1. Electrical configuration
The programming feature allows to set all switching configurations ••••parallelhalf normalled top
half normalled bottom andfully normalled..... quickly and easily by jumper blocks individually for each channel.
The delivery configuration for EASY PATCH NPP-TB is "Full Normalled".

2. Grounding Variations
There are several possibilities for individual grounding. The following items correspond to thedrawing.
1. Standard grounding is to connect the ground terminals (marked with an "S") with the shieldof the incoming cable, individual grounds are not connected.
2. Connecting the pads beside the numbers 1 - 24 with some solder leads to a connection
between that channel and the common ground.
3. Connect the common ground with the chasis ground by setting the jumper to position"CHASSIS-COMMON".
4. To group ground, you have to remove the small tracks between the groups of channels.

3. Wiring
Wire are connected to WAGO spring clamping
devices. There is NO soldering or screwing
necessary. Simply insert the stripped wire (6 mm)
after pressing down the white key by means of ascrewdriver.

Lettering above the insertion holes:
T ... means TIP, R ... is RING and S ... is SLEEVE.
The corresponding channel numbers are locatedadjacent to the WAGO terminals.
The terminal will handle solid and stranded wire up to
AWG 20 (0.5 mm²). Single wires up to AWG 18(0.75 mm²) are possible.

4. Cable retention to the unit
The cable retention is at the back of the one piece metal housing. Simply put the cable onto
the prismatic bar and attach it with cable ties as shown in the drawing.
For large or thick bundles there is a rear extension bar (NPP-S) available as an option.
It can be attached with four screws to the main housing. The cable is attached to the bar in
the same manner as the standard version.
