Conditions for installation of CU:
The central unit (referred to hereinafter as CU) is not intended for outdoor
use.
Do not install the CU on a machine or construction which is a source of
vibrations.
In order to ensure sufficient cooling free access to air must be ensured for the CU
must (it is forbidden to cover the CU, for example with a rag, or to install it in
another enclosed box).
Installation in the lift switchbox is possible if the air temperature in the this box
does not exceed the permitted limits. Remember that a higher air temperature
reduces the lifespan of backup rechargeable batteries in the CU.
It is recommended that the CU be operated in the upright position with the cable
openings at the bottom. Such a mounting makes it possible to ensure the lowest
temperatures of the rechargeable batteries and thus their longest life. Horizontal
mounting is also possible. The upright position with the cable openings at the
top (upside down) is forbidden!
After mounting the CU check that the equipment is firmly fixed in place and that
it cannot come loose and drop down the shaft.
Warning
Do not open the CU during the warranty period .
After the warranty period open it only to change the rechargeable
batteries.
