APPLICATION
These electric-finned heaters are designed to be used in small enclosures or cabinets where measuring instruments, control valves or similar equipment in hazardous areas must be heated. Vertical-finned heaters heat the area by transferring the heat to the surrounding air, creating convection current. This type of heater is recommended when it is not possible to mount a heating block directly to a flat surface. CP heaters must be installed with a thermostat to avoid damage to the heater. Thermostat models (HLTSTAT10C, HLTSTAT20C) are sold separately. If maintaining a constant temperature in the enclosure is desired, an additional temperature controller should be used.

INSTALLATION INSTRUCTIONS
MINIMUM CLEARANCES
Four M6 bolts and unistrut nuts are included in the mounting kit for attaching the heater to the unistruts as shown in Figure 1. The heater has four mounting holes in a 6.65 (169mm) square mounting pattern.

Figure 1

89115007

Alternatively, M6 nuts or bolt heads (.394 / 10mm across flats) may be slid into any of the heater fins to provide more mounting flexibility; see Figure 2:

Figure 2 Heaters are equipped with a ground terminal. Use a cable gland or a ½ NPT conduit depending on the application. Be careful not to bend or exert any load on the connection cable during unpacking and transport. To ensure effective convection, the heater should be installed with the fins positioned vertically as shown in Figure 1 on page 4. Observe the necessary clearances to the enclosure and the instruments installed near the heater as shown in Figure 3. Be sure to comply with the permissible operating temperature range. Before entering the customer-supplied Ex junction box, the connection cable must be firmly installed observing the permissible bending radius of 5 times the outside cable diameter. In dusty, hazardous areas, the applicable requirements of the EN 60079-14 have to be observed.

Adapter DO NOT REMOVE

Red Cap

Figure 4 CAUTION! Remove the RED protection cap only for ½ NPT conduit installation. Never remove the adapter. CP heaters must be installed with a thermostat to avoid damage to the heater. The heater must only be connected and secured by certified technical personnel in accordance with the label specifications, rated voltage and rated current: If operating voltage equals rated voltage, the heater will generate the specified nominal output, with an allowance to voltage fluctuations of up to 10%. Circuit breakers suitable for up to 16 amps can be used for short circuit and line protection. A ground terminal is provided for the purpose of ensuring potential equalization. The terminal is marked as such. In a TT or TN system, a residual current operated protective device (RCD) must be used with a rated response fault current not exceeding 100 mA. Residual current devices with a rated response fault current of 30 mA are preferred. When installing for an IT system application, an insulation monitor must be used that switch off the power supply as soon as the insulation resistance falls to 50 ohms per volt of the rated voltage or lower (see DIN EN 60079-14:2008; section 7.4).
OPERATION
Turn on the heater once properly installed. A safety fuse will permanently open the circuit if improperly installed.

MAINTENANCE
The heater requires no maintenance. Performance and safety tests can be conducted at intervals as determined by the operator in compliance with current regulations. Repairs must only be done by the manufacturer. In dust hazardous areas, applicable requirements of EN 60079-17 and EN 60079-19 must be observed.
SAFETY INSTRUCTIONS
Installation of the heater in an exposed position involves a certain risk of injury. The ends of the fins and hot surfaces can pose a risk of injuries.
· Maximum 160 C (320 F) with T3 heaters A non-resettable temperature limiter integrated into the heater will cut the power if it exceeds the maximum temperature. A failure could result from an external heat source, incorrect installation, working temperature too high or a technical failure. A temperature indicator shows potential problems and failures at an early stage (e.g. incorrect installation). Please check the application if more than three fields have irreversibly changed to black. The warranty is null and void if the temperature indicator has been removed from the heater.
