- The panel should be painted with a light gray rust-

resistant electrostatic powder painting.

- The panel should be firmly locked and weather-

proof with a degree of protection "IP54" or "IP41"

high operating temperatures.

- The capacitor and its components should have the

following technical data: -

Design voltage (Un): 525 Volt

Operating voltage: 400 Volt

Frequency: 50 Hz

4. Standards:

In addition to the specifications above, all the distribution panel components should comply with the relevant latest applicable standards issued by the IEC 61439 -1 & IEC 60947

5. Marking:

The marking (labeling) of the distribution panel

components should be on a name plate as shown: -

Manufacturer Name:

Manufacturing Year:

Serial No.:

Panel current:

P.O No. /Year

Customer: ..… EDC

6. Inspection and Testing:

1) …EDC preserves its rights to witness the routine

testing of distribution panel.

2) Unless otherwise specified or approved in writing by

(…EDC) all distribution panel should be tested under

all relevant latest applicable IEC standards.

3) Routine tests of all components should be carried out

according to the latest IEC standards by the

manufacturer at his lab or any certified and approved

lab and on his charge.

4) All test certificates and the approval certification

should be provided.

5) A copy of the type test certificate for the circuit-

breakers and capacitors of the panel will be delivered to

(…EDC) from "High voltage research center"

according to IEC.

6) Attendance of (…EDC) inspection engineers during

fabrication stages and testing should not relieve the

manufacturer from his full responsibility for

manufacturing the distribution panels under the

requirements of this specification and should not give

him the right to invalidate any claim that (…. EDC)

may make because of defective or unsatisfactory

material or faulty workmanship.
