WARNING
The BUS1000 module incorporates electronic components that might be affected by electrostatic
discharge currents flowing through certain component terminals. The main source of electrostatic
discharges is human body, especially under low humidity conditions, with carpet floors or isolating
shoes. If such conditions are present special care should be taken while manipulating BUS1000’s
modules and boards. Operators, before even touching any component, must make sure that their
bodies are not charged by either touching a grounded surface or by using an antistatic grounded
wrist bracelet.
The following hardware description is general, and includes those relevant aspects that are common to the
different equipment included in the BUS1000 system.
5.1. CABINETS
BUS1000 systems are provided in complete cabinets. They are made up of standard 19 inches wide and
four units high racks, fully wired to connecting blocks placed in the back. Connections between the different
cases are achieved only from their connecting blocks.
All the auxiliary elements, such as stabilization resistors, supply resistors, etc, are provided by the factory in
the cabinets, except for the intermediate adapting auxiliary transformers. These are provided separately for
their set-up near the main transformers, or in the boards to which their secondary currents are wired for
every position.
The cabinets are provided with a transparent front gate and a back gate, both removable for an easy access
to the cabinet during its installation.
Figure 23 shows the dimensions of the cabinets.
