4 Functions

4.1 Parallel Mode
Channel pairs of the product can be operated in parallel mode. The following channel pairs can be connected in parallel: · Channel 1 and Channel 2 · Channel 3 and Channel 4 · Channel 5 and Channel 6 · Channel 7 and Channel 8
To set the parallel mode, see 8 Operation in Parallel Mode [} 24].

Switch Setting in Parallel Mode

If parallel mode is selected, the desired nominal current can be set via the smaller channel of the pair. The switch setting of the larger channel is not taken into account. 10 A are added to the selected setting of the first channel. Switch positions beyond the maximum nominal current of 16 A have no effect.

Table 8: Switch Setting in Parallel Mode

Current Selector Switch Setting 1 A 2 A 4 A 6 A 8 A 10 A

In Parallel Mode 11 A 12 A 14 A 16 A 16 A 16 A

The following must be observed when operating parallel mode (see 8 Operation in Parallel Mode [} 24]): · The minimum adjustable nominal current in parallel mode is 11 A. · The maximum adjustable nominal current in parallel mode is 16 A. · If two channels are in parallel mode, both connection points must be used. Both chan-
nels must be routed and commoned externally via cables on rail-mount terminal blocks. These cables must have the same cable length and cross-section. The railmount terminal blocks connect to the load.

Asymmetric Load
If the delta I of two channels in parallel mode is > 2 A, these two channels are loaded asymmetrically. · If there is an asymmetrical load and the total current flowing for the channel pair is
< 10 A, this is indicated via the LED signaling; see 8 Diagnostics via Indicators [} 26]. · If there is an asymmetrical load and the total current flowing for the channel pair is > 10 A, the channel triggers immediately.

Product manual | Version: 1.0.0

Electronic circuit breaker

787-3668

Functions

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 Load regulation.
The capacity value to be reached depends on fundamental factors, such as the power supply already mentioned, the cable length and the conductor cross- section, as well as the properties of the load that is to be powered.
For some WAGO power supply units, possible load capacities have been determined empirically (see 8 Capacitive Switching [} 20]).
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 Button lock
The operating elements can be locked against manipulation with a button lock.
To activate/deactivate the button lock, press button 4 for > 3 seconds. After activation, the product retains its preset states.
The button lock is indicated by a cyclic yellow moving light between the channels. When the button lock is active, the product can only be controlled via the 8 Signal Input DI [} 13].
Note
The nominal current cannot be adjusted by means of a current selector switch during the button lock. If the current selector switch has been adjusted, the signal output is switched off and the respective channel LED lights up red after the button lock is disabled.

4.4 Tripping in the Event of Overload
Note
Wait for temperature to return to normal! If a channel has tripped due to a short circuit or overload, it is necessary to wait until the temperature returns to its normal range before switching the channel back on.

Electronic circuit breaker

Functions

787-3668
The product checks whether the output current is greater than the nominal current setting. As soon as the output current exceeds this nominal current, the channel is switched off. The tripping time depends on the magnitude of the overcurrent. The figure below shows the corresponding tripping times:

5.1 Sizing the Total Current Limitation

A total current limitation is implemented on the software side of the product. The product uses the software to check whether the maximum input current of Input current is maintained. The sum of all 8 channels is checked.

The following are examples of total current limitation:

If the currents are set as follows: Channel 1 Channel 2 Channel 3 Channel 4 Channel 5 Channel 6 Channel 7 Channel 8 This yields 66 A and all channels are switched on.

Table 9: Permissible total current example 66 A
8 A 8 A 8 A 8 A 8 A 8 A 8 A 10 A

If two additional channels are set to 10 A: Channel 1 Channel 2 Channel 3 Channel 4 Channel 5 Channel 6 Channel 7 Channel 8 This yields 70 A and all channels are switched on.

Table 10: Permissible total current example 70 A
10 A 8 A 8 A 10 A 8 A 8 A 8 A 10 A

Table 11: Invalid total current example: 72 A

If another channel is set to 10 A:

Channel 3

Channel 4

Channel 5

Channel 6

Channel 7

Channel 8

10 A

This yields 72 A and the channel is not switched on. Instead, the channel is blocked (see 8 Diagnostics via Indicators [} 26]) because it has exceeded the 70 A limit. If you turn a channel down again and the total cur-
rent is 70 A, the blocked channel is enabled again.

7 Installation and Removal
The product can be mounted on a DIN-35 rail.
! NOTICE
Avoid electrostatic discharge! The products are equipped with electronic components that you may destroy by electrostatic discharge when you touch. Please observe the safety precautions against electrostatic discharge in accordance with EN 61340-5-1/-3. Pay attention while handling the products to good grounding of the environment (persons, job and packing).
The DIN rail is located in the center of the vertical axis (see 8 Technical Data, Approvals, Guidelines and Standards [} 15]).

Figure 7: Position of the DIN rail
The distances from the central axis of the DIN rail to the top and bottom are 58 mm.
Mounting on the DIN rail Mount the product per EN 60715 by snapping it onto the DIN rail without any tools:

Installation and Removal

Figure 8: Mounting the product on the DIN rail
1. Tilt the product slightly. 2. Place the product, with its DIN rail guide, on the top edge of the DIN rail. 3. Press the product onto the DIN rail. 4. Press the product against the bottom fastener until you hear it lock into place.
ð If the product does not lock into place automatically, pull down the DIN rail mounting/removal latch with a screwdriver or operating tool while pressing the product onto the bottom fastener.
5. Gently shake the product to ensure that it is correctly locked into place. 6. To ensure secure fastening on the DIN rail, fit end clips on either side of the product
(with a block arrangement: on either side of the product).
Removing from the DIN Rail

Figure 9: Removing the product from the DIN Rail

8.1 Operation in Parallel Mode
ü Enable/disable parallel mode of a channel pair (example of channel pair consisting of channels 1 and 2):
· Hold down the button for channel 1 for > 3 seconds. ð Parallel mode of channel 1 and 2 is enabled/disabled. ð The function for switching the channel of button 2 on and off is disabled/enabled.
ð For all other channel pairs, the following also applies: Press and hold down buttons for the smaller channel for > 3 seconds
ü The nominal current is set in parallel mode via the smaller channel. ü This means that for channel pairs 1 and 2, the settings are made via channel 1. · Set the current selector switch from the smaller channel to the desired nominal cur-
rent. ð For all other channel pairs, the current selector switch of the smaller channel also de-
termines the nominal current of the channel pair.
