Check AC Line Voltage
The 6RL Series load can be ordered with one of two available 3-phase AC input voltage
configurations. Prior to connecting the DC load to the local mains, it is important to check
the type label on the unit to verify that its AC input configuration matches the local utility
power.
Note: Do not connect the electronic load to the mains if the AC input voltage,
phasing and frequency does not match.

Rear Panel Connections
All connections for input power and DC load input are made at the rear panel of the units.
The same applies to digital interfaces and Analog I/O. The rear panel also contains the Share
bus connectors. See reference image below.

Mains Supply
All APS 6RL models require 3 phase L-L voltage of either 208Vac L-L (Models numbers ending
in “-2”) or 380Vac~480Vac L-L (Models ending in “-4”) three-phase grid connection
depending on the model number. . The required mains plug is 4-pole, three phases plus
ground (PE). Following phases are required for the AC supply:
Nominal power
Supply from grid
Supply type
3100 W (1 unit)
L1+L2 or L2+L3 or L1+L3, PE
Three-phase, 208 V, L-L, 120° rotation angle
6200 W (1 unit)
L1, L2, L3, PE
Three-phase, 208 V, L-L, 120° rotation angle
9300 W (1 unit)
