Cleaning the enclosures
The Power Cabinet and Charge Post are powder coated. This coating must be kept in good condition.
The customer facing charge post is coated in RAL 9003, which is a fresh bright white. It gives a mod-
ern appearance and matches well with branding stickers in all kinds of colors. RAL 9003 (signal white)
is also used in Terra 53. RAL 9003 needs periodic cleaning to remove dirt. To limit maintenance costs
the power cabinet’s default color is RAL 9002 (grey white) on which dirt is less visible.
Clean the Power Cabinet and Charge Post at least three times a year in the following way:
•
Remove rough dirt by spraying with low-pressure tap water.
•
Apply a neutral or weak alkaline cleaning solution and let it soak.
•
Remove dirt by hand with a non-woven nylon hand pad.
•
Rinse thoroughly with tap water.
•
Optionally, apply wax on the front for extra protection and gloss.
•
Check the coating for damage.
NOTICE
Ordinary cleaning
Keep the air inlets clean and free from snow and leaves or from any other materials.
NOTICE
Rust forming
When the charger is placed in a corrosion sensitive environment, the form-
ing of superficial rust is possible on the welding points. This rust is merely
visual, there is no risk for the cabinet’s integrity. The rust can be removed
with the cleaning procedure described above. To prevent the rust from re-
appearing; prime the areas with a transparent or color-like priming finish
(separate Service Instructions are available).
NOTICE
When the Terra HP Charger is exposed to rain, it is sufficient to clean it twice
a year.
CAUTION
Do not apply high-pressure water jets. Water may leak into the Power Cabi-
net. If a high-pressure water jet has been used, make sure that the inside of
the Power Cabinet is dry.
- Only use cleaning agents with a pH value between 6 and 8.
- Do not use cleaning agents with abrasive components.
- Do not use abrasive tools.
