Safety Notice
To avoid a safety hazard, the safety notices and operating instructions provided should
be adhered to. If in any doubt, consult your supplier.
WARNING
– This system must be earthed (grounded) at all times.
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 genera-
tor 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
– 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.
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/250V).
• The system is intended for evaluation and development purposes, and should only
be operated in a normal laboratory environment, as defined by IEC 61010-1:2001.
• Clean with a dry cloth only.
• Operate flat on a bench; do not move during operation and do not block the
ventilation holes.
• The system should not be operated without all the supplied covers fully secured in
place.
• The system should not be connected or operated if there is any apparent damage
to the unit.
• The unit is designed to be connected to the AC mains supply via a standard
non-locking plug. As the unit has no mains switch, this plug constitutes the means
of disconnection from the supply, and thus, the user must have unobstructed
access to this plug during operation.
