INSTALLATION PERSONNEL
• Only appropriately licensed professionals should install this product.
• For operator safety and to prevent ignition of flammable or combustible
atmospheres always disconnect power before servicing.
• WARNING – Substitution of components may impair suitability for
Division 2 hazardous locations.
CONTROL UNIT LOCATION
• Before installing the control unit, confirm area classification requirements.
Do not install any device that is not tagged suitable for the required area
classification. The control unit may be installed in the following areas:
o Class I, Division 2, Groups A, B, C, D
o Class II, Division 2, Groups F, G
o Class III
o Any ordinary location
• Before installing the control unit, confirm ambient temperature
requirements. Do not install any device that is not tagged as suitable for the
required temperature.
• For hazardous areas, a maximum ambient temperature of the control unit
enclosure must not be exceeded. Refer to the Temperature Considerations
section for full details.
• Do not locate the control unit in or near sources of very high electrical noise
such as a Variable Frequency Drive (VFD) or Motor Control Center. Locate
the control unit at least 10 feet from these sources and, if possible, power
the control unit from a separate power source.
Mounting: Mounting holes are integrated into the enclosure base. Mounting hardware should be
capable of supporting five times the control unit weight. Refer installation drawings for dimensions.
