S5-100U

Cabinet Mounting
Make sure that the S5-100U, the power supply, and all modules are well grounded. Mount the
S5-100U on a metal plate to help prevent noise. There should be electrical continuity between the
grounded enclosure and the mounting rails. Make sure that the system is bonded to earth.
You can use the 8LW system or the 8LX system mounting plates (see Catalog NV 21).
Adequate ventilation and heat dissipation are important to the proper operation of the system. You
must have at least 210 mm (8.3 in.) between each mounting rail (see Figures in Appendix B) for
proper ventilation.
Always locate the power supply and the CPU on the lowest tier to ensure better heat dissipation.
To measure cabinet ventilation, define the total heat loss by calculating the sum of all typical heat
losses (see Catalog ST 52.1).
