Installation
Site Selection
When selecting a site for the TCU, keep the following in mind:
•
The TCU requires a 120 VAC power supply.
• The TCU is designed to operate at a recommended temperature range of -10°C to 60°C (14°F to
140°F). The upper temperature limit is 50°C (122°F) when using the recommended backup
battery.
• The TCU is intended to be permanently installed in a NEMA 12 or higher rated panel that
prevents access to live parts without a tool.
•
Attention should be given to the location of the TCU to provide accessibility for wiring and
servicing. Leave enough space around the TCU to access the TCU’s fuse and to remove the
connectorized terminal strips. Install the TCU in the panel at a position where the LCD display
can be read comfortably. The LCD is best viewed at slightly below eye level.
Pre-Installation Modification
Use snips, pliers, or a razor to remove the retention
clips from P-connectors.
Once the retention clip is removed, the P-connector
will be able to be used with the TCU800.
