2. Installation and Service
2.1. Unpacking
The package should be opened in an electrostatic discharge (ESD) free environment. The operator
should be properly grounded at the same level as the working surface. The device should be unpacked
on an ESD free surface. The laser source electronics and pump diodes can be seriously damaged by
electro-static discharge. Even if damage is not immediately apparent, it may shorten the lifetime of the
unit, in particular the pump laser.
Handle the device with care when unpacking. Hold the box in one hand and the fiber in the other hand
when pulling out the unit from its packaging. Lay down the device and the fiber on a horizontal surface.
Before any operation, make sure the device is free from mechanical damage, which may have occurred
during transportation.
The device is supplied by Keopsys completely assembled and tested.
Keep the original shipping container for use in case the instrument needs to be returned to Keopsys
for repair or servicing.

WARNING
This operation has been made sure by appropriate design of the power cord
and the device mains plug so never change the cord delivered by KEOPSYS
to another type
This operation is normally due to an external solicitation of the device for instance an over-load on the
power line.
Remove the power cord: the power connector on the device has been designed in a way it is impossible
to change mains fuses when power cord is plugged in.
Lift up the plastic cap using the end of a flat screwdriver.
Remove the fuses and change to exact types as described in fuse chart (please note that there are 2
fuses on the mains).
If the amplifier does not work properly after this operation, ensure the line and the fuses are correct. If
it is the case, enquire about this problem to KEOPSYS.
