Power Safety
• 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. f 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
( T 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. n certain countries this function is supplied by use of a fused plug. n 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.
• f an extension power cable or adaptor is used, ensure that the total power rating of the power cable and/or adaptor is
not exceeded.
• 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.
