GE Multilin L30 Line Current Differential System 11-111 MAINTENANCE 11.1 MODULES1111 MAINTENANCE 11.1 MODULES 11.1.1 REPLACE A MODULEWithdraw or insert a module only when control power has been removed from the unit, andbe sure to insert only the correct module type into a slot, else personal injury, damage to theunit or connected equipment, or undesired operation can result.To avoid damage to the equipment, use proper electrostatic discharge protection (for example, astatic strap) when coming in contact with modules while the relay is energized.The relay, being modular in design, allows for the withdrawal and insertion of modules. Modules must only be replaced withlike modules in their original factory configured slots.The enhanced faceplate can be opened to the left, once the thumb screw has been removed, as shown below. This allowsfor easy accessibility of the modules for withdrawal. The new wide-angle hinge assembly in the enhanced front panel openscompletely and allows easy access to all modules in the L30.Figure 11–1: UR MODULE WITHDRAWAL AND INSERTION (ENHANCED FACEPLATE)The standard faceplate can be opened to the left, once the sliding latch on the right side has been pushed up, as shownbelow.
