IQ Power BPS
5201249 Rev. D
IQ Power BPS power supplies may also be manually re-addressed or reset to the
default address of “1”.
See Power Supply Number (Address / Device Number) section.
E.
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.
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.
Power supplied in the above fashion must have adequate current available to power
all components on the system (maximum 4A). Input power should be appropriately
fused for safety purposes.
See diagram for Power Supply Alarm Output Connections.
F.
Connect power supply alarm output
(if used). The power supply “Alarm Output”
is a standard DB25 pin connector located on the end of the IQ Power BPS
power supply. The power supply alarm output provides a variety of relay contact
outputs that echo the status of the power supply indicator lights. The relay
contacts are rated for a maximum of 1A at 30 VDC.
See Power Supply Alarm Output Connections diagram.
The alarm output connector also provides a means of remote power in. See section
“E. Connect user supplied power” for more details.
Remote on/off Control
. The “Alarm Output” connector also provides for remote on/
off control of the power supply. Remote on/off control is configured with a jumper
on a pin header on the main power supply circuit board. The default configuration
is with the remote control disabled. The remote control can be configured “normally
off” or “normally on” by the jumper setting. See Jumper Position at J3 for Remote
Control Operation diagram. To access the jumper the cover will have to be removed
from the power supply. Disconnect all input power from the power supply. Remove
the six screws securing the cover and slowly and carefully remove the cover.
