Maintenance
Fuse Replacement
Two fuses are located on the left edge inside of the enclosure. The left fuse connects to
the internal battery, the right fuse connects to the charger/external power. The fuses are
2 amp, time-delay, speed-type fuses rated for 250 VAC. Replace as needed.
Enclosure Desiccant
It is extremely important to use a properly-sized desiccant for your deployment, and to
change desiccant before the entire volume has turned pink. Use enough desiccant
to effectively keep electronics dry until your next scheduled maintenance. Desiccant life
span is dependent on site conditions.
The enclosure contains one tube of desiccant that absorbs moisture as it enters the
enclosure through the vent tube. Keep the vent tube clear of obstructions. Replace as
needed. An additional desiccant pack may be located at the top of the enclosure.
Replace or dry as needed.
Lead-Acid Battery
The battery is a sealed, rechargeable, lead-acid 12V 7 Ahr battery. Replace the battery
every 18 to 24 months or if the voltage drops below 10 V to ensure maximum charging
capacity and to avoid unexpected power failures.
Remove the battery before short- or long-term storage or during transportation.
Cleaning
Clean the outside of the enclosure with a soft, damp cloth. Do not use ammonia or other
harsh chemicals.
