Solid State Logic AWS DELTA 916 Owner's Manual page 4

Introduction
P S
OWER AFETY
• This apparatus includes a universal power supply approved and certified for operation in this apparatus.
• An external disconnect device is required for this apparatus. The appliance coupler is a suitable disconnect device.
• The appliance coupler shall remain readily operable.
• Use only the Solid State Logic provided power cords. Use of any other power cord is not covered by your warranty
and may cause fire or explosion.
• The power cord must be earthed and precautions should be made so that the grounding is not defeated.
• Do not defeat the safety purpose of the polarised or grounding-type plugs fitted to the power cords. A polarised plug
has two blades with one wider than the other. A grounding type plug has two blades and a third grounding prong. The
wide blade or the third prong are provided for your safety. If the provided plug does not fit into your outlet, consult an
electrician for replacement of the obsolete outlet.
• To ensure safe operation of this apparatus, connect only to an ac. power source that contains a protective earthing (PE)
conductor. This apparatus is designed for connection to single phase supplies with the neutral conductor at earth
potential – category TN or TT – and is fitted with a protective fuse in the live conductor only. This apparatus is not
designed for use with live and neutral connections reversed or where the neutral conductor is not at earth potential
(IT supplies). This apparatus should not be connected to a power system that switches open the return (neutral) lead
when the return lead also functions as the protective earth (PE).
• An external over-current protection device is required to protect the wiring to this apparatus which must be installed
according to current wiring regulations. In certain countries this function is supplied by use of a fused plug. In other cases
a fused spur or circuit breaker should be used according to local practice.
The current requirement for this apparatus can be found in Appendix A of this manual.
• If an extension power cable or adaptor is used ensure that the total power rating of the power cable and/or adaptor is
not exceeded.
• The power cord must be kept in good condition. If the cable shows any sign of damage or if either connector becomes
loose, feels warm or appears discoloured then the power cord assembly should be replaced.
• Unplug this apparatus during an electrical storm or when unused for long periods of time.
• Do not operate this apparatus whilst it is covered or boxed in any way.
• To reduce the risk of electric shock do not perform any servicing unless you are qualified to do so.
• Disconnect the power cord before removing any panels. The power switch alone does not provide adequate isolation
for service access.
• Do not permit anyone to remove panels or covers from this apparatus other than qualified service personnel.
• Do not permit anyone other than qualified service personnel to operate this apparatus unless all panels and covers are
in place.
When installing or servicing any item of SSL equipment with power applied, when cover panels are removed:
