6. Outline Drawing, Installation Dimension and Coil Drawing: ( tolerance±1mm )

① Outline drawing and installation dimensions are shown in Figure 1:

② The coil diagram is shown in Figure 2:

● Description: Each product is supplied with two sets of floor feet, two sets of busbar feet and screws for fixing the busbar. See below for installation instructions.

③ Installation instructions :

● When fixing to the bottom plate :

Take the two feet ( supplied with the product ) and insert them into the foot sockets on the bottom plate as shown in Figure 3 on the right. The center distance of the installation holes is 68×104.7 ; the diameter of the mounting holes of the feet is Φ5.0 ; the transformer can be fixed on the bottom plate with M5 screws.

● When fixing on the busbar :

Insert the two feet with M5 holes (supplied with the product ) into the slot of the busbar feet as shown in Figure 3. The center distance of the M5 holes is 59 , and the transformer can be fixed on the busbar with M5 screws.

7. Typical application and performance parameters:

When the sampling voltage is obtained directly by the resistance method ( as shown in Figure 4) , the performance parameters are shown in Table 1.

8.Attention:

① Connect the primary winding of the current transformer in series with the loop of the measured current. Operate the secondary winding in a near short-circuit mode.

② Do not allow the secondary circuit of the current transformer to be open-circuited. Do not connect any fuse in the secondary loop.
