• Provide suitable disconnect and overcurrent protection on the system side. The protection device must be located near the product where it can be operated. The OFF position must be clearly marked on the protection device.

Cables

• Always design the connection cables for the maximum anticipated current load.
• High currents and the inherent head generated by the product can cause additional heat generation at the clamping point. Plan for a correspondingly higher temperature range for the connecting cables, or reduce inherent heat by  selecting larger conductor cross-sections.
• Only one conductor may be connected to each connection point (e.g., CAGE CLAMP® connection).

Grounding/Protection/Fuses

Functions

4.1 Undervoltage and Overvoltage Detection
The product only operates in a voltage range of 18 … 30 VDC. Switching the channel on requires a minimum voltage of 20 VDC.
Undervoltage detection: If the voltage falls below 18 V during operation, the status LED flashes red/yellow at 1 Hz, and the channel trips to protect the downstream load. If the voltage returns to the nominal range (20 … 30 VDC) within  60 seconds, the channel is switched back on, and the status LED lights up green.
If the voltage drops below 18 VDC for more than 60 seconds, the channel is not switched on after the voltage returns to the nominal range, and the status LED lights up red.
The product is protected against brief voltage dips that may occur in the supply network.
For this purpose, a dead time of a few milliseconds is implemented, which ensures that the product does not trip inadvertently in such a situation.
Overvoltage detection : If the input voltage of the product rises above 30 VDC, the status LED flashes red/yellow at 5 Hz, and the channel trips to protect the downstream load. If the voltage returns to the nominal range, the channel is  automatically switched back on, and the status LED lights up green.
The following table refers to the Springfield: Sustained from the status table.

Output Status| Product Behavior in the Event of| Product Behavior When Voltage Returns to Normal

Status 6| Status 8| Status 9| Status 6| Status 6

4.2 Capacitive Load
The product can be used to switch on high capacitive loads. The resulting high inrush currents put a strain on the power supply. The power supply must be able to deliver the maximum required power without the voltage falling below 20 VDC.
The capacity value to be reached depends on fundamental factors, such as the power the properties of the load that is to be powered.
For some WAGO power supply units, possible load capacities have been determined empirically ( see Power Supplies [▶ 34] ).

Note

Measures for capacitive loads without protection against reverse discharge
Faulty tripping of channels that are connected in parallel may occur on the supply side with capacitive loads that are not protected against reverse discharge.
• In this case, WAGO recommends taking suitable measures (e.g., a diode or MOS-
FET) to decouple the capacitive load.
4.3 On Delay
As soon as a minimum input voltage is present, the channel is activated with a time delay.
This requires the channel to be switched on before the input voltage is switched off.
Note
Note the behavior when the input voltage is restored!
The circuit breaker channel switches to the status it had before the input voltage was switched off. A channel that was manually switched off tripped is not automatically switched on.
The channel is randomly activated within 0 … 500 ms with a time delay. If multiple electronic circuit breakers are connected to one power supply, this avoids larger current spikes at switch-on.
4.4 Control Input S1 and Signal Output S2
Control Input S1
A signal (15 … 30 V) between the control input and GND allows the status of the electronic circuit breaker to be changed. Which status is produced depends on the signal duration and previous status of the ECB.
Table 15: Control Input S1

Signal 1:
Reset channel.| 500 ms … 1500 ms| Status 1, 2 or 3 (depend- ing on load current): Channel switched on.| Status 6 or 7:
Channel tripped.
Signal 2:
Switch channel on.| 2000 … 4000 ms| Status 1, 2 or 3 (depend- ing on load current): Channel switched on.| Status 4:
Channel switched off.
Signal 3:
Switch channel off.| 5000 … 7000 ms| Status 4:
Channel switched off.| Status 1, 2 or 2 (depend- ing on load current): Channel switched on.

For more detailed information on individual signals and statuses, see the “General Operating Statuses” diagram in Diagnostics via Indicators [▶ 30].
Signal Output S2
The channel status can be queried at the signal output. The signal output is shortcircuit-proof and has a common potential with the power supply ground. The High signal output is not tripped.
The signal output can be configured in the default settings.
If the product has tripped, the signal output indicates this with a low signal (0 V). The signal outputs of up to 10 devices can be connected in parallel and serve as a common signal.
Note
Use signal output on a PLC!
When using the signal output on a PLC, connect the product’s power supply ground to the PLC’s ground!

4.5 Distributing and Multiplying a Potential
The product has two connection points for the positive output (connections 6 and 7) and two connection points for the negative input/output (connections 4 and 8).
Once the device is powered by a push-in type jumper bar, two load circuits can be connected directly to the device (V OUT +/GND). Additional terminal blocks can be omitted.
Observe the following note if you would like to common potentials with relays:
NOTICE
Connected relays: Only common equal potentials!
Damage to the device may occur if different potentials are communed!
If you use the relay with item no. 857-304, the potentials must only be communed via connections V IN + (connection 3) and GND (connection 8)!
4.5.1 Commoning
Push-in type jumper bars can be used to distribute an applied voltage or signal to multiple electronic circuit breakers.

• Commoning the power supply:
  The maximum supply current per connection point is 20 A. A current of 40 A can be distributed across multiple ECBs if the potential is fed in and commoned in parallel via two connection points.

• Commoning signal output S2:
  The signal outputs of up to 10 devices can be commoned and then serve as a common signal.

The respective products can be found as “related products” under www.wago.com/787-3861/400-1000.
4.5.2 Potential Distribution Module
WAGO’s Power Distribution Modules (PDM) allow parallel connection with multiple lines to the fused supply voltage and GND potential by expanding product connections Vout+ or GND ( Connections [▶ 12]).
The housing contours and dimensions are based on the electronic circuit breakers. This allows the connection from PDM to push-in type jumper bars to be made directly; see also Commoning [▶ 21]. The respective products can be  found as “related products” under www.wago.com/787-3861/400-1000.

In the connection examples given below, additional relays are connected via signal output S2. To control a relay, signal output S2 must be set to the “External Relay Control” setting (see Configuration via Button [▶ 31]).
The resulting behavior of signal output S2 can be found in table “Signal Output S2 – Signaling,” column “External Relay Control” (see Signal Output S2).
WAGO offers the following relays for both variants (connection example: relay and all pole fuse):

Switching Off a Connected Load Circuit When Product Trips

In this variant, the relay also switches off additional load circuits when the product has tripped.
Galvanic Isolation between Load Circuit and Input Potentials

In this variant, two relays ensure that the load circuit is electrically isolated from the input potentials if the product has tripped.

Note
For particularly powerful power supplies, especially with Top Boost and PowerBoost overload behavior, as well as buffering via any UPS modules (battery packs, etc.):
The circuit breaker’s integrated (device protection) fuse may trip in the event of a short circuit or when capacitive loads are charging due to the excessive overcurrent.
