Observe the design of the stationary mains connection

Electrical supply
Nominal voltage
3 x 400 V + N + PE
Design according to
DIN EN 60204-1,
Clause 4.3.1
Table 25: Design of the stationary mains connection
1) Prerequisite, see chapter "7.3.5 Connecting the protective equipotential bonding conductor".
Rewinder RW500
• The customer's grounding system should have as small a grounding re-
sistance as possible (optimal would be a value < 2 Ohm), since with rel-
atively high grounding resistance levels (> 50 Ohm) the EMC filters
hardly have any more filter effect.
• The N conductor is loaded (for 400 VAC power supply).
• A right rotating field is absolutely necessary.
• The machine sockets of the MBO machines may be used exclusively for
the connection of MBO folding units, units, or deliveries.
• The 230 VAC sockets of the MBO machines may be used exclusively
for connecting auxiliary devices intended for this purpose, such as glu-
ing devices.
• All sockets (400 VAC and 230 VAC sockets) of the MBO machines
must be monitored at all times according to the corresponding federal
and local codes, guidelines and other regulations.
