Minimum cabling required
An ancillary bridged connector DB37 is included with each laser for the purposes of shunting the external safety
device. This accessory allows the laser to be used without being integrated. Retain the connector to check the
operation of the marking machine independently of its integration.
The contact(s) 1-20 / 2-21 / 3-22 / 4-23 / 5-24 / 12-30 is/are bridged. This equates to shunting the emergency
stop, interlock, reset and key contact.
