This equipment complies with EN/IEC 61000-3-12 provided that the short-circuit power Ssc is greater than or equal to YL34 :
3967.5kW, YL43 : 4657.5kW 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 YL34 : 3967.5kW, YL43 : 4657.5kW.

NOTE
1. Where ground work (earth) is carried out, do not connect the ground return to the gas pipe, water line pipe, grounded circuit of
the telephone and lightning rod, or ground circuit of other product in which earth leakage breaker is incorporated. (Such action is
prohibited by statute, etc.)
Make sure the indoor and outdoor connection wires are detangled and the lead wire should use the shortest routing to connect.
(There might be effect to received outside noise.)
2. Use the standard power supply cables for Europe (such as H05RN-F or H07RN-F which conforms to CENELEC (HAR) rating
specifications) or use the cables based on IEC standard. (245IEC57, 245IEC66)
3. Select the particular size of electrical wire for power supply cables in accordance with the standards of the given nation and
region.
