WARNING
1. Verify field power is turned off before starting the replace-
ment procedure. Failure to do so could result in severe or fatal
shock. Do not turn the power on until the replacement proce-
dure is complete.
CAUTION
1. Use only ABB Automation approved relays on the relay
assembly. Using unapproved relays could improperly route
signals and damage equipment connected to the relay and the
relay itself. CSA certification is voided when unapproved
relays are used.
