5.4Setting the appropriate AC voltage on TCU151

The TCU151 temperature controller works on 110/120V or 220/240V if the fuse holder is oriented in the ap- propriate position.

Note: There are two rates:

110-120V, 60Hz (USA)

220-240V, 50Hz (Europe)

5.4.1Procedure

To set the appropriate voltage on the TCU151 tem- perature controller, proceed as follows:

[1]Pull out the fuse holder (1) from the socket.

[2]Verify the orientation of the fuse holder to get the appropriate voltage. The arrow on the fuse holder (3) should correspond to the mark on the socket (2).

[3]Insert the fuse holder (1) into the socket.
