TF-SERIES INSTALLATION, OPERATION AND SERVICE MANUAL

SECTION 11: WIRING

DANGER

Electrical Shock Hazard

Disconnect electric before service.

Heater must be properly grounded.

Failure to follow these instructions can result in death or electrical shock.

Heaters can be controlled using several methods. Normally thermostats are used to control the heaters but they can also be controlled by an Energy Management System. Section 11.1 below illustrates the connection for heaters controlled by a line voltage thermostat.

To control multiple heaters on one low voltage thermostat, See Page 47, Section 11.2. Heaters must be grounded in accordance with applicable codes: United States: refer to National Electrical Code® NFPA 70 - latest revision; Canada: refer to Canadian Electrical Code CSA C22.1 Part I - latest revision.

If any of the original internal wiring must be replaced, it must be replaced with wiring materials having a temperature rating of at least 105° C and 600 V.
