Environmental Characteristics
Enclosure Requirements
LT system components are designed as Zone B, Class A industrial equipment
according to IEC/CISPR Publication 11. If they are used in environments other than
those described in the standard, or in environments that do not meet the
specifications in this manual, the ability to meet electromagnetic compatibility
requirements in the presence of conducted and/or radiated interference may be
reduced.
All LT system components meet European Community (CE) requirements for open
equipment as defined by EN61131-2. You must install them in an enclosure
designed for the specific environmental conditions and to minimize the possibility of
unintended contact with hazardous voltages. Use a metal enclosure to improve the
electromagnetic immunity of your LT system. Use enclosures with a keyed locking
mechanism to minimize accidents.
Environmental Characteristics
LT meets CE requirements as indicated in the table below, and is intended for use
in a Pollution Degree 2 industrial environment.
