IQ Power™ BPS
5201197 Rev. D
Where the Control Station does not supply 24 VDC power to the BPS, the BPS will
require its own AC adapter. In this case, plug the modular cable into one of the four
connectors numbered 1 thru 4 and labeled “COMM ONLY” on the Control Station.
See diagram for Power Supply and Control Station Connections.
The modular cable should not be run parallel with the static bar high voltage cable.
Route the modular cable clear of moving machine parts and protect it from abrasion.
Secure using nylon wire ties (not supplied). Do not over tighten wire tie.
If there is an excess of modular cable, do not coil it in the vicinity of the static bar
high voltage cable. If possible, cut modular cable to length and re-term inate using an
RJ-4S connector installed with the same “polarization” as connector removed (note
rib / wire color code to modular connector).
If multiple 10 Power BPS power supplies are connected to the Control Station, each
power supply must be given a unique address. This is necessary to enable reliable
digital communication. The power supplies should each be given a unique address
prior to connection with the Control Station . See section 6.3 Power Supply Number
(address) for details on re-addressing the power supplies.

Connect user supplied power
(if used). In cases where the user does not want to use
the AC adapter but wants to supply 24 VDC power to the IQ Power™ system, user
supplied 24 VDC power may be applied two ways.
The “Power In” connector on the end panel of the IQ Power™ BPS may be used to
supply power to the system. This connector requires the use of a Switchcraft 760K
barrel type power plug. The plug should be wired +24 VDC to center and common
(ground) to outer barrel. The common must be bonded to electrical ground. Wired
in this fashion, the “Power” switch on the end panel of the power supply is in circuit.
Where a communication module is used, power will also have to be supplied through
the “Power In” connector on the end panel of the communication module.
The “Alarm Output” connector on the end panel of the IQ Power™ BPS may be used
to supply power to the system. This connector requires the use of a standard DB25
connector. The connector should be wired:
• +24 VDC to pins 13 & 25
• Common (ground) to pins 12 & 24
To ensure current carrying capacity, two pins are used for each connection. The
common must be bonded to ground. Wired in this fashion, the “Power” switch on
the end panel of the power supply is bypassed. See Power Supply Alarm Output
Connections illustration.
Power supplied in the above fashion must have adequate current available to power
all components on the system (power supplies: maximum 4A, communication
modules: maximum 1A). Input power should be appropriately fused for safety
purposes.
