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.
9.4.2 Connecting the voltage and frequency changer (for chambers equipped with a volt-
age 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 battery test chamber with the voltage and frequency changer,
proceed in the following order:
1. Connect the battery test chamber to the connection socket (J) of the voltage and frequency changer
2. Establish the power connection of the voltage and frequency changer using the power cable (L)
3. Turn on the voltage and frequency changer at the power switch (K) (position “ON”)
4. Turn on the battery test chamber with the main power switch (13) in the lateral control panel
