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.
DANGER
Electric arcing can cause electric shock and burns.
When disconnecting and connecting the plug connector for mains connection under load or voltage,
electric arcing, dangerous voltage and electric shock can occur.
 The plug connector for mains connection must never be plugged in or disconnected under
load/voltage.
 Work on plug connectors must only be carried out with adequate lighting.
 Always switch off the circuit breaker and secure against reconnection.
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
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
