8. Undo and remove the four screws (3) which secure the cover (2) to the HCMB pump-motor
terminal-box, then remove the cover (through the access hole in the rear cover-plate).
9. Look at the links in the terminal-box (8):
•
For high voltage operation (380-415 V at 50 Hz or 460 V at 60 Hz), ensure that the links (9)
are in the positions shown in detail C.
•
For low voltage operation (200-208 V at 50 Hz or 200-230 V at 60 Hz), ensure that the links
(9) are in the positions shown in detail D.
10. Refit the cover (2) to the pump-motor terminal-box and secure with the four screws (3).
11. Refit the Electrics Box (6) to the rear of the iH system and secure with the four screws (7):
ensure that you do not trap any of the cables connected to the Electrics Box.
3.16.3 Connect the electrical supply to the iH system
WARNING
This equipment is suitable for Installation Category 2 as defined in IEC 664
(EN61010-1). Connect the iH system to the electrical supply through a
suitably rated isolator/contactor for your iH system (refer to Section 2 and the
Notes below).
WARNING
Ensure that the iH system and your electrical supply cable are suitably
protected against earth (ground) faults and that the earth (ground) conductor
of the electrical supply cable is longer than the phase conductors in the
connector. On an iH1000 system, you must fit a second protective earth
(ground) conductor (with a cross-section of at least 10 mm
2
) to the protective
earth (ground)stud on the Electrics Box
CAUTION
This is an industrial (class A) product as defined by EN 61326. To ensure compliance with
European Electromagnetic Compatibility (EMC) requirements for harmonics and flicker,
please note that it is not intended for use in domestic buildings, or in properties directly
connected to a electricity supply network which also supplies domestic buildings.
