22 Instructions for Use V1.3 – 10/2012
5.1 Electrical connection
5. Instrument Setup
• Have separate fuse protection provided for the electric circuit.
• Do not connect any other appliances to this electric circuit.
• The instrument is de-energized when the power cable is separated from the power supply
(power supply circuit breaker).
5.2 Prior to operation
• Check that the power supply voltage and power frequency in your laboratory match the
values on the nameplate of the instrument ( Fig. 1 ).
• Check that the drain plug is tight (in the drain hole below the left storage shelf), and press it
tightly into the drain if necessary.
During the start-up of the refrigeration system, the minimum nominal voltage must not
drop below the values specified in Chapter 3 , "Technical Data".
The compressor draws a starting current between 45 and 50 A.
Therefore, the electric circuit at the installation site must be inspected by an electrical
engineer to ensure that it meets the requirements for a smooth operation of the instru-
ment.
A stable power supply in accordance with the instrument's specifications is essential to
its proper functioning. Failure to comply with the above can damage the instrument.
Use only the power cable provided by Leica. Failure to observe this causes an imminently
hazardous situation that may result in death or serious injury to the operator or other per-
sonnel.
The drain plug must be tight in the instrument while work is being carried out in the cryo-
stat. Remove the plug only during the defrost procedure. Make sure that the drain tube
was inserted in the external container.
