3.6.2Low Voltage Control Wiring
NOTICE
Risk of control malfunction. Can cause improper unit operation. Make sure that all low voltage electrical wiring has been performed per the schematic diagram provided and that all low voltage wiring connections are tight.
A control interlock between the condenser and the indoor cooling units is required.
3.6.3Low Voltage Monitoring Wiring—TCDV Only
Condensers with monitoring terminals may be wired with Class 1 copper wire to the indoor cooling unit or other monitoring panel. Wiring must be sized so that the voltage drop in the circuit does not exceed 1 volt. Dry contacts close when a monitored event occurs. Consult condenser electrical sche- matic, supplied with the unit, for details.
Contact closure on VFD Drive monitoring terminals indicates a permanent VFD fault. A
Contact closure on TVSS monitoring terminals may indicate unit trouble ranging from electrical sup- ply issues to TVSS replacement required. A properly trained and qualified electrician is required.
3.7Electrical Connections
Electrical service is required for all models. Electrical service shall conform to national and local elec- trical codes. Refer to equipment nameplate regarding wire size and circuit protection requirements. Refer to electrical schematic when making connections. Refer to Figures 19, 20 and 21 for electrical service entrances into unit.
A manual electrical disconnect switch should be installed in accordance with local codes. Consult local codes for external disconnect requirements.
! WARNING
Risk of electric shock. Can cause injury or death.
Disconnect all local and remote electric power supplies before working in the unit. Unit contains lethal voltage in some circuits. Use voltmeter to make sure power is turned Off before making any electrical connections.
NOTICE
Installation and service of this equipment should be done only by properly trained and qualified personnel who have been specially trained in the installation of air conditioning equipment.
NOTICE
Use copper wiring only. Make sure that all conections are tight.
