Site Preparation
This section provides in-depth information about the environmental conditions that are required in the area
where the UPS is installed, in order to achieve best-in-class results. In order to operate at full capacity, the unit
requires favorable ambient conditions. However, since no two sites or installations are identical, this section takes
the form a generalized, site-or-application analysis, without focusing on the specific industries or applications
where the APM UPS may be utilized.
Also, since, as stated above, each site has its own characteristics, the following sections are intended purely as a
set of guidelines for the general procedures and practices that should be adopted by the personnel responsible
for installing the device. Ideally, the qualified engineers and technical personnel will have taken the time to study
and understand the applicable precautions and procedures, prior to analyzing the specific situation oat any given
site
2.1
Environmental Conditions & Requirements
This section covers the environmental conditions that must be satisfied in order to get the best out of the UPS
system. The environmental conditions should meet the requirements stated in the product technical
specifications, especially the ambient temperature, ventilation conditions, and cleanliness of the surroundings.
2.1.1
Selecting the UPS location
Prior to installation, it is essential to ensure that it is possible to guarantee the ambient conditions necessary in
order to obtain the best possible results in the selected location. The location of the UPS on site must be planned
and implemented by qualified professionals. The UPS should be positioned in a cool, dry, indoor environment with
adequate ventilation. Preferably, the area should be free from dirt, dust or debris, and the UPS should be placed
on a flat, non-flammable concrete surface. The environment should be free from conductive powders (such
metallic dust, sulfide, sulfur dioxide, graphite, carbon or conductive fibers, etc.), acid mist, or other any conductive
media (any strongly ionized substance). The environmental specifications should comply with the international
standards and specifications, within the pre-defined operating range, as displayed in the following table in Table

The UPS uses forced cooling by internal fans; cold air enters the UPS through the ventilation grills at the front of
the cabinet and exits the UPS through the ventilation grills at the back. Ventilation grills are important for cooling
the UPS and should not be blocked or obstructed. The rear of the UPS should be positioned at a minimum
distance of 500mm from the wall to avoid compromising UPS heat dissipation. This reduces the internal
temperature of the UPS and prolongs the life span of the system. As an addition, indoor extractor fans may be
installed to aid the flow of cooling air, thereby preventing a build up of temperature in the installation
environment. We also recommend using air filters, especially in the presence of dust and/or dirt in the
surrounding environment.
Note
When the battery is installed close to the UPS, the maximum permissible ambient temperature is dependent on
the battery and not the UPS
If the UPS is operating in Eco Mode, the power consumption will be less than the in Normal mode. An
appropriate air conditioner must be selected, depending on the normal operating mode.
2.1.2
Selecting the location of the Battery
Batteries generate quantities of hydrogen and oxygen as they reach the end of their discharge cycle; therefore,
