Hydran* 201i Instruction Manual 
 
8.3.5  Installing the AC Power Supply 
1.  The power supply cable of the Hydran 201Ci-C must be connected to an external 
circuit-breaker in accordance with local wiring regulations. 
The  circuit-breaker  must  be  located  in  close  proximity  to  the 
equipment and must be easily accessible. 
The circuit-breaker must be clearly identified with a label and 
marked as the disconnecting device for the equipment. 
2.  Run  the  three-wire  ac  power  supply  cable  through  a  conduit  up  to  the  Hydran 
201Ci-C. 
3.  Connect  the  cable to  the H201Ci-C’s L1/L  and  L2/N terminals,  and connect  the 
E/G wire to the enclosure chassis. For wiring details, see Table D - 8 in Appendix 
D. 
4.  Connect the other end of the cable to the power source.  
Note: The earth/ground terminal (E/G) must be connected. 
Never  perform  high-voltage  tests  (mega-ohm  measurements 
using a Megger* instrument) on cables connected to an H201Ti 
or a Hydran 201Ci Controller.  Never apply high voltages to the 
components  of  a  Hydran  201i  System,  as  they  are  equipped 
with  surge  protection  devices  that  could  be  damaged  by 
Megger* tests. 
 
8.3.6  Verifying the Operation 
Proceed as described in Section 8.2.1 and Section 8.2.2. 
 
8.3.7  Verifying the Supervisory Link Communications 
Verify communications between the Hydran 201Ci-C and the Hydran 201Ti(s) using a 
host computer running the Hydran Host software.  Proceed as described in Section 8.2.3 
and Section 7.2.9. 
 
8.3.8  Conclusion 
The installation of the Hydran 201Ci-C is now completed.
