5 ELECTRICAL CIRCUIT

AVOID THE RISK OF THE ELECTROCUTION !!!

Only qualified 

persons should

 

attempt

 

installation, 

troubleshooting

, and

 repair. 

Ensure that power to the system is disconnected before removing covers to electrical boxes

.

IMPORTANT NOTE

To avoid possible electrical shocks that 

may

 cause 

injury

 or death, the 

Compact unit must be properly connected

to a safety ground

, as 

follows

:

1- Use a 

correctly sized

 

3-conductor 

electrical cable with ground wire section and isolation

.

2- Use only marine grade cable with multi-strand tinned conductors. Do not use residential wire with solid conductors

 

3-

 The ground wire must be correctly connected to the ground terminal of the panel.

4

- Check that the ground connection between the electrical box and the air-conditioner has

 not

 suffer

ed

 

from

da

mage during transport.

5

- Check that the

 ground

 connection of the water pump 

is securely and properly

 

connected in the 

electrical box

.

6

- Check the ground continuity

 with a multi-meter

 before switching off the air-conditioner.

WARNING

5.1 - 

Vega II, Vega III, and FX II Controls

All electrical connections are made inside the Power Module box

.

 See 

control 

Manual

s

 for specific details. 

5.2 - SUPPLY

Check that the available supply corresponds to the label on the unit, on the box and on the electrical pump.

Power should be supplied from a breaker of 

the 

correct rating

.

 See spec sheet for details.

All electrical wiring must be marine grade, of the correct gage, and with multi-strand tinned conductors

.

 

All connections on the terminal strip

s

 must be made with correctly sized 

wire and/or

 connectors
