Safety Notice

The safety notices and operating instructions provided should be adhered to, to

avoid a safety hazard. If in any doubt, consult your supplier.

WARNING – This system must be earthed (grounded) at all times.

CAUTION – The system should not be installed, operated, serviced or modified

except by qualified personnel who understand the danger of electric shock

hazards and have read and understood the user instructions. Any service or

modification performed by the user is done at the user’s own risk and voids all

warranties.

WARNING – The output terminals are NOT isolated from the incoming AC mains

supply and may be at up to 410V with respect to ground, regardless of the input

mains supply voltage applied. These terminals are live during operation AND for

five minutes after disconnection from the supply. Do not attempt to access the

terminals or remove the cover during this time.

WARNING – The unit may obtain power through the output terminals if these are

connected to a rotating motor acting as a generator. If this is the case, then the

previous warning also applies (i.e., the output terminals are live when connected

to the generator and for five minutes after the generator has been stopped). Note

that this case can arise even when the unit has been disconnected from the

incoming AC mains supply.

CAUTION – If a motor is connected to the output of this unit, the frame should be

connected to the output protective ground terminal provided. Particular care

should be taken to mechanically guard such a motor, bearing in mind that

unexpected behavior is likely to result from the process of code development.

CAUTION – For continued protection against the risk of fire, replace the fuse with

one of the same type only (i.e., Fast Act Fuse 15A/250 V).
