2. When tightening the terminal screw connections, ensure the following tightening torques:
Terminal screw connection Tightening torque (Ncm)
M4 157 – 196
M5 196 – 245
3. Note that, for safety reasons, the earth conductor must be longer than the other cables in
case the cable slips out from the cable clamp.
4. Use separate cable grommets for power cords on the one hand and accessory cables on the
other, to avoid disturbances in control signals.
5. Fasten the power cord by using cable clamps/strain reliefs.
6. Bundle accessory cables together using cable binders.
6.8.1 Connecting power cord
6.8.1.1 Connecting the power cord to the indoor unit
The following method is applicable as appropriate for all indoor units, All in One units and hydrokits
of all generations, but will be explained here on the basis of the example of a hydrokit of the
H Generation (→ Installation example (Hydrokits), p. 177 ).
Carry out the following steps to connect the power cord to the indoor unit:
1. Open the indoor unit (→ 6.5 Opening devices, p. 155 ) and, if applicable, the connection
box.
2. Guide the cable through the cable gland ( 5 , a ) into the device.
3. Secure the cable by means of the cable clamps (strain reliefs) ( 3 , b ).
4. Connect the power cords 1 and 2 accordingly to mains connection 1 and 2 ( 1 , 2 ), according
to the installation example below (see below) and the connection diagram following it and
ensure that the earth conductor is longer than the other cables in every case (c).
5. Connect the connecting cable to the outdoor unit on the indoor unit terminal (4) and take
care to leave the earth conductor longer than the other cables (c). Also ensure that you
connect conductors of the same cable colour to the same terminal numbers on outdoor and
indoor unit.
6. Connect the other end of the power cord to the power grid via the disconnector which is
absolutely required in all cases.
7. Protect the individual power supply connections with a suitably sized fuse according to the
cable cross section and the maximum power consumption. Note that the contact clearance
between the poles must be a minimum of 3.0 mm.
