摘要： To prevent damage to the electrical connections between PLC modules and a backplane during seismic and other vibrational disturbances, a bracket is used having two parallel side members attached to the backplane and a lower support bar connected between the side members to support the PLC modules in the vertical direction. An upper support bar may also be provided between the side plates to hold the PLC modules in the bracket and further prevent vertical movement. The upper and lower support bars may also provide vertical members or a rest in contact with the PLC modules and having a high coefficient of friction to prevent lateral movement of the PLC modules with respect to the backplane.
