12 11 Requirements for installation and use in US and Canada
12.1 11.1 General
Important - Note for field indicator with combined approval. Before installation of the field indicator, the customer should permanent
mark his chosen Protection Concept on the safety label. The field indicator can only be used with according to this Protection Concept for
the whole life. If two or more types of protection box (on safety label) are permanent marked, the field indicator must be removed from
hazardous classified locations. The selected Type of Protection is allowed to be changed only by manufacturer after a new satisfactory
assessment.
12.2 11.2 Environmental Conditions
JDF200 is designed to be safe under the following conditions:
— Outdoor use
— Altitude up to 2000 m
— Mains supply voltage fluctuation up to ± 10% of the nominal voltage
— No temporary overvoltages occurring on the mains supply
— Pollution degree 2
— Maximum relative humidity 80 % for temperatures up to 31 °C decreasing linearly to 50 % relative humidity at 40 °C
— Transient overvoltages up to the levels of Overvoltage Category II
12.3 11.3 Entities
Nominal voltage drop 2,4 Vdc.
For ordinary location, it is necessary to use a fuse with If ≤ 400mA or current limiter. See table at paragraph 11.8 for reference.
12.4 11.4 Instructions for cleaning
Clean the external enclosure with soft rag and, if it is necessary, use mild cleaning solution and rains with clear water.
If deposits are expected to accumulate, the equipment should be cleaned on a regular basis, in accordance with the operating
conditions. Cleaning should ideally be carried out in a workshop.
12.5 11.5 Insulation for secondary circuits derived from MAINS CIRCUITS of OVERVOLTAGE CATEGORY II
up to 300 V
The power supply of the loop must be achieved by a transformer in which the primary windings are separated from the secondary
windings by REINFORCED INSULATION, DOUBLE INSULATION or a sceen connected to the PROTECTIVE CONDUCTOR
TERMINAL.
