If either the door switch or the external bus circuit opens (see Figure 13 ), the
inserted modules detect this and disable emission.

Caution: Do not short-circuit the LEMO interlock connector. Short-circuiting the in-
terlock circumvents safety regulations and NKT Photonics does not take liability
for any injuries or damage caused by doing so.
Caution: The switch connected to the interlock must be of an approved type. Fur-
ther, the switch must be installed in a manner so that its operation cannot be fixed
in the open state using a tool.
Warning: If the interlock is bypassed using an interlock defeater, personnel may
be exposed to hazardous laser radiation. To reduce the risk to personnel, the per-
son or group responsible for operation of the equipment must undertake a risk as-
sessment and provide personnel with appropriate personal protective equipment
and safety training.
