DANGER
Electrical Shock Hazard
Disconnect electric before service or maintenance.
Heater must be connected to a properly grounded electrical source.
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 10.1 illustrates the connection for heaters controlled by a line voltage thermostat.
For heaters on a low voltage thermostat, See Page 44, Section 10.2. 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 volts.
