3.4) Power supply connection.

DANGER. Risk of electrocution.
Connection and grounding are compulsory.
All electrical connections will be in accordance with the IEC-60364 Regulations (electrical installation in
buildings) or the regulations in force in the destination country and local regulations.
The power supply line of equipment must be adequately protected. These protection elements will
prevent damage to persons during an electrical leakage. An exclusive power supply line is
recommended.
The system protection will be based on an earth leakage switch (I∆n = 30 mA).
The electrical installation should have a multiple separation system with contact openings ≥ 3 mm.
The cabling procedures must be undertaken by a professional installation entity. Connection socket according
figure 5. Connections according diagrams 3.6. Voltage variations allowed ±15%.
1.- Mains terminal. See 3.6
2.- Earth terminal.
3.- External pressure switch control. See 3.7.
4.- RS 485 port.

3.5) Protections.

Equipment is protected face overcurrents, phase failures or short circuits by means of internal fuses.
Value of the fuses:
- For motors with nominal current > 10 A = 20 A (standard)
- For motors with nominal current < 10 A = calculate 2 x nominal current.
The fuses must be time-delayed, according to IEC 60127 standard.
