Voltage Selection and Fusing
The Duality
F
use console uses auto-ranging power supplies so voltage range selection is not necessary. Some 3rd party
sub-systems however may have user-selectable voltage inlets. Always confirm that the input mains voltage range is set
correctly before applying power. Always isolate the mains supply before changing the input range setting.
If it is ever necessary to replace a blown mains fuse, then always use the correct rating and type of replacement. If a
correctly rated fuse continues to blow, then a fault exists and the cause should be investigated or the unit returned to SSL
for repair/replacement as appropriate.
Technical specifications can be found in Appendix A on page 50 of this manual.
Safety Earth Connection
Any mains powered item of SSL equipment that is supplied with a 3-core mains lead (whether connectorised or not)
should always have the earth wire connected to the mains supply ground. This is the safety earth and grounds the exposed
metal parts of the racks and cases and should not be removed for any reason.
Mains Supply and Phases
SSL equipment is designed for connection to single-phase supplies with the Neutral conductor at earth potential – category
TN – and is fitted with a protective fuse in the Live conductor only. It is not designed for use with Phase (Live) and Neutral
connections reversed or where the Neutral conductor is not at earth potential (TT or IT supplies).
All mains powered assemblies must be connected to the same mains phase.
Mains cables will be coded with either of the following colour schemes:
1 or 2
LIVE: Brown Black
NEUTRAL: Blue White
EARTH: Yellow/Green Green
Mains Isolation and Over-Current Protection
An external disconnect device is required for this equipment; a detachable power cord – as fitted to this equipment – is
a suitable disconnect device.
Where a mains plug or appliance coupler is used as the disconnect device, it must remain readily operable.
The power leads must be kept in good condition. If a power cable shows any sign of damage, or if either connector becomes
loose, feels warm or appears discoloured then the power lead assembly should be replaced.
An external over-current protection device is required to protect the wiring to this equipment which must be installed
according to the current wiring regulations; in certain countries this function is supplied by use of a fused plug.
Physical Safety
Console sections are too heavy for one person to lift.
If any console trim is removed then there may be sharp edges on the exposed frame metalwork.
