Power Supply Requirements
A controller requires the following power supply sources:
 A dual redundant power supply of + 24V dc with an operating range of 18V dc to
32V dc.
Note: An AADvance controller is designed to accept supply transient and interference
according to IEC 61131 part 2.n
An over current fault in the controller must not result in the whole system losing
power. Consequently, the power sources must be able to deliver the peak current
needed to open any over current protection devices (such as fuses) without
themselves failing.
The power supply protection of the controller is within the modules, the power
distribution arrangement must provide a circuit breaker on the input side of each
power source.
Note: A controller is designed to withstand a reverse polarity connection without
permanent damage.
The power sources should come from a commercially available industrial un-
interruptible power supply (UPS) system. A suitable UPS should have capacity sufficient
to meet the entire system load (including field devices as well as the controller) and a
suitable contingency allowance for any projected future expansion.
Adding Cable Management
The field, power and other system wiring will be connected to terminals along the top
of the base units. It is recommended a length of trunking or similar be located above
each set of base units, for cable management.
