Installation Notes

Housing for installation in panels, racks, or cubicles
Remove the 2 covers at the top and bottom of the front cover. Thus, 4
elongated holes are revealed in the mounting bracket and can be
accessed.
Insert the device into the panel cut-out and fasten it with four screws.
Mount the 2 covers again.
Connect a solid low-ohmic protective and operational ground to the
grounding terminal of the device. The cross-section of the cable used
must correspond to the maximum connected cross-section but must be at
least 2.5 mm
Caution
The printed circuit boards of digital equipment contain CMOS circuits.
These shall not be withdrawn or inserted under live conditions! The mod-
ules must be so handled that any possibility of damage due to static elec-
trical charges is excluded. During any necessary handling of individual
modules or printed circuit boards the recommendations relating to the
handling of electro-statically endangered components (EEC) must be
observed. In installed conditions, the modules are in no danger.
UL-certification conditions
Field Wires of Control Circuits shall be separated from other circuits with
respect to the end use requirements!
