CompactBlock Guard I/O DeviceNet Safety Modules 3 North American Hazardous Location Approval The following information applies when operating this equipment in hazardous locations. Informations sur l’utilisation de cet équipement en environnements dangereux. Products marked “CL I, DIV 2, GP A, B, C, D” are suitable for use in Class I Division 2 Groups A, B, C, D, hazardous locations and nonhazardous locations only.
CompactBlock Guard I/O DeviceNet Safety Modules Environment and Enclosure ATTENTION This equipment is intended for use in a Pollution Degree 2 industrial environment, in overvoltage Category II applications (as defined in IEC 60664-1), at altitudes up to 2000 m (6562 ft) without derating. This equipment is considered Group 1, Class A industrial equipment according to IEC/CISPR Publication 11.
CompactBlock Guard I/O DeviceNet Safety Modules 5 Preventing Electrostatic Discharge ATTENTION This equipment is sensitive to electrostatic discharge, which can cause internal damage and affect normal operation. Follow these guidelines when you handle this equipment: • Touch a grounded object to discharge potential static. • Wear an approved grounding wriststrap. • Do not touch connectors or pins on component boards. • Do not touch circuit components inside the equipment.
CompactBlock Guard I/O DeviceNet Safety Modules WARNING ATTENTION If you connect or disconnect the communication cable with power applied to this module or any device on the network, an electrical arc can occur. This could cause an explosion in hazardous location installations. To comply with the CE Low Voltage Directive (LVD), this equipment and all connected I/O must be powered from a safety extra-low voltage (SELV) or protected extra-low voltage (PELV) compliant source.
CompactBlock Guard I/O DeviceNet Safety Modules 7 Observing Precautions for Correct Use The following information is related to operating directions. Refer to this information after reading the user manual that covers these modules.
CompactBlock Guard I/O DeviceNet Safety Modules Mount the Module Use these procedures when mounting the module: • Use horizontal or vertical mounting with a DIN rail that is 35 mm (1.4 in.) wide for placing the module in the control panel. • Leave at least 15 mm (0.6 in.) above and below the module for adequate ventilation and room for wiring. • Place all other heat sources an appropriate distance from the module to maintain the specified ambient temperature around the module.
CompactBlock Guard I/O DeviceNet Safety Modules 9 Wiring the Module Follow these guidelines when wiring the module: • Do not route communication, input, or output wiring with conduit containing high voltage, referring to Industrial Automation Wiring and Grounding Guidelines, publication 1770-4.1. • Wire correctly after confirming the signal names of all terminals.
CompactBlock Guard I/O DeviceNet Safety Modules Observing Precautions for Safe Use Read this for a list of precautions for safe use: • Wire conductors correctly and verify operation of the module before commissioning the system in which the module is incorporated, noting that incorrect wiring may lead to loss of safety function. • Do not apply DC voltages exceeding rated voltages to the module. • Apply properly specified voltages to the module inputs.
CompactBlock Guard I/O DeviceNet Safety Modules 11 ATTENTION Safety state of the module and its data is defined as the off state. Serious injury can occur due to breakdown of safety outputs. Do not connect loads beyond the rated value of the safety outputs. Serious injury can occur due to loss of required safety functions. Wire the module properly so that supply voltages or voltages for loads do not touch the safety outputs accidentally or unintentionally.
