Switches & Pilot Devices o16mm - LB Series Switches & Pilot Devices Safety Precautions * Turn off the power to the LB series control units before installation, removal, wiring, maintenance, and inspection. Failure to turn power off may cause electrical shocks or fire hazard. * To avoid burning your hand, use the lamp holder tool when replacing the lamps. * For wiring, use wires of a proper size to meet voltage and current requirements. Solder correctly according to the instructions in "Wiring" and "Notes on Terminal Cover." Improper soldering may cause overheating and create a fire hazard. Also, when using tab terminals, use receptacles of appropriate size. Instructions Removing and Installing the Contact Block 2. Use non-corrosive liquid flux. 2. Insert the contact block with the TOP markings on the contact block and the operator placed in the same direction. Then lock the units, turning the locking lever in the direction of the arrow. 1. Solder the terminals at 350C within 3 seconds using a 60W soldering iron. Sn-Ag-Cu type is recommended. When soldering, do not touch the LB series with the soldering iron. Also ensure that no tensile force is applied to the terminals. Do not bend the terminal or apply excessive force to the terminal. 1. Turn the locking lever on the contact block in the direction opposite to the arrow on the housing. Then the contact block can be removed. Signaling Lights Wiring Terminal Cover Note: When wiring, insert the lead wires into the terminal cover holes before soldering. After wiring, terminal covers cannot be installed. Relays & Sockets Solder/tab terminal Insert the terminal cover into the contact block with the TOP markings on the contact block and the terminal cover in the same direction. locking lever Panel Mounting Standard Bezel Remove the contact block from the operator. Insert the operator into the panel cut-out from the front, then install the contact block to the operator. Standard Bezel Timers Flush Bezel Panel Anti-rotation Ring Operating Environment TOP Locking Ring TOP Contactors * Do not use the LB series where corrosive gases exist or under an environment exceeding the operating temperature and humidity ranges. Otherwise, damages due to contact failure or change of surface color may occur. * Major parts of the switch are plastic. Scratches or damages may occur when scraped with a sharp object or applied with excessive load or shock. Note that this may cause operation and appearance failure of the operator and bezel. * Adherence of detergent, cutting oil, or special chemicals to the switch may result in operation failures and appearance failures such as change of surface color. Contact Block Flush Bezel Panel Contacts (micro switch) When using NC (normally closed) and NO (normally open) contacts of the same microswitch, avoid connections of different voltages, or connections of different types of power supplies. Failure to observe this instruction may cause a shortcircuit. Terminal Blocks Handling Anti-rotation Ring TOP Locking Ring TOP Contact Block Use the optional ring wrench (MT-001) to mount the operator onto the panel. Tightening torque should not exceed 0.7 N*m. Do not use pliers. Excessive tightening will damage the locking ring. 800-262-IDEC (4332) * USA & Canada 497 Circuit Breakers Notes on Mounting Switches & Pilot Devices Replacing the Lens Standard Bezel From the opposite side of the TOP marking, remove the operator (lens, marking plate, and lens holder) using the optional lens removal tool (MT-101) by gripping the recesses of the color lens.

Also, do not remove the contact block with the button in the maintained position. The contact may not operate properly when the contact block is remounted. Do not apply force to the switch guard when the switch guard is not attached to a panel. When opening the switch guard, do not open more than 180. The hinge may break. How to Install the Rubber Boot Protrusion Maintained Pushbuttons Bad Incorrect Example Example Mount Gasket * Keys are available in two types. Key numbers 0H (standard), 1H, and 2H are reversible keys which can be inserted in two ways. Key numbers 3H, 4H, 5H, and 6H are non-reversible keys. Make sure of correct insertion direction. Circuit Breakers Terminal Blocks Contactors Timers Note: Install the rubber boot before mounting the unit to the panel. * In addition to the standard key (key number 0H), six other key numbers are available. Use a key of the matching number with the key cylinder. The standard key does not have a key number indication. 500 www.IDEC.com Switches & Pilot Devices o16mm - LB Series Switches & Pilot Devices Single Board Mounting Flush Bezels The IDEC LB series is available for single board mounting.
