2.3.2 Preparation
Mains connection of an energy back-feeding electronic load of ELR 9000 series is done via the included 5 pole
plug on the back of the device. Wiring of the plug is at least 3 strand or, for some models, 5 strand of suitable cross
section and length. For recommendations for cable cross section see “„2.3.4. Mains connection (AC)“.
Dimensioning of the DC wiring to the voltage source should also reect the following:
• The cable cross section should always be specied for at least the maximum current of the
device.
• Continuous operation at the approved limit generates heat which must be removed, as well as
voltage loss which depends on cable length and heating. To compensate for these the cable
cross section should be increased and the cable length reduced.
2.3.3 Installing the device
• Select the location for the device so that the connection to the source is as short as possible.
• Leave sufcient space behind the equipment, minimum 30cm, for ventilation of warm air that
will be exhausted even with devices which feed back up to 90% of the consumed energy.
A device in a 19” housing will usually be mounted on suitable rails and installed in 19” racks or cabinets. The depth
of the device and its weight must be taken into account. The handles on the front are for sliding in and out of the
cabinet. Slots on the front plate are provided for xing the device (xing screws not included).
On some models the mounting brackets provided to x the device in a 19” cabinet can be removed so that the
device can be operated on any at surface as a desk top device.
Acceptable and unacceptable installation positions:
Standing surface
