Table 2 -1 Specifications. (All the control connections are not found on every I/ O -expander board, for
specific information see Chapters 1 and 4 .)
The control connections are isolated from the mains potential and the I/ O ground is
connected to the frame of the inverter via a 1 -M
Ω
resistor and 4 ,7 -nF capacitor* ). The
control I/ O ground can be connected directly to the frame by changing the position of the
jumper X4 (G N D O N / O FF) to the O N -position. Digital inputs and relay outputs are also
isolated from the I/ O ground.
* ) Default value (X4 is G N D O FF- position).
N O TE!
Internal components and circuit boards (except the isolated I/ O terminals) are at
mains potential w hen the frequency converter is connected to the mains. This
voltage is extremely dangerous and may cause death or severe injury if you
come into contact w ith it.
The control I/ O terminals are isolated from the mains potential, but the relay
outputs and other I/ O 's may have a dangerous voltage connected even if the
pow er is disconnected from the frequency converter.
