• Prior to connection and start-up, check the power supply voltage. Compare the values to the specified
data located on the chamber’s type plate (left chamber side, bottom right-hand, chap. 1.6).
NOTICE
Danger of incorrect power supply voltage due to improper connection.
Damage to the chamber.
Check the power supply voltage before connection and start-up.
Compare the power supply voltage with the data indicated on the type plate.
• When connecting, please observe the regulations specified by the local electricity supply company
and as well as the VDE directives (for Germany). We recommend the use of a residual current circuit
breaker.
• Only use original connection cables from BINDER according to the above specification.
• Pollution degree (acc. to IEC 61010-1): 2
• Over-voltage category (acc. to IEC 61010-1): II
See also electrical data (chap. 25.4 and 25.5).
To completely separate the chamber from the power supply, you must disconnect the power
plug. Install the chamber in a way that the power plug is easily accessible and can be easily
pulled in case of danger.
4.8.2 Connecting the voltage and frequency changer (for chambers equipped with a
voltage and frequency changer)
The voltage and frequency changer is supplied with a fixed power connection cable without a plug. It is
protected against excess-current with 3 internal overload releases. The connection is made by the cus-
tomer.
The socket must provide a protective conductor.
Electrical connection data:
• Input side: 480 V, 60 Hz, 4-wire
• Output side (to the chamber): 400 V, 50 Hz, 5-wire
To establish the electrical connection of the alternating climate chamber with the voltage and frequency
changer, proceed in the following order:
1. Connect the chamber to the connection socket (G) of the voltage and frequency changer
2. Establish the power connection of the voltage and frequency changer using the power cable (I)
3. Turn on the voltage and frequency changer at the power switch (H) (position “ON”)
4. Turn on the chamber with the main power switch (3) in the lateral control panel
