Power Requirements
The MN4765B AC power adapter accepts 100 VAC to 240 VAC, 50 Hz to 60
Hz, single-phase power. The calibration module is intended for Installation
Category (Over Voltage Category) II.
3
The yellow Operate LED illuminates when the MN4765B has reached a
stable temperature and that it is ready for operation. The recommended
warm-up time is 5 minutes.
Note:
In very cold environments, it is possible the Operate LED will never
come on, which indicates the heater was not able to achieve the desired
temperature range. The module can still be used but performance may
change and no data sheet specifications or typical parameters apply for
environments outside specified calibrated temperature ranges.
4
The green Power LED illuminates when power is being delivered to the
internal bias board and that the internal high-speed photodiode is properly
biased.
Caution:
Never
input light into the MN4765B when the green LED is off.
5
FC/APC optical input connector with protective dust cap. Attach an optical
patch cord to this FC/APC connector to protect the MN4765B optical
connector from repeated connections.
6
The MN4765B is powered by an AC adapter providing 12 V DC to an
internal bias board. There is a green LED on the AC adapter to indicate
power is connected. Do not confuse this green LED with the power LED
located on the MN4765B’s top cover.
