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
1SDM000002A1001 and
1SDM000019A1002 ; 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 1SDH002009A1505 .
Power supply Ekip Com Signalling 2K 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 Touch can be configured so that the status of the inputs corresponds to actions or signals, with different
programming options (page 172).
The connection of each input (H11 and H12 for model 2K-1, H21 and H22 for model 2K-2, H31 and H32 for
model 2K-3) must be made with reference to the common contacts (HC).
The module permits two logic statuses, interpreted differently by Ekip Touch depending on the configuration
selected for each contact:
State Electrical condition Contact configuration Status detected by Trip unit
Open Circuit open
(1)
Active open ON
Active closed OFF
Closed Short-circuit
(2)
Active open OFF
Active closed ON

(2)
R ( short circuit contact) <25

Output
Ekip Touch can be configured so that the contacts of each output are closed or opened upon the occurrence
of one or more events, with different programming options (page 172).
The output of each module consists of 2 contacts (K11-K12 and K13-K14 for model 2K-1; K21-K22 and
K23-K24 for model 2K-2; K31-K32 and K33-K34 for model 2K-3), which are isolated from the unit and from
the other outputs, and have the following electrical characteristics:
Characteristics Maximum limit
(1)
Maximum switchable voltage 150 VDC / 250 VAC
Breaking capacity
2 A @ 30 VDC, 0,8 A @ 50 VDC, 0,2 A @ 150 VDC,
4A @ 250 VAC
Dielectric strength between open contacts 1000 V AC (1 minute @ 50 Hz).
Dielectric strength between each contact and coil 1000 V AC (1 minute @ 50 Hz).
