Grab the yellow bayonet ring ➀ and pull back the bayonet ring until the latch pin clicks ➁, then turn the contact block counterclockwise and pull out ➂. Notes for removing the contact block 1. Do not attempt to remove the contact block while the operator is latched, otherwise the switch may be damaged. 2. When the contact block is removed, the monitor contact (NO contact) is closed. 3. While removing the contact block, do not use excessive force, otherwise the switch may be damaged. 4. An LED lamp is built into the contact block for illuminated pushbuttons. When removing the contact block, pull the contact block straight to prevent damage to the LED lamp. If excessive force is used, the LED lamp may be damaged and fail to light. Panel Mounting Remove the locking ring from Rubber Gasket Operator without thread TOP Marking Anti-rotation Projection Locking Ring the operator and check that the rubber gasket is in place. Insert the operator from panel front into the panel hole. Face the side without thread on the operator with TOP marking upward, and tighten the locking ring using ring wrench XN9Z-T1 or TWST-T1 to a torque of 2.5 N·m maximum. When using a nameplate When using a nameplate HNAV-, break the projection from the nameplate using pliers. Installing the Contact Block First unlock the operator button. Align the small ▼ marking on the edge of the operator with the small ▲ marking on the yellow bayonet ring. Hold the contact block, not the bayonet ring. Press the contact block onto the operator and turn the contact block clockwise until the bayonet ring clicks. Notes for installing the contact block 1. Do not attempt to install the contact block when the operator is latched, otherwise the switch may be damaged. 2. Make sure that the bayonet ring is in the locked position. Installing & Removing Terminal Covers XW9Z-VL2M To install the terminal cover, align the TOP marking on the terminal cover with the TOP marking on the contact block. Place the two projec- tions on the bottom side of the contact block into the slots in the terminal cover. Press the terminal cover toward the contact block. To remove the terminal cover, pull out the two latches on the top side of the terminal cover. Do not exert excessive force to the latches, otherwise the latches may break. IP20 Fingersafe Terminal Cover XW9Z-VL2MF To install the IP20 fingersafe terminal cover, align the TOP marking on the cover with the TOP marking on the contact block, and press the cover toward the contact block. Notes: 1. Once installed, the XW9Z-VL2MF cannot be removed. 2. With the XW9Z-VL2MF installed, crimping terminals cannot be used. Use solid wires. 3. The XW9Z-VL2MF cannot be installed after wiring. 4. Make sure that the XW9Z-VL2MF is securely installed. IP20 cannot be achieved when installed loosely, and electric shocks may occur. Notes for Operation When using the XN emergency stop switches in safety- related part of a control system, observe safety standards and regulations of the relevant country or region. Also be sure to perform a risk assessment before operation. Wiring Tighten the M3 terminal screws to a torque of 0.6 to 1.0 N·m. Contact Bounce When the button is reset by pulling or turning, the NC main contacts will bounce. When pressing the button, the NO monitor contacts will bounce. When designing a control circuit, take the contact bounce time into consideration (reference value: 20 ms). LED Illuminated Switches An LED lamp is built into the contact block and cannot be replaced. Handling Do not expose the switch to excessive shocks and vibra- tions, for example by operating the switch with tools. Other- wise the switch may be deformed or damaged, causing malfunction or operation failure. ø30 XN Series Emergency Stop Switches Place the projections on the contact block.
