Installation Instructions Chapter 2
Install the Power Supply Power supplies must be installed to the left of the adapter base unit in a position
where the 24V DC supply wiring can be kept reasonably short. Figure 25 shows
an example of a mounted power supply.
Figure 25 - Power Supply
The 1715 Redundant I/O System requires 24V DC power with a tolerance
between 18…32V DC. The system has been designed to operate with most
commercially available industrial uninterruptable power supplies (UPS). To
select a suitable power supply, calculate the overall system load that must be
powered (by using the table below), include any additional devices and add a
contingency allowance between 25…50%.
ATTENTION: To comply with the CE Low Voltage Directive (LVD), all connections
to this equipment must be powered from a source compliant with the
following:
– Safety Extra Low Voltage (SELV) or Protected Extra Low Voltage (PELV)
