R Control Cabinet In the context of this user manual the control cabinet must fulfill the requirements on fire protective enclosures according to EN 60950 IEC 60950 UL 60950 All devices are intended for operation in control cabinets or in closed areas The LAN connection and all wire connections between the different system parts must be done via shielded cable with conductive connector shells which are fixed with screws Furthermore an additional fire protective enclosure is required which must not affect proper air circulation Safety After connecting the Crate to the mains the mains input module is powered permanently Filter and storage capacitors of the power factor correction module are charged with about 400VDC The DC On Signal as well as a power switch at control board if any installed operates as a DC on off switch only and not as a mains breaker Therefore it becomes dangerous if the box cover is open In this case a lot of components on high voltage potential get touchable Before starting any kind of work inside the power box remove the unit from mains and wait a couple of minutes with your activities Discharge the primary DC Filter capacitors by use of a well isolated 22 ohm 10W resistor 27 May 2009 Series 3000 6U VME Crate Manual 01785 A0 i Werk fiir Industrie elektroni lektror A Phoenix Mecano Company tect nile en Contents General Remarks esussssonsssnsssonssnonsssonnsnsnnsnnnnssnnns
