The TDC4 is supplied with a line cord suitable for use in the United States. In other countries, you may
have to replace the line cord with one suitable for your electrical outlet type. You must always use a line
cord with a CEE 22 Standard V female connector on the instrument end of the cable. This is the same
connector used on the US standard line cord supplied with your TDC4. Omega Engineering
(
http://www.omega.com ) is one source for international line cords, as described in their User’s Guide.
Warning
If you replace the line cord you must use a line cord rated to carry at least
10 amps of AC current. An improper line cord can create a safety hazard,
which could result in personnel injury or death.
Warning
If you replace the line cord you must use a line cord with the same polarity
as that supplied with the TDC4. An improper line cord can create a safety
hazard, which could result in personnel injury or death.
The wiring polarity of a properly wired connector is shown in the Table 1-1 for both US line cords and
European line cords that follow the "harmonized" wiring convention.

Line Cord Polarities and Colors
If you have any doubts about the line cord for use with your TDC4, please contact a qualified electrician
or instrument service technician for assistance. They can perform a simple continuity check that can verify
the connection of the TDC4 chassis to earth and thereby check the safety of your TDC4 installation.
Line Voltages
The TDC4 is designed to operate at AC line voltages between 90 and 240 VAC, 50 or 60 Hz. Unlike the
older Gamry Instruments temperature controllers, no modification of the TDC4 is required when switching
between US and international AC line voltages.
Switched AC Outlet Fuses
Both of the switched outlets on the back of the TDC4 have fuses to the left of the outputs. In accordance
with international safety standards, both the line and neutral connections are fused. The maximum
allowed fuse rating is 5 amps.
The TDC4 is provided with 5 amp, fast blow, 5x20 mm fuses in the switched outlets. The kit supplied with
the TDC4 includes three spare 5 amp fuses.
