Protective insulation
4.2 Protective insulation
Danger!
Dangerous electrical voltage
If the Inverter Drives 8400 are used on a phase earthed mains with a rated mains
voltage ≥400 V, external measures need to be implemented in order to provide
reliable protection against accidental contact.
Possible consequences:
• Death or serious injury
Protective measures:
• If protection against accidental contact needs to be provided for the control
terminals of the controller and for the connections of the plugged-in device
modules, ...
– a double isolating distance must exist.
– the components to be connected must be provided with the second
isolating distance.
Note!
The protective insulation provided in the Inverter Drives 8400 is implemented in
accordance with EN 61800-5-1.

Example
Which type of protective insulation is implemented between the bus terminal of the
device module in slot MCI and mains terminal X100?
The separate potential area with the better protective insulation is decisive.
– The separate potential area of the device module bus terminal is "functionally
insulated".
– The separate potential area of the mains terminal has a "reinforced insulation".
Result: The insulation between mains terminal X100 and the bus terminal is of the
"reinforced insulation" type.

Internal switch latency
20 LEDS84AYCER EN 2.0 - 11/2010
4.5 Internal switch latency
The integrated 2 port switch causes runtime delays which can be calculated as follows:
Example:
20 process data words + 4 PROFIsafe words => 48 bytes
((36 permanent bytes + 48 bytes) x 8 x 10 nsec) + 4 μsec
(84 bytes x 8 x 10 nsec) + 4 μsec
6.72 μsec + 4 μsec = 10.72 μsec
According to the PROFINET specification, the shortest PROFINET IO telegram must have a
data length of 72 bytes. If the 36 permanent bytes are subtracted from the 72 bytes, 36
bytes are available for process data. If now less than 36 bytes of process data are used, the
PROFINET IO telegram is filled with "zero bytes" until it can be transmitted. As a
consequence for the calculation formula, the shortest PROFINET IO telegram with 18
process data words (36 bytes) has always the same length and thus the runtime delay is
the same, too.
Runtime delay = ((36 permanent bytes + process data in bytes) x 8 x 10 nsec) + 4 μsec
Note!
The use of external switches can also lead to runtime delays. Depending on the
system constellation, it may be useful to create a star topology or a line/mix
topology.
