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 (GND ON/OFF) to the ON-position. Digital inputs and relay outputs are also
isolated from the I/O ground.
*) Default value (X4 is GND OFF- position).
NOTE!
Internal components and circuit boards (except the isolated I/O terminals) are at
mains potential when 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 with 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
power is disconnected from the frequency converter.
