For every supply voltage to be connected, perform the following steps:
Ensure the required conditions for connecting the supply voltage are
observed (see page 5 “Supply voltage”).
Remove the power connector from the device.
Connect the lines for the supply voltage to the + and − terminals.
Note: With non-redundant supply of the mains voltage, the device reports
a power failure. You can prevent this message by applying the supply
voltage via both inputs, or by changing the configuration in the
Management.
Signal contact
For the signal contact to be connected, make sure the following
requirements are met:
The lines to be connected are voltage-free.
The connected voltage is limited by a current limitation device or a
fuse.
Observe the electrical threshold values for signal contact (see on
page 40 “General technical data”).
Connect the signal contact lines to the terminal block.
WARNING
ELECTRIC SHOCK
Only start connecting the supply voltage if all the above mentioned
requirements are fulfilled.
See “Supply voltage” on page 5.
Failure to follow these instructions can result in death, serious injury,
or equipment damage.
