WARNING
Initial visual inspection
After unpacking the instrument, inspect the shipping container and its cushioning material for
signs of stress or damage. If damage is identified, retain the packing material for examination by
the carrier in the event that a claim is made. Examine the instrument for signs of damage; do not
connect the instrument to a supply when damage is present, internal electrical damage could result
in shock if the instrument is turned on.
Mounting arrangements
Excessive temperatures may affect the performance of the instrument. Completely remove the
plastic cover, if one is supplied over the case, and avoid standing the instrument on or close to
other equipment which is hot.
Installation requirements
Ventilation
This instrument is forced-air cooled by a fan mounted on the rear panel. Air must be allowed to
circulate freely through the ventilator grills located on the side and underside of the instrument.
Before switching on the instrument, ensure that the fan outlet on the rear panel is not restricted
(i.e. clearance of at least 75 mm (3 in) at the rear, 25 mm (1 in) at each side, 15 mm (0.5 in) on the
underside). Failure to provide adequate clearances will increase internal temperatures and reduce
the instrument’s reliability, so that its performance may not meet specification.
Class I power cords (3-core)
General
When the equipment has to be plugged into a Class II (ungrounded) 2-terminal socket outlet, the
cable should either be fitted with a 3-pin Class I plug and used in conjunction with an adapter
incorporating a ground wire, or be fitted with a Class II plug with an integral ground wire. The
ground wire must be securely fastened to ground. Grounding one terminal on a 2-terminal socket
will not provide adequate protection.
In the event that a molded plug has to be removed from a lead, it must be disposed of immediately.
A plug with bare flexible cords is hazardous if engaged in a live socket outlet.
Power cords with the following terminations are available from IFR Ltd. Please check with your
local sales office for availability.
