Cooling capacities at nominal / float voltage are rated at external temperatures of +35°C and +50°C respectively. Float voltage is defined at 27VDC and 54VDC.
Calculated heating capacity is rated at external temperature of -40°C, nominal voltage, and ΔT = -45°C.
3)
Controller function shall not operate the external fan during heating mode.
4)
The highest environmental protection level requires an external shroud and is defined as the protection level for the enclosure.
5)
Rating for unit without protective shroud.
6)
Max ripple 5%

Installation and Service manual
Installation:
1. The TE assembly must be mounted in a cabinet with “Hot side”
mounted externally.
2. Suitable cabinet cutout is

3. Recommended for general purposes: the TE assembly should be fastened
according to picture below so that the gasket material will seal off around
the flange of the assembly.
4.
The TE assembly is recommended to be positioned with "Cold side" in
vertical direction with wires facing downwards (heat sink fins in vertical
direction).

5. Note that condensation may occure. Standing water on the heat sink
should be avoided and drip tray may be required.
7. The power line to the assembly needs to be protected by a fuse. The fuse rating
should be of at least the nominal current of the assembly. It must withstand
150% of rated current for at least 60 seconds.
This is valid at Ta=35° Fuse ratings for other am bient temperatures (x° can

be calculated with the formula I[x°
C]=I[35°
C]/(1+0. 005*(x-35)).
This is valid when regulating with an ON/OFF regulation. At rapid temperature
cycling where this is applicable, there can be need for even higher fuse ratings.
8. Max ripple on supplied power =5%.

Service:
Fan impellers and heat sinks must be cleaned on regular intervals to reduce
risk for overheating and reduction of cooling function. The interval may vary
depending on environment.

大多数计算机拥有一系列寄存器，其存取速度比计算机主存更快。好的编译程序能进行一种被称为“冗余装入和存储的删去” （redundant load and store removal）的优化，即编译程序会在程序中寻找并删去这样两类代码：一类是可以删去的从内存装入数据的指令，因为相应的数据已经被存放在寄存器中；另 一种是可以删去的将数据存入内存的指令，因为相应的数据在再次被改变之前可以一直保留在寄存器...[详细]
