Functions

4.6 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 con-
nected directly to the device (V
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 commoned!
If you use the relay with item no. 857-304, the potentials must only be commoned via
connections V
You can find a connection example in

4.6.1 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.

4.6.2 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 V
GND
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

4.7 Channel lock

The current dial can be used to set the channel lock. This setting switches off the output
of the product and the LED lights up red (see Sprungziel: Zustände, "Status 7").
In this state, the output cannot be switched on manually with a button or via the control in-
put.
