ELR/ELM 5000 Series
2.3.2 AC connection
Mains connection of an energy back-feeding electronic load rack of ELR 5000 series is done via the included socket
(250 V, 16 A) on the back of the device. A suitable mains cord is included in the delivery.
2.3.3 Installing the rack
• 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30cm,forventilationofwarmairthat

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).

2.3.4 Installing load modules
Beforeinstallinganynumberofloadmodulesthersttimeorbeforeremovingmodulesorchangingthecongura-
tion, notice following:
• Always switch off the rack with the power switch and if possible, remove mains cord
• Remove voltage sources from DC input of all load modules about to be inserted/removed
• In case the rack was operating shortly before it has been switched off in order to insert/remove
modules, wait at least 30 seconds before proceeding to the next action
• Never insert any module while the rack is switched on! If you are not sure whether the indica-
tion on the power switch is right, disconnect mains cord.
2.3.4.1 Inserting modules
The modules are intended to be inserted from left to right, because one module is the guide for next one. With this
intention in mind, the modules could be numbered with position 1 (left) to 5 (right). When going to install a module
inposition4whiletheoneforposition3isnotyetinstalled,itwillbemoredifculttondthecorrectposition.But
the installation is possible anyway.
Proceed as follows:
1. Insert the module at the desired position and push it into the rack so that it stands out for approx. 2 cm. Upper
or lower row, as desired.
2. Pushthemoduletotheleft,untilitndsstopattherackguidance(position1)orthemoduletotheleft.
3. Pushthemoduleintotherackuntilfullstop.Youshouldnoticeashorttactileresistancebeforeitnallyrests.
4. Fix the module on the front plate with four of the included screws (M2.5x8, metric thread).
5. Continue the same way with further modules, if required.
