12 Check-List for Mounting
12-3
Sec. 4.2 Cabling the Ethernet modules
Does a network plan exist (4.2.4)? 
Are acceptance measurements planned or have they already been performed
(4.2.4.2)? 
Battery: Is a buffer battery installed in the Ethernet module? 
Does the buffer battery have the right polarity? 
Is an EI 811F, EI 812F, EI 813F or AM 811F module provided
to ensure battery buffering of the PM 803F? 
Are routine maintenance intervals planned for the batteries? 
Installing a 10Base2 network (4.2.5)
Are both cable ends terminated with the appropriate terminating resistors? 
Is the 10Base2 cable grounded at each AC 800F with the appropriate clip? 
Is the minimum spacing of 0.5 m between two nodes observed? 
Is the max. permissible bus cable length observed? 
Branch cables are not permissible. Is this rule observed? 
Grounding: Did you avoid shorts to ground? Did you perform the appropriate
measurements to verify? 
Were all cables laid and fastened properly. Were the cable shields put on? 
Installing a 10Base5 network (4.2.6)
Is the bus cable length a multiple or a combination of the standard lengths? 
Is the max. cable length of 500 m observed? 
Was the max. cable length confirmed by a TDR measurement record? 
Is the cable terminated at each end with the appropriate terminating resistor?
Is the bus cable grounded at exactly one point? 
Did you prevent accidental ground fault of the 10Base5 bus cable by insulating
the ungrounded terminating resistor and the N/N connectors? 
Are the transceivers attached to the cable at the marks? 
Did you measure the resistance at each transceiver with an ohmmeter to see if it
is 25 Ω between the shield contact and the core, with the terminating resistors
screwed on ? 
Is the AUI cable shield put on the contact ledge properly? Did you fasten the
cable with the appropriate clips? 
