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.

Environmental Conditions

JDF300 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

WARNING

No repair is allowed in all JDF300 flameproof joints: threads

of enclosure, covers and plugs. Consult the manufacturer if

repair of the flameproof joint is necessary.

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.

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.
