AC Output Module Wiring
The AC Output Module provides eight output circuits. Each output is isolated from the other outputs. An
example of AC output wiring is shown in Figure 45. Specifications for this module and for other modules
are given in the Specifications section of this manual.

Output Loading
Voltage: 85 to 240 Vac
Maximum per output: 2.0A resistive load
Maximum per module: 8.0A
NOTE
When exceeding 1.0 A per output, it is recommended (but not required) to connect the high-current loads to
every other output - for example, outputs 1, 3, 5, 7 or 2, 4, 6, 8. This distributes heat more evenly across
the heat sink.

Jumper Comb
A ten-position jumper comb is available for inter-connecting all L1 (Hot) terminals (1, 3, 5, 7, 9, 11, 13, 15,
17, 19). See Figure 46.

Replaceable Fuses
Each output circuit on the AC Output Module includes a (plug-in) replaceable fuse.
Replacement fuse is from Wickmann, part #3741315041. This is a 3.15 Amp time lag fuse with UL/CSA
approval for 250 VAC.

Hazardous voltages exist at terminal blocks.
• Using switches at field devices, disconnect the field wiring from power sources before servicing.
Failure to comply with these instructions could result in death or serious injury.
