Designation: AIR CONDITIONER FOR ELECTRICAL ENCLOSURE
Page 10/20
UMA-CDZ-IP-ACIRM100-00
Upstream of the electrical connection, an efficient disconnection
system must be provided and it must be clearly identified
Air conditioner is already fitted with a temperature controller, no
additional temperature control must be connected upstream of
the unit.
4 - STARTING AND ADJUSTMENT
4.1 GENERAL DESCRIPTION
Air conditioners are especially designed for dissipation of heat loss inside electrical
enclosures with IP54 protection degree.
Air circulation inside the enclosures allows to keep enclosure air volume isolated from
external ambient air, it preserves the inside of the enclosure against dirt and humidity
which are present in the external air.
IP-ACIRM series must be installed only on the roof of electrical
enclosure
After finishing assembly of the conditioner, wait approx. 30 min.
before starting it (the oil must collect in the compressor to ensure
lubrication and cooling).
The air conditioner operates automatically, that is to say, after insertion, the evaporator fan
operates continuously making the air inside the cabinet circulate. This way a uniform
distribution of temperature inside the cabinet itself is attained. The built-in thermostat
drives compressor and condenser fan according to set point value and other parameters
(See PARAMETERS at
4.2 DIGITAL THERMOSTAT INSTRUCTION
section for
references)
Compressor and condenser fan start after a delay set on thermostat (see parameter AC on
parameters list for references) to permit a
minimum interval between the compressor stop
and the following restart.
During proper operations, the compressor and condenser fan
turn OFF when internal enclosure temperature decreases under
set point value.
