Page 7: Mounting On Equipment
Operating manual - EN 2.1 Mounting on equipment The DCM device can be fixed on the side of a power source or a wire feeder either with the factory-fitted mounting tape or with an optional DIN rail. The mounting tape can be used on any clean and suitable surface. The mounting tape counterparts are attached together on delivery. - Page 8 Operating manual - EN Let the mounting tape's adhesive cure for 30 minutes. Due to the velcro-type mounting tapes, it is now possible to detach and attach the DCM device if needed. Mounting on DIN rail (optional) Note that the rail installation typically requires drilling fixing holes on the fixing surface for the rail itself. This is not covered by this instruction.
