Compliance
124 Block Up Converter Systems 6700/6900 series User Guide
Electrical safety
To ensure compliance with the European Low Voltage
Directive is maintained, you must install the Block Up
Converter 6700/6900 series in accordance with the following
safety precautions. These precautions must be checked before
applying power to the BUC.
The Redundancy Controller 6586 is intended for permanent
installation and is suitable for Mains Transient Voltages in
Overvoltage Category II (as identified in EN 60950-1 or
AS/NZS 60950-1 Table G.1.).
Touch temperatures at the top of the control panel of the
Redundancy Controller 6586 and the external casing of the
Block Up Converter 6700/6900 series are within allowable
limits of EN 60950-1 and AS/NZS 60950-1, but may become
high, depending on load conditions. The label indicating high
temperature areas is shown in Table 29 on page 125.
WARNING
For DC-powered BUCs, a protective earth
connection must be connected to the protective
earth terminal on the BUC (see page 126, Earth
symbols).
WARNING
For AC-powered BUCs:
• A protective earth connection must be
included in the mains wiring to the BUC (see
page 126, Earth symbols).
• As these BUCs are intended for permanent
connection to the mains supply, a readily
accessible switch or circuit breaker must be
incorporated in the mains wiring to enable
easy isolation of the unit.
• The isolating switch must disconnect both
poles simultaneously. However, if you can
positively identify the neutral conductor, you
may have a single-pole isolating device in the
live conductor.
