GB INSTALLATION
3. Before installation
3.1. Mechanical specifi cations required
If the wall is thin (hollow bricks or similar), use the backplate (part no. 99930887) to be mounted on the wall or placed on the side of the wall opposite
the wall where the unit is to be installed.
Decide on a suitable system for fi xing the plate according to the characteristics of the wall and its ability to resist a pull force of 220 Kg applied at
each anchorage point.
If the wall is made of cement or solid bricks, use the wall plugs supplied.
Alternatively we recommend using the “FISHER” chemical wall plugs which include:
• Braid type injection insert (item FIP 16X85).
• Threaded bar with bar and washer (item FIP 16M, 8X110).
• Chemical fi xer (item FIP C 150).
3.2. Central control unit power supply
The supply line running to the central control unit must be 3x2.5 mm and protected by a bipolar circuit breaker which conforms to the relevant electrical
codes (10 A, 250 V, breaking power at least 6000 A, distance between contacts at least 3 mm).
The colour of the three conductors (LINE, NEUTRAL and GROUND) must correspond to that established by regulations.
3.3. wiring connection between central control unit and generator light
This connection enables the generator light (optional) located outside the surgery to be turned on.
To connect the LP generator light to the central control unit, use 2 conductors having a cross-section of 0.5 mm (see paragraph 4.8.).
LP light supply: 230V - 3x2.5 mm line.
