Environmental Requirements
The following environmental conditions must be established and maintained to
ensure the safe and efficient operation and servicing of the GT100. Adequate
space must be provided around the unit for ventilation and access during
servicing. If locating the unit indoors, ambient air temperature cannot exceed the
maximum temperature for which the unit is rated. See Table A-1, “Environmental
Specifications” on page A–2.
•
Maintain a minimum clearance of 800 mm (31.5 in) in front and 305 mm (12
in) above of the GT100 Enclosure, plus local safety requirements for
maintenance and serviceability. The GT100 has a zero (0 mm) clearance
requirement at the rear and sides of the enclosure. Figure 2-3, “Conduit
Entries Above Ground, Multiple Views” on page 2–7.
•
External cabling interfacing with the GT100 may enter from either the bottom,
lower sides, or lower rear of the enclosure. The GT100 may be placed over a
foundation hole which holds the cables, or placed on top of a hollow platform
which allows access to the bottom of the GT100.
•
If the GT100 is to be installed indoors and external air is used for ventilation,
the required liter per minute (L/M) rate must be no less than 37,500 L/M
(1150 CFM). This assumes the temperature inside the building is allowed to
rise 10 °C (18 °F) above the outside temperature. Therefore, the maximum
allowable outside ambient temperature is 50 °C (50 °C minus 10 °C equals
40 °C Maximum Ambient Temperature) or 122 °F (122 °F minus 18 °F
equals 104 °F Maximum Ambient Temperature). Additionally for indoor
installations, the GT100 enclosure has provisions for an exhaust air duct to be
attached, by means of a 355 x 200 mm (14 x 8 in) opening at the top of the
enclosure. The GT100 enclosure rain hood must be removed in order to
access the exhaust openings.
If air conditioning is planned the heat load of the GT100 is 13,600 BTU/Hour
at full load.
