LT System General Implementation Rules

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
