3: INSTALLATION AND W IRING3-2 WEB S ERVER CPU MODULE U SER ’S M ANUAL FC9Y-B1278Assembling ModulesThe following example demonstrates the procedure for assembling the all-in-one 24-I/O type CPU module and an I/Omodule together. When assembling slim type CPU modules, take the same procedure.Disassembling Modules1. When assembling an input or output module,remove the expansion connector seal from the 24-I/O type CPU module.2. Place the CPU module and I/O module side by side.Put the expansion connectors together for easyalignment.3. With the expansion connectors aligned correctly andthe blue unlatch button in the down position, pressthe CPU module and I/O module together until thelatches click to attach the modules together firmly. Ifthe unlatch button is in the up position, push downthe button to engage the latches.• Assemble Web server CPU modules together before mounting the modules onto a DIN rail. Attempt toassemble modules on a DIN rail may cause damage to the modules.• Turn off the power to the Web server CPU module before assembling the modules. Failure to turn poweroff may cause electrical shocks.CautionUnlatch Button1. If the modules are mounted on a DIN rail, firstremove the modules from the DIN rail as described in“Removing from DIN Rail” on page 3-6.2. Push up the blue unlatch button to disengage thelatches, and pull the modules apart as shown. Whendisassembling slim type CPU modules, take the sameprocedure.• Remove the Web server CPU modules from the DIN rail before disassembling the modules. Attempt todisassemble modules on a DIN rail may cause damage to the modules.• Turn off the power to the Web server CPU module before disassembling the modules.
