SPECIFIC
CAUTIONS
For analog input channels, if the fused AI IFP/LFP option is selected
to power a 4 to 20 milliampere input, removing the I/O module from
the base in nonredundant applications will result in a loss of power
to all input current loops. (p. PR6-1, PR8-1, PR11-1, PR28-1)
Insure the setting for the digital input field power monitor jumper
DIFP-J2 matches the actual field power voltage (IFP or LFP). Circuit
damage will occur if the LFP voltage is greater than the voltage set-
ting of jumper DIFP-J2. (p. PR12-1)
Use only ABB Automation approved relays on the relay assembly.
Using unapproved relays could improperly route signals and dam-
age equipment connected to the relay and the relay itself. CSA cer-
tification is voided when unapproved relays are used. (p. PR16-1,
PR32-1, PR33-1, PR34-1)
