3.3 Connection of Cables
3.3.1 Connecting the Power Cable (Use Accessory Pack Item: 3 Cable
Gland)
 Prior to connection, you must make sure that the external power source is
disconnected.
 Prior to connection, it is required to remove the cap from the power terminal of the
indoor unit and make sure that the cable is fastened before the cap is put back on.
 The power cable may be inserted from the top or from below.
WARNING:
1. The input power must conform to the rated value on the equipment nameplate.
2. In locking the screws for wiring at the power terminal block, use the
recommended installation torque (24kgf/cm
2
).
3. When installing the input power source, install the grounding line and confirm
that it is effectively connected first.
4. Follow the electricity system and local laws and regulations in the relevant
regions/countries, and select appropriate cable size(s).
5. Add a circuit breaker to the front of the equipment, in accordance with the
maximum power consumption indicated on the nameplate of the equipment
(recommended specifications: Branch Circuit Type Breaker, voltage tolerance
level of 300VAC/60A/3ports). In case of an overload or short circuit, this helps
protect other equipment of the loop.
6. If there is no wire passing through the communication wire duct at the top of
the cabinet, cover the duct with the cover plate provided in the accessory
package so as to avoid dust accumulation.
