Installation of the Device
Ambient Conditions
The operational safety and correct function of the unit depend on the location where it is
to be operated. The safety cabinet must be operated only at locations that meet the
ambient conditions listed below.
Location requirements:

The electrical system of the device has been designed for an operating height of up
to 2.000 m above sea level.

The mains power supply outlets should be out of casual reach to prevent accidental
shut-off. Ideally, the outlets should be installed above the safety cabinet and be
readily accessible.

The flooring of the location must be adequately strong and not flammable.

The support frame must be designed with an adequate load-carrying capacity
(supporting four times the weight of the device).

The room in which the device is installed must be of adequate height. For units not
connected to an exhaust system, the distance between the exhaust air opening and
the room ceiling must be at least 200 mm. There is potential to install with a lower
clearance of 200mm. This should be discussed with a Thermo Fisher Scientific BSC
specialist.

The location must be equipped with an appropriate ventilation system, see “Room
Ventilation” on page 18.

The temperature within the room must be between 10 °C and 40 °C.

The power supply voltage should not vary by ±10 % from its nominal value.

Transient overvoltage peaks shall not exceed the usual range prevailing within the AC
power supply grid. The nominal transient overvoltage level shall be the surge
withstand voltage according to overvoltage category II of IEC 60364-4-443.

An appropriate ground fault circuit interrupter must be installed by the customer to
protect the device system.

Condensation must be avoided, for example, subsequent to relocation or transport.
Should condensation exist, wait for the humidity to evaporate completely before
connecting to a power source or powering up the device.

The relative humidity in the vicinity of the device must not exceed 90 %.
NOTE Ambient conditions
If ambient conditions vary from those described above, please contact Thermo
Electron LED for assistance in installing the device.
NOTE Temporary storage
If the device is stored only temporarily (up to four weeks), the ambient
temperature may be between -20 °C and +60 °C (-4 °F and +140 °F) at a
relative air humidity of up to 90 %. For longer storage periods, the location
requirements apply.
