Installation
•
Connect the connection cable to the 9-pin Sub-D connector (
4
).
Secure the cable by fastening the slotted screws of the connector by means
of a torque-controlled screwdriver adjusted to
0.6 Nm
(60 Ncm).
Important:
The use of normal screwdrivers or other tools is not permissible.
Make sure to prevent any impact and tensile load to this connector indepen-
dent of the direction of action.
•
The diode current is supplied to the master system through terminals (M5)
(
1
,
3
). Fasten the M5 nuts by means of a torque-controlled screwdriver ad-
justed to
2.5 Nm
(250 Ncm).
Important
:
When connecting the cable, make sure the wires are
correctly polarized
, as
already low back voltages may lead to irreversible damage.
The use of an open-end wrench or of other radially acting levers is not per-
missible. Make sure to prevent any impact and tensile load to these terminals
independent of the direction of action.
The diode current supply must meet the following requirements:
Make sure that current and voltage spikes cannot affect the device, neither
during operation nor when switching the diode current supply ON/OFF. This
also refers to indefinite states (e.g. cable break, power failure, etc.).
Even very short current or voltage spikes may destroy the disk laser.
Very important:
It is not allowed to solder the connection cable to the high-power diode laser.
The cables must be arranged in such a way, that no induction is generated
and thus oscillations are avoided.
When the device is switched off, the device must be short-circuited to provide
ESD protection (relay contact).
Caution:
Diode current!
The device has
no current limiter.
Therefore, make sure the
maximum diode
current
is not
exceeded
.
Note:
Use a current supply module with current limiting.
The safety notes contained in these installation instructions exclusively apply, if
the parameters of the -->
Test Certificate
are complied with.
Improper use makes void any liability and warranty claims.
The measurement of the diode temperature and the LBO crystal is based on an
integrated temperature sensor (NTC; 10 k
Ω
).
The NTC resistance/temperature data is shown in -->
Appendix
,

.
The nominal temperature of the LBO crystal is adjusted through a Peltier element
with the following parameters:
