Insulation thickness

Take the following into account when determining the insulation

thickness:

Depending on your local weather conditions, you may need to

increase the thickness of the insulation. If the ambient temperature

exceeds 30°C and the humidity exceeds 80%.

▪ Increase the thickness of the liquid piping with ≥5 mm.

▪ Increase the thickness of the gas piping with ≥20 mm.

Insulation sealing

To prevent rain and condensed water entering the unit, add a

sealing between the insulation and the front panel of the unit.

DANGER: RISK OF ELECTROCUTION

WARNING

ALWAYS use multicore cable for power supply cables.

NOTICE

The distance between the high voltage and low voltage

cables should be at least 50 mm.

About electrical compliance

This equipment (LRYEN10A7Y1 and LRNUN5A7Y1) complies with:

▪ EN/IEC 61000‑3‑11 provided that the system impedance Z

less than or equal to Z

at the interface point between the user's

max

supply and the public system.

▪ EN/IEC

61000‑3‑11

Standard setting the limits for voltage changes, voltage

fluctuations and flicker in public low-voltage supply systems for

equipment with rated current ≤75 A.

▪ 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 system impedance Z
