Checking Correct Grounding - Samsung ACC2400C Owner's Instructions & Installation Manual

Checking Correct Grounding

If the power distribution circuit does not have an earth or the ground does
not comply with specifications, an grounding electrode must be installed.
The corresponding accessories are NOT supplied with the air conditioner.
1 Select an grounding electrode that complies with the specifications given
in the illustration.
2 Determine a suitable location for the grounding electrode:
In damp hard soil rather than loose sandy or gravel soil that has a
higher grounding resistance
Away from underground structures or facilities, such as gas pipes,
water pipes, telephone lines and underground cables
At least two metres away from a lightening conductor grounding
electrode and its cable
N o t e The grounding wire for the telephone line cannot be used
N o t e
to ground the air conditioner.
3 Finish wrapping insulating tape around the rest of the pipes leading to the
outdoor unit.
4 Install a green/yellow coloured grounding wire (Ø1.6 mm/ ", section
3
2 mm / in or greater):

If the grounding wire is too short, connect an extension lead, in a
mechanical way and wrapping it with insulating tape (do not bury the
connection)
Secure the grounding wire in position with staples
N o t e If the grounding electrode is installed in an area of heavy
N o t e
traffic, its wire must be connected securely.
5 Carefully check the installation, by measuring the grounding resistance
with an ground resistance tester. If the resistance is above required level,
drive the electrode deeper into the ground or increase the number of
grounding electrodes.
6 Connect the grounding wire to the electrical component box inside of the
outdoor unit.
