1.3.1 SETTLING
During transit the oil in the compressor will
have been subject to movement, so it is
important to let the cryostat settle before
switching on. We recommend the instrument
is left standing for at least eight hours, and
preferably overnight, before switching on.
Moving the instrument around on its castors,
e.g. from one laboratory to another, will not
affect the compressor oil.
1.3.2 ELECTRICAL REQUIREMENTS
The supply cord of the instrument should be
connected to any ordinary electrical outlet
(minimum 13 amps for 220/240V), a 13 amp
fuse should be incorporated in the line.
(minimum 20 amps for 110/115V) Check the
voltage stamped on the nameplate, located on
the back of the cabinet, with your supply.
The connections are:
Brown - Positive (live)
Blue - Negative (neutral)
Yellow/Green - Earth (ground)
NB.
It is recommended the OTF6000
is plugged in via an electrical surge
protection unit.
1.3.3 ELECTRICAL SAFETY
Where earth cables may have to be removed
from panels for servicing or repair purposes,
care should be taken to replace them when
replacing the panel. Earth points are identified
by a yellow and green striped circular sticker.
Where earth connections are taken through
connectors, then the connector must be
rated to take the maximum fault current.
The machine should be disconnected
before such connectors are separated for
servicing purposes.
This cryostat is fitted with an in-line mains
filter which may affect portable appliance
test results.
