Installation instructions
Forreasonsofsafetyitisnotpermissibletoconnectlowvoltages(upto50V)
andhighervoltages(50 … 250V)tothesamemodule.
IfaPCDmoduleisconnectedtoahighervoltage(50 … 250V),approved
components for this voltage must be used for all elements that are electrically
connected to the system.
Usinghighervoltage(50...250V),allconnectionstotherelaycontactsmustbe
connected on the same circuit, i.e. in such a way that they are all protected against
one AC phase by one common fuse. Each load circuit
may also be protected individually.
I/O modules and I/O terminal blocks may only be plugged in and removed when the
PCD and the external +24 V are disconnected from the power supply.
The Annex, Section A.4 "Relay contacts" contains measurement details and
suggestedwiringfortherelaycontacts.Forsafeswitchingandalongservicelife,
theseguresmustbeobserved.
