| | | General Information | | |
| | | |
| | | Safety Precautions • In order to avoid electric shock or fire, turn power off before installation, removal, wire connection, maintenance or inspection of switch. • Follow specification when installing. Improper electrical load may damage switch, cause electric shock, or fire. | | |
| | | • Use proper wire diameter to meet voltage and current requirements. Using improper wires or incomplete soldering may cause fire due to abnormal heat generation. | | |

| | | Installation Precautions HE2B • M3 nut is inside the rubber cover. | | |
| | | • If the panel is not level when mounting an enabling switch, the waterproof feature cannot be guaranteed. HE3B • The rubber boot has a tab to be used for orientation. When making a positioning hole in a panel, do not make a hole in the rubber boot, or the waterproof feature cannot be guaranteed. When the positioning hole is not on the panel, remove the tab, but do not make a hole in the rubber boot. • When tightening the locking ring, secure the flange to prevent the enabling switch from rotating. In applications where the enabling switch is to be rotated, mount the switch in a recess on the panel as shown. | | |

| | | Use Precautions HE2B/HE3B/HE1G • To ensure the highest level of reliability connect both contacts to a monitoring device such as a safety relay. | | |
| | | HE1B/HE2B/HE3B • When installing the enabling switch ensure that it cannot be accidently activated. For example, a protrusion from a teaching pendant could cause the enabling switch to be activated by the weight of the teaching pendant. | | |
