Inserting the PLUG
Follow the steps below to insert a PLUG in the device:
1. Turn off the power to the device.
2. The PLUG slot is on the top of the device housing under a cover, see Reset key
(Page 31).
3. Release the screw of the slot cover and swing the slot cover to the side.
4. The housing of the PLUG has a protruding ridge on the long side (B). The slot has a
groove at this position. Insert the PLUG correctly oriented into the slot. The PLUG is
correctly inserted when it is completely inside the device and does not jut out of the
slot.
5. Close the cover (tightening torque 0.8 Nm), to ensure that the device is closed and
water and dust proof.
