4 .8 .5 Redundant Power Module Replacement
AC Version
NOTE: The power cords for BOTH power modules must be disconnected before attempting to
remove the power modules or otherwise servicing the unit.
Power module failure will be indicated by the alarm being sounded and the green status light on the module will no longer be
lit. This power module may be replaced by fi rst disconnecting the AC power cord from the IEC input socket of BOTH power
modules, then release the module by pressing down on the thumb latch at the top of each module. Extract the module and
replace with an identical replacement module only.
DC Version
NOTE: The external disconnect for BOTH power modules must be turned off before attempting
to disconnect the DC wiring from the power module terminals or otherwise servicing the unit.
Power module failure will be indicated by the alarm being sounded and the green status light on the module will no longer be
lit. This power module may be replaced by fi rst disconnecting the DC power at the external disconnect device for BOTH power
modules then use a Phillips screw driver to remove the DC wires from the failed module terminals. Release the module by
pressing down on the thumb latch at the top of each module and extract the module. Replace with an identical replacement
module only.
4 .8 .6 Power Cord Protection
Measures must be taken during installation to route or arrange the power supply cords or wires to prevent physical damage
and to avoid the possibility of future damage occurring. The cords shall be installed and routed such that, throughout it’s
length, the cord and it’s points of connection are not strained in any way.
4 .8 .7 Power Cord Attachment
The unit AC power supply cords shall not be attached to a building surface, bundled with audio, video or RF coaxial cables,
nor run through walls, ceilings, fl oors and similar openings in the building structure.
4 .8 .8 Provision of Electrical Power Outlet
An AC electrical power outlet of appropriate type and rating shall be provided near the location where the unit is installed
and easily accessible such that the provided power supply cords may be routed in an appropriate manner, without the use of
extension cords, between the receptacle and the chassis. Alternately, the chassis shall be installed in close proximity to an
existing AC electrical outlet such that the requirements of this paragraph are achieved.
4 .8 .9 IEC Power Input Cord for AC
The AC power input receptacle is a standard IEC C13 connector similar to that commonly used on computers and monitors.
The power cords provided with the product is a North American confi guration with a NEMA 5-15 grounded plug for 115 VAC.
If it is necessary to operate the product on 230 VAC, the installer must obtain IEC cords with a NEMA 6-15 grounded plug for
use in North America. This may be obtained at time of order from ATX Networks or locally. If shipped outside of North America,
the encoder will be supplied with an IEC cord set appropriate for the locale to which it is shipped.
4 .8 .10 Input Power Requirements
When installing the equipment, it is the responsibility of the installer to determine that suffi cient capacity is available in the
electrical circuit feeding the unit to avoid overloading the supply circuit. The AC model will require power to be supplied from a
properly grounded AC outlet. The installer shall determine that the AC power outlet, its wiring and receptacle is in compliance
with local and/or national electrical codes as applicable. The AC input power requirement is constant over the range of input
voltages. At higher input voltages, the current consumption is lower than it is at lower voltages where the input current is higher.
4 .8 .11 Fusing
Internal over-current protection is built in to the power modules. There is no internal fuse to be replaced or maintained on either
the AC or DC versions. Each DC power supply, if installed, should be externally fused at no more that 10 Amperes.
