3.5.4 Door contact switch
WARNING
Danger due to connection of external voltage at the input of the door contact
External voltage can cause severe accidents.
➢ Connection of external voltage to the input for the door cabinet is prohibited.
➢ The input/door contact provides low voltage (< 20V, 20mA) for the door contact switch.
Installation of a door contact switch increases safety and prevents increased accumulation of condensate.
 If a door contact switch has not been connected, the connection contact (S1) must always be bypassed.
Door contact switch installation
Requirements
- The cooling unit is de-energized.
Procedure
▪ The door contact switch is connected to the S1 connection; see
diagram in the housing cover.
▪ The door contact is supplied with low voltage, <20V, 20 mA, from the cooling unit.
▪ Connect the shielding to the terminal for functional earth on one end.
▪ A shielded cable with twisted pairs is used to prevent interference.
▪ If shielded cables are not used, ensure that there are no sources of interference in the immediate vicinity.
Sources of interference include supply cables and components with increased electromagnetic radiation,
including frequency converters, motor drives, etc.
 The door contact switch is connected. The motors switch off when the switch cabinet is opened.
