ASSEMBLY CAUTION/WARNING:

Keep terminal cover closed and cable gland secured while in presence of hazardous atmosphere.

Open all circuits to this product prior to removal of terminal block cover.

Electrical installation shall use standard EN/IEC 60079-14 and/or NEC Class 2 circuit specifications. UL certified installations

require the use of a sealing fitting certified to 60079-0 Ex d IIB within 18 in. (46 cm) of the encoder. Terminal block covers are

marked near the threaded hole with the basic thread size to aid with selection of fittings or glands. Conductor insulation must

be rated for at least 105°C ambient temperature. External case ground connection is provided by means of a screw and ring

type terminal which accepts up to 10 AWG (5.26 mm2) size conductor.

The customer shall use our products according to our specifications and to the manners of the profession. BEI Sensors will not be
