1/ There are several variations in power supply design, some have a meter and some not. There are also third party power supplies for this model of laser. This information is provided as a guideline only. If you are not sure which power supply you have, check with the vendor or American Laser before making connections.

2/ There is some variation in the colours used for the solenoid wires - some use the scheme shown above while some have the same colours for both solenoid wires.

3/ Not all models have integrated intake fans powered through the umbilical. Most have fans powered externally from a user provided connection. The power between pins 2-6 and 2-8 is typically the same as the line power (220 Vac).

4/ Not all models are equipped with a light control card, or the light control card may be disabled - check your documentation or check with the vendor.

5/ On some third party power supplies the case ground is located on pin 1-7 and light card supply voltage is located on 2.12 - check your documentation or check with the vendor to determine if a light card is present and what voltages/pins must be connected.
