248 | © 2023 ABB | 1SDH001330R1002 - ECN000297030
Connections
The module must be assembled in the first vacant slot of the terminal box after
Ekip Supply
, either on the
circuit-breaker (fixed version) or on the fixed part (withdrawable version).
For references about the connection and terminals, please consult document 1SDM000091r0001; use
AWG 22-16 cables with 1.4 mm maximum outer diameter for the external cabling.
To connect the module to Ekip Touch, please consult document 1SDH001000r0513.
Power supply
Ekip Com Synchrocheck
is supplied directly by the
Ekip Supply
module to which it is connected.
NOTE:
communication between Ekip Touch and the module is interrupted in the absence
of auxiliary power supply
Input
Ekip Synchrocheck
has an input (V S1 - V S2) for reading voltage, operation of which is ensured within the
ranges and with the performance given below:
Component Operating range Normal operating range Accuracy
(1)
Voltage 0÷120 VAC 10 ÷ 120 VAC 1 %
(2)
Frequency
(3)
30÷80 Hz 30 ÷ 80 Hz 0,1 %
(4)
Phase
(5)
- -180 ÷ +180 ° 1 °
(1)
the accuracy values refer to normal operating ranges, as established by IEC 61557-12
(2)
with busbar activated
(3)
with the busbar activated, frequency measurement starts at ≥ 36 V AC and ends at ≤ 32 V AC
measured voltage
(4)
in the absence of harmonic distortion
(5)
phase measurement refers to the phase difference between internal and external voltage
Isolation transformer
An isolating transformer with the characteristics given below must always be installed between the
external contacts of the circuit-breaker and the input of the module:
