CAUTION
Risk of damage to persons
and property!
Solely permissible protective
measure in accordance with
EN 50 178: protective grounding.
Each supply cable on the card
rack must have a PE wire. To
ensure potential equalization for
all system components, the card
rack, as well as the tightening
spindles' carrying plate and the
workpiece, must be adequately
grounded.
CAUTION
Risk of damage to persons
and property!
Dangerous shock currents due to
insufficient PE wire
connections!The PE wire
connections may not be adversely
affected by mechanical, chemical
or electrochemical influences. The
connection must be permanent.
CAUTION
Risk of damage to persons
and property!
Residual currents from the
intermediate circuit and the mains
filter could disable residual-
current-operated protected
devices (RCDs). For this reason,
the card rack may not be operated
on RCDs!

Mains connection and power
consumption
Mains connection is via the mains connection
terminals - X1N1 interface. The connection
assignment can be found on the field next to
the terminals (Fig. 8).
The connection of the card rack to the mains
can either be 1-phase (1 x 230 V ±10%) or
3-phase (3 x 230 V ±10%) depending on
the power consumption. In addition to the live
lines, always connect a PE wire. The required
cross-section for the PE wire is at least
2
10 mm Cu. A permanent connection is
required for the PE wire.
