7. Installation
7.1 Current measurement with the module
The 800-CT24 module
· Measures current exclusively via LP current trans-
formers.
· Allows the connection of LP current transformers
with a secondary voltage of 0 ..333mV.
· Does not measure DC currents.
Please refer to the definition of the terms "current
transformers" and "current sensors" in section
Sect. “2.7 Safety information for handling current
transformers” on p. 12 in this user manual!
INFORMATION
You can configure the LP current transformer ratios
via the user interface of the basic device, possibly
the device homepage, or conveniently using the
"Device configuration" function of the GridVis
®
software.
WARNING
Risk of injury due to high currents and high elec-
trical voltages!
Severe bodily injury or death can result from:
· Touching bare or stripped leads that are ener-
gized.
· Inputs of devices, components and modules are
dangerous to touch.
Therefore, please note for your system:
· Disconnect the supply of power before starting
work!
· Secure it against being switched on!
· Check to be sure it is de-energized!
· Ground and short circuit! Use the ground
connection points with the ground symbol for
grounding!
· Cover or block off adjacent live parts!
7.2 Startup procedure/initialization
Modules started on a basic device (e.g. current
measuring modules or digital input modules) trigger
a blink interval of the LEDs. The blink interval of the
LEDs and the meaning can be found in Sect. “7.4.3
Module identification - LED blink interval” on p. 30.
WARNING
Of electrical currents and voltages!
Current transformers ../5 A (1 A) operated while open
on the secondary side (with current output on the sec-
ondary side) can result in severe bodily injury or death
(high voltage peaks).
Avoid exposed operation of the current transform-
ers. Short-circuit unloaded transformers!
ATTENTION
Incorrectly dimensioned or connected LP current
transformer connections can lead to material
damage!
Interchanged LP current transformer terminals ("k"
and "l") or incorrectly dimensioned LP current trans-
formers can lead to incorrect measurement results
and/or incorrect control behavior!
· When connecting an LP current transformer, it is
essential to observe the markings on the trans-
former!
· The polarity of the LP current transformers and
thus the "energy flow direction" runs from "k" to
"l"! The polarity of the LP current transformers
may vary depending on the model!
· Also observe the technical connection require-
ments and the markings on the rating plate of your
LP current transformers.
CAUTION
Risk of injury or damage to the device due to high
measurement currents at the connections of the
current transformers or the current measurement
inputs of the device!
High measurement currents can cause temperatures
of up to 80°C (176°F) on the connections of the
current transformers
· Use wiring that is designed for an operating tem-
perature of at least 80°C (176°F)!
· The current transformers can be hot even after
the power supply has been switched off. Allow the
connections of the current transformers and the
connecting cables to cool down before touching
them!
· Make sure that screw terminals for the current
transformer connection on the device are ade-
quately tightened!
· Ground connections present on the secondary
windings of the current transformers must be con-
nected to ground!
· Observe the general safety information for han-
dling current transformers in section Sect. “2.7
Safety information for handling current transform-
ers” on p. 12.
· Comply with the information and provisions in the
usage information of your current transformers!
