WOODWARD governor used 8446-1019

Floor and top must be electrically connected to structural frame (<2.5 mΩ). o 2 places minimum, 4 places at the corners preferred.  DIN rail must be electrically connected to structural frame (<2.5 mΩ). o Once every 300 mm (12 inches), use a minimum of 2 screws to bond a DIN rail to cabinet frame. 15.2.6.4—Cable Entry Locations  The cabinet must provide a shield termination point for cables as they enter the enclosure. Shielded I/O shields must be either AC or DC terminated directly to the cabinet (earth ground) at the entry to the cabinet, as well as connected to the FTM shield pins.  Cable shield termination hardware must be installed at cable entry points.  Cable shield terminations must be electrically connected to structural frame (<2.5 mΩ), and shall allow direct grounding or AC (capacitive) grounding of cable shields. 15.2.6.5—Equipment Zoning (Segregation) Separate the equipment inside the cabinet into areas:  Analog equipment area  Discrete I/O equipment areas  Shielded I/O area  Un-shielded I/O area  Power area  Light Industrial compliant equipment area  Monitor/kybd/pointing device (HMI if applicable)  Other equipment area Maintain a minimum of 152 mm (6 inches) of separation between areas.

Input Power Routing and Filtering 

 Input power must enter the cabinet and be routed separately from all other circuits.  Route power in middle at back of cabinet. All other I/O and internal cabling must be kept more than 152 mm (6 inches) away.  Input power must route directly to controls that are Industrial compliant.  Input power that must route to controls that are Light Industrial compliant must be filtered with a minimum of 20 dB filtering.  Input power that must be routed near other cabling will be filtered prior to the point they are on a common path and before leaving the cabinet. Filter with a 20 dB filter. Light Industrial equipment is defined as equipment that is designed and tested to comply with European Union (EU) directives (e.g. EN61000-6-1 or EN61000-6-3) for Light Industrial environments. Industrial compliant equipment is designed and tested for the EU directives for Heavy Industrial environments.15.2.6.7—Analog I/O Routing and Shield Termination I/O Module (FTM & Similar, Analog Driver, etc.) in Cabinet  Use shielded cable from MicroNet module to I/O module  Locate I/O module as close to I/O cable entry point as possible  Locate I/O module away from unshielded discrete areas (> 152 mm / 6 inches

Field I/O Cable with I/O Module 

(FTM & Similar, Analog Driver, etc.) in Cabinet  Route I/O cable against cabinet metal wall from entry point to I/O module.  Ground I/O cable shield, direct, to cabinet at entry point. o If over braid shielded, ground over braid shield to cabinet - connect inner braid shields at I/O module termination point. The inner braid must still be directly grounded to earth at one point. o If single shield, ground shield to cabinet.  If field I/O cable is grounded direct (DC coupled) at remote end of cable, ground the I/O cable shield capacitively at I/O module in cabinet and at the cable entry point into the cabinet. I/O Module (FTM & Similar, Analog Driver, etc.) not in Cabinet  Route cable from MicroNet module to I/O module with cable against cabinet metal wall  DC Ground the cable shield at entry point to the cabinet and at the I/O module. Field I/O Cable without I/O Module in Cabinet  Connect all shield braids at I/O module termination point
