Mounting Location of Hydran 201Ci Controllers
The following points pertain to all H201Ci Controllers (Hydran 201Ci-C and
Hydran 201Ci-1):
1.
All H201Ci Controllers are equipped with Type NEMA 4X enclosures and can thus
be installed outdoor.
2.
The H201Ci Controllers must be mounted on a vibration-free structure. If vibrations
are present, use vibration-absorbing rubber pads (Figure 1-5 on page 1-9), which can
be purchased from General Electric Canada.
3.
The enclosure must be placed at eye level.
4.
Allow enough space to open the door completely.
5.
Allow enough space to access easily the cable fittings under the enclosure.
6.
Good grounding of the enclosure and its supporting structure is essential to protect
the equipment against electromagnetic and radiofrequency interference.
7.
Install the enclosure as far as possible from circuit breakers or any other strong source
of radiofrequency noises. The enclosure can be installed up to 1,200 m (4,000 ft)
from the Hydran 201Ti. The total length of supervisory links (communication cable
between the H201Ci Controller and its H201Ti's) must not exceed 1,200 m (4,000 ft)
per H201Ci Controller.
8.
Dimensions for the H201Ci-C and H201Ci-1 enclosures are shown in Figure B-7 on
page B-5 and Figure B-8 on page B-6.
9.
The power supply source of the H201Ci Controller must be protected by an adequate
switch or circuit-breaking system as the means for disconnection:
• The switch or circuit-breaking system must be included in the building installation.
• It must be in close proximity to the equipment and within easy reach of the operator.
• It must be marked as the disconnecting device for the equipment.
