WARNING
Potential danger due to incorrect cables
An incorrect cable cross-section will cause the cable to overheat. Scorched insulation can cause fires.
 The cable cross-section (4) matches the output required for the power consumption and is
0.5 – 2.5mm² or AWG 20 to AWG 14.
The following general requirements must be ensured for safe and reliable operation of the cooling units:
• Upstream installation of a supply-side temperature regulator is prohibited.
• Connect the upstream fuse specified on the type plate as wiring protection; see Type plate and Adapting the
upstream fuse.
• Ensure that the type plate specifications for rated values match the present values for mains voltage and mains
frequency; see Type plate.
• Always connect the cooling unit to the mains by means of a separating device (switch/contactor).
 The separating device must have a contact opening of 3 mm. The separating device is installed by the
customer.
