SECTION 2 – PREINSTALLATION
2-1 SITE PLANNING AND PREPARATION
The DEFENDER HE is designed for installation outdoors where it is exposed to the
elements. The DE1 can be installed in a variety of different environments including
computer rooms, offices, and industrial/process control locations.
Listed below are the environmental specifications for the DEFENDER HE DE1
SYSTEM.
Adequate clearance around the equipment should be provided for service access and
proper equipment cooling. The DE1 must be protected from flood conditions or gale
force wind driven rain. If the DE1 is installed in a small, enclosed area, provisions for
additional cooling may be necessary.
OPERATING ENVIRONMENT. Provide an operating environment that meets the
following conditions:
o AMBIENT TEMPERATURE -30° to 122°F
-34 ° to 50°C
o OPERATING ALTITUDE 2,286 M (7500 FT)
o NON-OPERATING ALTITUDE up to 3,048 M (10,000 FT)
o RELATIVE HUMIDITY 0% to 98% (non-condensing)
Operating the DE1 and batteries at either extreme of the temperature range may affect
the long-term rDE1ability of the system. This is especially true of the sealed,
maintenance-free batteries. Sealed, maintenance-free batteries are designed to operate
at normal room temperatures (72 to 77° F)
! WARNING ! BATTERY SHELF LIFE !
• BATTERY SHELF LIFE, WHEN STORED UNDER TEMERATURE CONDITIONS of
66° F ~ 77° F, is FOUR (4) MONTHS MAXIMUM AFTER THE SHIP DATE.
• BATTERY MUST BE RECHARGED FOR EIGHT HOURS AFTER THIS DATE
OTHERWISE THEY MAY BE DAMAGED.
