Section 6 SETTING AND PROCEDURE FOR OPERATION
■ How to attach EMU-CT400/CT600-A
(1) Press the locking claw of the moving core, please open the moving core by removing the engagement
(Figure 1). At this time, the hinge cover opens automatically. Before inserting the cable, check the
symbols K and L to fit the current sensor in the correct direction. (The direction from the power supply
side to the load side is indicated with →. (Figure 3))
(2) After checking that the core parting faces are free from dirt, close the moving core. Push down the moving
core until the stoppers are securely locked. (Locking claw of the moving core is applied to the stopper,
you hear click.) After the stopper is securely locked, close the hinge cover. (Figure 2)
(3) Pass the tying bands into the current sensor locking holes to secure the sensor with the cable. (Figure

● Make sure that before connecting the cable, the orientation of the current sensor is correct for attachment.
K to L is the correct direction. K: power source side, L: load side.
● Do not bend the moving core in a direction other than the operation direction (shown in Fig. 1). The
current sensor may be damaged.
