1. Electrical configuration

The programming feature allows to set all switching configurations -

• parallel

• half normalled top

• half normalled bottom and

• fully 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 the
drawing.

1. Standard grounding is to connect the ground terminals (marked with an "S") with the shield
of 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 a
screwdriver.

Lettering above the insertion holes:
T ... means TIP, R ... is RING and S ... is SLEEVE.
The corresponding channel numbers are located
adjacent 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.
