Primary side connection (push-in wiring)

DANGER

Dangerous electrical voltage leads to electric shock and arc flashover!

Non-compliance will result in death, personal injury or considerable material damage!
Ensure a safe working environment during assembly, maintenance and installation work

Before beginning any assembly, maintenance, or installation work, disconnect the system from the power supply!
Interrupt the power supply of the primary conductor and secure against being switched on again inadvertently.
Make sure that the details on the nameplate and in the “Technical data” correspond to the operating parameters of the system.

Plug and unplug the wire

The wire is connected using the direct plug-in technique,

i.e. no tools required for solid wires and ferrules, the wire is simply inserted into the contact point after stripping
Free stranded wire ends can also be connected in this way; in this case the wire clamping mechanism has to be opened by operating the pushing device.
Note the assignment of the individual primary conductors according to the printing on the top of the housing see following figure!

The wires are released via the contact release device, using a screwdriver or pushing device see figure below (A).

Notice

Do not pull the conductor when live or under load

The cables must not be live or plugged/unplugged under load.

The permitted wire cross-sections and the strip length are shown in the following table.

Wire cross-section (solid wire)	0.2 ... 4 mm²
Cable cross-section (stranded wire)	0.2 ... 4 mm²
Cable cross-section (stranded wire)	0.25 ... 4 mm² (with ferrule with plastic collar)
Cable cross-section (stranded wire)	0.25 ... 4 mm² (with ferrule without plastic collar)
Conductor cross-section AWG	24 … 10
Strip length	10 ... 12 mm / 0.39 – 0.47 in

Insert and pull the push-in service plug

The push-in plug is included.
The push-in plug is designed as a service plug. Maximum number of mating cycles: 25

For maintenance purposes, e.g. during service, the entire plug-in body can be removed from the transformer without releasing the individual wires. Proceed as follows:

Grasp the transformer housing firmly with one hand.
Press the locking tab with the thumb of your other hand and remove the plug from the housing.
Insert the plug until you hear it click into place.

Notice

Do not insert/remove the service plug under load

The service plug has no specified switching capacity and must not be plugged/unplugged live or under load.
