1SDH002031A1002 ECN000092998 Rev. B SACE Tmax XT2 – XT4 | 170
Consult
the electrical diagrams for 1SDM000068R0001 to connect the module to its
communication network and for terminal references.
For external cabling, AWG 22-16 cables with a maximum external diameter of 1.4 mm
must be used
the instruction sheets 1SDH002009A1503 to connect the module to Ekip Supply and
Ekip Touch
Ekip Com Synchrocheck is supplied directly by the Ekip Supply module to which it is connected .
NOTE: in the absence of an auxiliary supply, the communication between Ekip Touch
and module is interrupted
Ekip Synchrocheck has an input (V S1 - V S2) for reading voltage, the operation of which is
ensured in the following ranges and with the following performance:
Normal operating interval
NOTES:
(1) with busbar active
(2) with busbar active, the measurement of the frequency starts with
36 VAC
measured voltage and stops with
32 VAC measured voltage
(3) in the absence of harmonic distortion
(4) measurement of the phase refers to the phase difference between internal and
external voltage
(5) The accuracy values refer to normal operating intervals according to IEC 61557-
12
Isolation transformer
Between the external contacts of the switch and the input of the module, an isolation transformer
must always be installed that has the following characteristics:
fixing: EN 50022 DIN43880 guide
material: self-extinguishing plastic
protection level: IP30
electrostatic protection: with screen to be earthed
accuracy class: 0.2
performance 4 VA
overload: 20 % permanent
insulation: 4 kV between inputs and outputs, 4 kV between
screen and 4 kV outputs between screen and inputs.
frequency: 45-66 Hz
