3.6. External interlock connection
External
interlock pins are provided for the customer’s use (see Section 4 for connection details). Any
suitable normally-open contact or solid-state switch can operate the interlock circuit. The contact or switch
should be rated for 8mA minimum at 5VDC.
The interlock circuit must be connected to enable the operation of the unit. Should the interlock connection
open during operation or standby, the source is immediately disabled, and all light output from the aperture
ceases.

EQ-400 Setup
4.1. Connections
1. Place the Controller in a standard 19-inch rack or on a stable surface. The Controller must be
placed within 3 meters of the Lamp due to the length of the interconnecting cable. See Section 10.1
for dimensional details
Note:
The Controller weighs 18.8 kg (41.5 lb). A two-person lift is recommended. Use care when
moving the Controller not to bend the fiber optic cable sharply. Minimum bend radius is 50mm.
2. Connect the Lamp unit optical output to the user equipment. It is recommended the lamp be
connected to a beam pipe. For any other use configuration shielding is strongly recommended.
The beam should always be enclosed in an appropriate beam pipe, tube, or enclosed space and
purged with nitrogen. Operating the source without any output target or beam transport is not
recommended and may lead to unsafe operating conditions. Consult Energetiq for applications
information and suggested configurations.
The Lamp should be mounted in the orientation shown in

,
with the output window on the side and the lamp mounting surface oriented horizontally.
Mounting the lamp in a different orientation will cause the plasma position inside the bulb to shift
slightly and may cause performance variations.
Setup the Lamp unit with appropriate ultraviolet, laser light, and ozone safety measures in place.
It is recommended that any enclosure or aperture-blocking hardware utilize switches wired to the
EQ-400 remote interlock circuit.
See drawing Section 10.1 for dimensional drawings.
