Memmert ICP Compressor-cooled incubators - Manual (Page 10)

10 D30374 | Date 10/2014
Construction and description
2.2 Description
The appliance can heat the interior up to 60 ºC and cool it down to -12 ºC or 0 °C (depending
on appliance size). For cooling, a compressor is used.
2.3 Material
For the outer housing, MEMMERT deploys stainless steel (Mat.No. 1.4016 – ASTM 430) and
for the interior, stainless steel (Mat.No. 1.4301 – ASTM 304) is used, which stands out through
its high stability, optimal hygienic properties and corrosion resistance to many (but not all!)
chemical compounds (caution for example with chlorine compounds).
The chamber load for the appliance must be carefully checked for chemical compatibility with
the materials mentioned. A material resistance table can be requested from the manufacturer.
2.4 Electrical equipment
►
Operating voltage and current consumption: See nameplate

►
Appliance fuse: Safety fuse 250 V/15 A, quick-blow
►
The temperature controller is protected with a miniature fuse 100 mA (160 mA at 115 V)
2.5 Connections and interfaces
2.5.1 Electrical connection
This appliance is intended for operation on an electrical power system with a system imped-
ance Z
max
of a maximum of 0.292 ohm at the point of transfer (service line). The operator
max max
must ensure that the appliance is operated only on an electrical power system that meets
these requirements. If necessary, you can ask your local energy supply company what the
system impedance is.
Observe the country-specific regulations when connecting (e.g. in Germany
DIN VDE 0100 with residual current circuit breaker).
2.5.2 Communication interfaces
The communication interfaces are intended for appliances fulfilling the requirements of
the IEC 60950-1 standard.
USB interface
The appliance is fitted by default with a USB
interface in accordance with the USB specifica-
tion. This way, you can
►
transfer software stored on a USB storage
medium to the appliance (see page 44).
►
export protocol logs from the appliance to
a USB storage medium (see page 46).
►
transfer USER ID data stored on a USB
storage medium to the appliance (see page
45).
The USB port can be found on the right side of the ControlCOCKPIT (Fig. 3).
