HVI SPECTRUM
Instruction Manual
Uster Technologies, Inc. Chapter 2
Installation • Page 2-2
Specific electrical requirements and connection procedures for the
HVI
SPECTRUM
instrument are provided in this chapter
.
These instructions
MUST be performed for each cabinet at the time of installation with the
assistance of an Uster Technologies’ service technician.
2 Electrical Requirements
The
HVI SPECTRUM
instrument operates on 208 or 230 volts ± 10%
(single phase) (47 to 63 Hz) and requires a separate dedicated 20-amp
circuit breaker at the facility’s electrical load center. During normal
operation, the
HVI SPECTRUM
draws approximately eight (8) amps; the
startup current is sufficiently high to require the larger breaker. A power
cord is provided that will connect to the
HVI SPECTRUM
. The opposite
end must be fitted with connections compatible with the facility’s
electrical system. An uninterruptible power supply (UPS) is suggested.
Power Line: Single phase main with protection switch.
If these conditions cannot be met, a power regulator must be installed.
It is recommended that you use SOLA #63-23-220-8 (60 Hz), #63-23-
720-8 (50 Hz), or an equivalent.
2.1 Required Laboratory Conditions
It is recommended that the instrument be operated in a controlled
environment, as follows:
Humidity 65% (+/-2%)
Temperature 20°C (+/-2°) / 68°F (+/-4°F)
Fiber samples should be properly conditioned in the laboratory
environment to maintain consistent results.
