Thermo Scientific Revco ULT-1390-10-A, Operating Manual

Page: 17 / 110

The analog output function allows the
freezer to output signals representing
the temperature of the freezer cabinet.
The factory default setting is 4-20 mA.
Refer to Table 1-2 for output
specifications.
Insert the power cord into the power inlet module. Place the retaining
bracket (P/N 195763) over the connector. Tighten retaining screws to
secure.
Note See the serial tag on the side of the unit for electrical specifications or
refer to the electrical schematics in this manual.

The freezer should be operated on a dedicated, grounded service. Check
the voltage rating on the serial tag of the unit and compare it with the
outlet voltage. Then, with the power switch turned off, plug the line cord
into the wall outlet.
First, turn on the freezer power switch. Then open the lower front door by
grasping the bottom left corner. Locate the battery switch (Figure 1-4) and
turn it to Standby mode ( ). During initial freezer start-up, the system
battery may require charging and the Low Battery message may appear in
the message center.
Note Ensure the battery switch is turned to Standby mode ( ). The
rechargeable batteries require 36 hours to charge at initial start-up. A “Low
Battery” alarm may occur until the batteries are fully charged. Should a
power failure occur during the initial start-up period, the electronics will
have limited operation.
