT secondary one end should be grounded. Connector bar is
suggested for easy maitanence.
d)
WB5110-D provides wiring system of 3-phase-4-wire, 3-phase-3-wire, single phase. The on-site
wiring of the meter should be accordance with the meter required system. And make sure the
phase sequence of input voltage, current should be comformed with wiring diagram; otherwise
the error measurement will be occured.
e)
If the meter with plug-in modules, please first pull off the terminal of plug-in, then tightly press
and connect the terminal of the plug-in into the meter’s main terminals then fix the screws. And
second, please make sure the wiring of Plug-In modules and fix the screws.
5. Plug-In Modules Introduction
5.1 Switch Quantity Output Plug-In Module
The functions of relay output Plug-In modules are suitable for the alarm indication, output protection and
control. Relay output classified as normally open and normally closed.
A Upper Limit Alarm
Represents when exceed the thresh-hold value, relay output is into conduction.
B Lower Limit Alarm
Represents when under the thresh-hold value, relay output is into conduction.
C Upper and Lower Limit Alarm
Represents when exceed or under the thresh-hold value, relay output is into conduction.
D Switch Monitoring and Alarming
