Samsung DVM S Series - Electrical work cautions

66
Electrical wiring work
• This device is intended for the connection to a power supply system with a maximum permissible system
impedance shown in the table (on the left page) at the interface point (power service box) of the user’s supply.
• The user must ensure that this device is connected only to a power supply system which fullls the requirement
above. If necessary, the user can ask the public power supply company for the system impedance at the
interface point.
• This equipment complies with IEC 61000-3-12 provided that the short-circuit power Ssc is greater than or equal
to Ssc(*2) at the interface point between the user’s supply and the public system. It is the responsibility of the
installer or user of the equipment to ensure, by consultation with the distribution network operator if necessary,
that the equipment is connected only to a supply with a short-circuit power Ssc greater than or equal to Ssc(*2).

NOTE
Caution for electrical work
• You must install ELCB or MCCB + ELB
- ELCB: Earth leakage breaker
- MCCB: Molded case circuit breaker
- ELB: Earth leakage breaker
• Do not operate the outdoor unit before completing the refrigerant pipe work.
• Do not disconnect or change the cable inside the product. It may cause damage to the product.
• Specication of the power cable is selected based on following installation condition; culvert installation/
ambient temperature 30 °C/ single multi conductor cables. If the condition is dierent from the ones stated,
please consult an electrical installation expert and re-select the power cable.
- If the length of power cable exceed 50m, re-select the power cable considering the voltage drop.
• Use a power cable made out of incombustible material for the insulator (inner cover) and the sheath (outer
cover).
• Do not use the power cable with the core wire exposed due to insulator damage occurred during removal of the
sheath. When the core wire is exposed, it may cause re.
