2 General Information
2.1 General Safety Instructions
● Install the system only after you have read and understood the following documents:
– This document
– K-BOW Safety Instructions
– K-BOW Setup Manual
● This document is an integral part of the K-BOW system.
● Read all K-BOW documentation completely, especially
– before installing a K-BOW system,
– before the rst start-up,
– before operating a K-BOW system,
– before performing any changes,
– for regularly refreshing your knowledge about it.
● Keep the K-BOW documents for reference throughout the life of the system. Pass the
K-BOW documents on to the next owner and user of the system.
● Read the installation instructions before starting the installation.
● The system documentation must always be available at the installation location.
Thesystem documentation comprises at least the following documents:
– K-BOW Safety Instructions – K-BOW System Description
– K-BOW Installation Manual for HUB – K-BOW Installation Manual for Remote Units
– K-BOW Setup Manual – K-BOW Operation and Maintenance
● Always perform the measures described in the K-BOW documents in the sequence
speci ed.
● Observe extension cord and power strip ratings. Make sure that the total ampere rating
of all products plugged into the extension cord or power strip does not exceed 80% of
the extension cord or power strip ampere rating limit.
● Do not modify power cords or plugs. Consult a licensed electrician or your power
company for site modi cations. Always follow your local and national wiring rules.
● The K-BOW equipment is intended to be earthed. Ensure that the racks are connected
to a protective earthing conductor during normal use.
● When installing a K-BOW system, always connect it to a protective earthing conductor
rst and disconnect it last.
● The K-BOW system relies on the building installation for short-circuit (overcurrent)
protection. Ensure that the protective device is rated in accordance with the con gured
K-BOW system.
