9 - Ekip Maintenance

Ekip Maintenance is a signaling accessory allowing a programmable input and a programmable output
to be managed.
The module can be configured in the CB according to standard UL; the menus and information about the
module are available in the Trip unit with the names of the respective module for the IEC standard (Ekip
Signalling 1K).
IMPORTANT: each circuit-breaker can house one module only; configuration with external
modules is not allowed if an internal module is present

Connections The circuit diagrams and references concerning the terminals are available in document 1SdM000005A1001.
To connect the module to Ekip Touch and to actuator MOE-E if present, please consult document
1SdH002011A1507.

Power supply Ekip Maintenance is supplied directly by the Ekip Touch to which it is connected.
NOTE: communication between Ekip Touch and the module is interrupted in the absence
of auxiliary power supply

Input The input can be configured so that its status corresponds to actions or signals, with different
programming options (see Menu).
The module permits two logic statuses, interpreted differently by the Trip unit on the basis of the selected
configuration:
Parameter Description Contact configuration Status detected by Trip unit
Active open ON
Open Circuit open (1)
Active closed OFF
Active open OFF
Close Short-circuit (2)
Active closed ON
(1) R > 100 kΩ
(2) R (wiring + short circuit contact) <25 Ω

Output The output has three contacts: normally open (NO), normally closed (NC) and common
The output can be configured so that the contacts change status when one or more events occur, with
different programming options (see Menu).
Compared to the common contact, the NO and NC contacts have the following electrical characteristics:
Characteristics Maximum limit (1)
Maximum switchable voltage 150 VDC / 250 VAC.
2 A @ 30 VDC, 0,8 A @ 50 VDC, 0,2 A @ 150 VDC,
Breaking capacity
4 A @ 250 VAC
Dielectric strength between contact and internal 1000 V AC (1 minute @ 50 Hz).
