7. ELECTRICAL CONNECTION
Caution: Risk of electrical shock!
Hazardous electrical voltage.
All work related to electrical installation to be performed by expert staff (electricians or expert personnel with equivalent
training) only. Do not connect the reverse osmosis unit to the live power supply before all installation work has been
completed.
The customer is responsible for checking expert staff qualification.
General installation rules
• All local rules concerning the implementation of electrical installations must be obeyed.
• Electric connector cables to be laid professional.
Notice: Possible electronical components destruction through electrostatical discharge!
Prior to commencing electrical installation work, steps must be taken to guard the sensitive electronical components of
the unit control against damage from electrostatical discharge.
7.1 Procedure for electrical installation
Insert the plug into a suitable socket. The performance values are given in the technical data.
No further wiring is required. Exceptions:
• Connection of the internal alarm output to an external alarm detector
• Connection of a dosing pump (ROC140)
Fuses
CAREL recommends the use of main fuses with slow-to medium-load characteristic.
The reverse osmosis system should be operated by its own residual current circuit breaker.
7.2 Electrical installation check list
Check electrical installation with respect to customer-site requirements and local power supply regulations.
• Supply voltage in accordance with name plate voltage rating?
• Have all electrical cable and plug connections been properly tightened?
