American Magnetics 601 Energy Absorber (CE-Marked) - Manual (Page 3)

CAUTION: Current flow should be from the positive (+) to negative (
−
)
lug of the Model 601. If this is reversed, severe damage of the Model 601
will result.
NOTE: If an AMI Model 420 Power Supply Programmer is to be used
with the system, refer to the appropriate installation section in the
Model 420 Power Supply Programmer manual for a complete system
diagram and step-by-step instructions for all the system interconnects.
D. If you have purchased multiple Model 601 units with the Parallel Operation Option,
then up to five Model 601 units may be operated in parallel with a total current rating
of 90% of the sum of the ratings for each individual unit.
Typically, if multiple Model 601 units are to be connected, the positive (+) and negative
(
−
) lugs will be ganged together as illustrated below using a conductive plate. Simply
follow the installation directions in Step C above by treating each ganged lug as a
single output lug. The power leads, from the supply and to the magnet, may be
connected to any mounting lug if an additional lug is not provided in the ganged
conductive plate.
In addition to the ganged lugs, the coaxial connectors on the rear of each Model 601
must also be connected. If more than two units are connected in parallel, the middle
units may be connected to the coaxial cable by using standard BNC “T” adaptors. The
“end” units should be connected directly to the coaxial cable — no BNC “terminators”
should be used.
E. Supply power to the Model 601 by connecting the supplied external DC power
converter to the matching connector at the rear of the Model 601, and then connecting
the AC power cord to the appropriate power receptacle. The Model 601 is operational
immediately upon connection to a power receptacle.
WARNING: Do not position the external power supply or the Model 601
so that it is difficult to disconnect the power cords.
