2.5 Handling of electronic equipment
A person’s normal movements can easily generate electrostatic potentials of several thousand volts.
Discharge of these voltages into semiconductor devices when handling circuits can cause serious damage,
which often may not be immediately apparent but the reliability of the circuit will have been reduced.
The electronic circuits of UAB Enilit products are immune to the relevant levels of electrostatic discharge
when housed in their cases. Do not expose them to the risk of damage by withdrawing modules
unnecessarily.
Each module incorporates the highest practicable protection for its semiconductor devices.
However, if it becomes necessary to withdraw a module, the following precautions should be taken in
order to preserve the high reliability and long life for which the equipment has been designed and
manufactured.
1. Before removing a module, ensure that you are a same electrostatic potential as the equipment by
touching the case.
2. Handle the module by its front-plate, frame, or edges of the printed circuit board. Avoid touching the
electronic components, printed circuit track or connectors.
3. Do not pass the module to any person without first ensuring that you are both at the same
electrostatic potential. Shaking hands achieves equipotential.
4. Place the module on an antistatic surface, or on a conducting surface, which is at the same potential
as you.
5. Store or transport the module in a conductive bag.
If you are making measurements on the internal electronic circuitry of any equipment in service, it is
preferable that you are earthen to the case with a conductive wrist strap.
Wrist straps should have a resistance to ground between 500k –10M Ohms. If a wrist strap is not
available you should maintain regular contact with the case to prevent the buildup of static.
Instrumentation which may be used for making measurements should be earthen to the case whenever
possible.
More information on safe working procedures for all electronic equipment can be found in IEC 60147-0F
and BS5783.
2.6 Warnings regarding use of UAB Enilit products

3.2 Rack mounting and Frame
Enilit RTU frame consists of a metal housing, an internal bus system and plug-in system components. A
standard RTU includes at least a power supply module and a central processor module. Maximum
number of 12 slots for I/O and communication modules is available.
More I/O modules can be achieved by connecting two basic frames. Second frame should have Power
Supply and can have 16 I/O or communication modules of any type. Frames are connected with external
cable for communication between CPU and modules of the second frame. Expanding Enilit RTU with
second frame, you can achieve 28 I/O modules.
For smaller installations where CPU and just one I/O card is needed could be used small frame. In the
table below it is showed possible frames configurations.
