7.2 - Power supply

The power supply must conform to the specication on the

chiller name plate. The supply voltage must be within the range

specied in the electrical data table.

For connections refer to the wiring diagrams.

WARNING: Operation of the chiller with an improper supply

voltage or excessive phase imbalance constitutes abuse which

will invalidate the Carrier warranty. If the phase imbalance

exceeds 2% for voltage, or 10% for current, contact your local

electricity supply source at once and ensure that the chiller is

not switched on until corrective measures have been taken.

NOTES:

The 30RA 040-240 units have only one power connection

point located at the main disconnect switch.

Before connecting electric power cables, it is imperative to

check the correct order of the 3 phases (L1 - L2 - L3).

Non-certied drawings. Refer to the certied drawings

supplied with the unit or available on request.

7.3 - Voltage phase imbalance (%)

100 x max. deviation from average voltage

Average voltage

Example:

On a 400 V - 3 ph - 50 Hz supply, the individual phase voltages

were measured to be:

AB = 406 V ; BC = 399 ; AC = 394 V

Average voltage = (406 + 399 + 394)/3 = 1199/3

= 399.7 say 400 V

Calculate the maximum deviation from the 400 V average:

(AB) = 406 - 400 = 6

(BC) = 400 - 399 = 1

(CA) = 400 - 394 = 6

The maximum deviation from the average is 6 V. The greatest

percentage deviation is:100 x 6/400 = 1.5 %

This is less than the permissible 2% and is therefore acceptable.
