Table 4-1 provides an overview of the Fieldgate terminals.
Table 4-1: Fieldgate terminals
4.2.2 Power supply and relay
Wire according to Fig. 4-5.
• Use a circuit breaker to isolate Fieldgate from line voltage when, e.g. wiring up.
• For switching capacity of NC relay see Table 4-1 above
• For mains supplied FXA320 Device, the user must install an external 1 A slow-blow fuse in the
power line. The fuse must be designed for min. 250 V and be approved for the application in
question.
• A total voltage of relay output and power supply lower than 300 V must be granted at
installation.
