from the Laser Head and Model 3910
Installing the Tsunami Model 3955
Electronics Module
To release the purge line from the laser head, press inward on the metal
locking flange on the quick-disconnect, while gently pulling on the hose.
To release the purge line from the Model 3910 purge unit, press inward
on the wire clip-spring while gently pulling on the hose.
1. Verify the power switch on the rear panel is off.
2. Verify the voltage select switch on the rear panel is set to match the ac
line voltage of your facility outlet.
The white indicator for the voltage setting is located next to the power
cord connector. Voltage choices are 100, 120,220, and 240 V,,. If the
voltage setting does not match your facility outlet voltage, refer to
appendix C, "Setting the Line Voltage Switch."
WARNING
An improper voltage selection will damage the electronics.
3. Place the Model 3955 electronics module in a convenient location
within 3 m of the laser head.
4. Attach one end of the signal cable (provided in the accessory kit) to
the male D-sub TO 3955 connector on the input bezel of the laser head
(Figure 4-3), and the other end to the TO HEAD connector on the rear
panel of the Model 3955 (Figure 4-6).
5. Connect one of the BNC cables (provided in the accessory kit) to the
ML PD photodiode connector on the input bezel of the laser head
(Figure 4-3) and the other end to the PHOTODIODE connector on the
rear of the Model 3955.

WARNING
Be careful when connecting the photodiode and mode locker cables.
Connecting the Model 3955 MODE LOCKER rf output cable to the
Tsunami ML PD mode locker photodiode connector will cause permanent
damage to the photodiode pc board.
