It is sometimes necessary to remove the internal unit from the case to make adjustments and carry out maintenance on the instrument This section describes the procedure for removing the internal unit in such cases To remove the internal unit it is not necessary to remove the terminal board wiring Because the internal unit and the terminal board case are connected by a multipin connector separating them at this connector enables the internal unit to be removed from the case while leaving the wiring to the terminal board in place However if there is wiring to the contact signal terminals on the front of the internal unit or if it is a terminal connected power wired model that wiring must be removed 1 Unplug the power cord from the receptacle 2 Pull the terminal cover down toward you The cover also serves as a handle for removing the internal unit Hook your fingers around the terminal cover and pull out the internal unit Figure 2 9 Figure 2 10 Internal Unit Removal 2 IM 19B01E04 02E lt 2 Installation gt 2 7 2 6 External Wiring 1 Mount round M4 screw crimp terminal lugs on the wires to be connected to the terminals 2 Ifthe internal unit is already installed in the rack case pull the terminal cover down away from the terminals and connect the wires Wiring to the terminals on the internal unit such as wiring to the contact signal terminals should also be done with their terminal covers removed
