2.3 Storage
Although well packaged, this equipment is not suitable for outdoor
storage. The equipment warranty will not be applicable if there is
evidence of outdoor storage. If the equipment is to be stored
indoors for any period of time, it should be stored with its protec-
tive packaging material in place. Protect the equipment at all
times from excessive moisture, construction dirt, corrosive condi-
tions, and other contaminants.
It is strongly suggested that the package-protected equipment be
stored in a climate-controlled environment with temperatures from
-30 to 85°C (-22 to 185°F) and with a relative humidity of 80%
or less. DO NOT, under any circumstance, stack other equipment
on top of a transfer switch equipment enclosure, whether pack-
aged or not.
Section 3: Equipment Description
3.1 General
The ATS consists of three basic panels:
1. The power panel;
2. The voltage selection and transformer panel; and
3. The microprocessor-based logic panel.
These panels are interconnected via connector plugs and mounted
in an enclosure (Figure 6).

3.2 Power Panel
The power panel is used for making load, power, and neutral con-
nections. The main contacts and the transfer mechanism are all
on one steel frame (Figures 7 and 8).
