6
Disconnect the CN5 thermal switch relay
connector.
7
Disconnect the relay connectors for the
LD power supply, Peltier power supply,
and relay.
8
Unplug the signal line connector,
keeping it level as you pull it out.
Shorting pins are inserted during storage or transport to prevent electrostatic
discharge damage to high-output semiconductor lasers.
When inserted the shorting pin into the red and black terminals, it forms a closed
circuit in the LD.
Be sure to open the circuit before connecting the marker to a power supply. To form
an open circuit, remove the end of the pin from the black terminal and insert it in the
other red terminal. The LD may be damaged if the marker is turned on with the pin
accidentally inserted into the red and black terminals.
