DLM-E 3kW & 4kW Series Power Supplies Installation
2.6 AC Input Power Connection
Before you can use the DLM–E system supply, you must determine your AC input power
requirements and connect an appropriate cable or line cord to the input connector. The power
supply is shipped with an input connector cover which you need to remove to make the input
power connections.
WARNING!
A device to disconnect the DLM–E supply from the energy supply source is
required. This switch or circuit breaker must be close to the DLM–E supply,
within easy reach of the operator, and clearly labeled as the disconnection
device for the DLM–E supply.

2. Maximum input current measured at low AC line and maximum output power.
3. The 3 kW DLM–E is designed to operate without derating to the output power level with either
a single–phase or three–phase AC input voltage without any internal jumper changes.
4. Single-phase AC inputs use L1 and L3 only. Improper connections will result in no output.
2.6.2 Input Line Impedance
The maximum input line impedance for operation at full rated output is 0.1 ohm. Higher source
impedance can be tolerated by raising the input line voltage or by reducing the power.
