Unit Installation and Operating Environment
The
PSS‐1 unit is designed for indoor laboratory use
only.
The
acceptable operating temperature range is 22ºC to
28ºC, with a
relative humidity of 45% to 75% non‐
condensing,
at a maximum altitude of 2000m above sea
level.
If the
unit is stored in conditions outside of these
ranges,
it must be left
to stand unpowered until it has
acclimatised
to within these environmental limits before
being
powered.
Use
only the AC mains power cord provided with the
unit
or as specified Section 4.
The
unit must be connected to a suitably earthed mains
supply,
with appropriate earth‐leakage and over‐current
protection
.
Always
ensure that the mains power connector is
securely
inserted into the rear of the unit, and any
excess
power cord does not pose a potential trip or pull
hazard.
The power
for this unit must come from a stable mains
supply.
Do not power
from inverters, frequency convertors, or
generators.
This unit
requires a power supply with both a stable
voltage
and stable frequency. Inverters, frequency
convertors,
and generators do not provide acceptable
stability
and the unit can perform outside its
specification, or
fail to perform, or be damaged by the
use of these
forms of power supply.
