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.
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
Voltage 0÷120 VAC
Frequency 30÷80 Hz

Phase (5) -
(1) the accuracy values refer to normal operating ranges, as established by IEC 61557-12
with busbar activated
(2)
with the busbar activated, frequency measurement starts at ≥ 36 V AC and ends at ≤ 32 V AC
(3)
measured voltage
in the absence of harmonic distortion
(4)
phase measurement refers to the phase difference between internal and external voltage
