4.16 Installing Additional Backplane Connectors
Certain VMEbus modules require the use of a second connector on the
backplane to supply the additional current required for operation.
J2 backplanes that conform to VMEbus standards can be installed in the
PPX:575–2130 base. Two suppliers of J2 backplanes are the following:
BICC-Vero Electronics, Inc. SCHROFF, Inc.
1000 Sherman Avenue 170 Commerce Drive
Hamden, CT 06514–1336 Warwick, RI 02886
(203) 288–8001 or 800–BICC–VME (401) 732–3770
U.S.A. U.S.A.
NOTE: The use of non-SIMATIC or non-agency approved components in the
system will affect the agency approvals for the installed system. In order to
ensure a proper level of safety compliance, check with local authorities for
specific system installation requirements.
Another option for supplying the second power connector is to install a
single connector, in the form of a mini J2 backplane with a single DIN
connector and power leads, available from Siemens as PPX:2589739–8012.
Refer to the J2 connector installation instructions included in the kit for
additional details. Refer to Figure 4-31 for rear panel disassembly.
