CompactBlock Guard I/O EtherNet/IP 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 EtherNet/IP 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 EtherNet/IP 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 EtherNet/IP 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 EtherNet/IP 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 EtherNet/IP Safety Modules Setting Network Address Set network (IP address). The module ships with the rotary switches set to 999 and DHCP enabled. To change the network address, you can: • adjust the switches on the front of the module. • use a Dynamic Host Configuration Protocol (DHCP) server, such as Rockwell Automation BootP/DHCP. • retrieve the IP address from nonvolatile memory. The module reads the switches first to determine if the switches are set to a valid number.
CompactBlock Guard I/O EtherNet/IP Safety Modules 9 When the module is reading the network address set on the switches, the module does not have a host name assigned to it or use any Domain Name System. If the switches are set to an invalid number (such as 000 or a value greater than 254), the module checks to see if DHCP is enabled. If DHCP is enabled, the module asks for an address from a DHCP server. The DHCP server also assigns other transport control protocol (TCP) parameters.
CompactBlock Guard I/O EtherNet/IP Safety Modules • Pry open the two gray latches to lock them in the open position. Hook the module over the top of the DIN rail. Rotate the module downware until it makes full contact with the DIN rail. Snap the latches back into place to secure the module to the rail. Verify that the module is securely attached to the DIN rail. Hook and rotate module on DIN rail. Snap latches into place.
CompactBlock Guard I/O EtherNet/IP Safety Modules 11 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 EtherNet/IP 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 EtherNet/IP Safety Modules 13 • Be sure that AC voltage is never applied to the module as module failure will result. 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.
