Connecting the terminal blocks (optional)
The supply voltage is electrically isolated from the casing.
For devices with 2 supply voltage connections:
You have the option of supplying the supply voltage redundantly, without
load distribution.
Both supply voltage inputs are uncoupled.

WARNING
ELECTRIC SHOCK
Before connecting the electrical wires,
always
verify that the requirements
listed are complied with.
See “Requirements for connecting electrical wires” on page 11.
See “Requirements for connecting the supply voltage” on page 12.
Never insert sharp objects (small screwdrivers, wires, etc.) into the
connection terminals for electric conductors, and do not touch the terminals.
Failure to follow this instruction can result in death, serious injury, or
equipment damage.
