Figure 18: Wiring diagram for EVA-UB4 and EVA-UB4-6

SLC Line

impedance is 50Ω at maximum and the maximum length is 2km.

Refer to the manual of control panel NFU-7000 series

to determine correct maximum loop load and maximum loop

resistance for devices connected to each loop.

Use cable AWG12-20 for wiring. Do not connect different gauge cables at one
terminal in order to prevent loosening.

! CAUTION

Do not connect cables in reverse polarity. Failure to connect the polarity correctly
could result in damage to other equipment.

! CAUTION

Figure 19: Correct and incorrect wiring method

For system monitoring

－

For terminals 1 and 6 do not use looped wire under

terminals. Break wire run to provide monitoring of connections.

! CAUTION
