4. Refer to Battery Installation and Replacement
Procedures on page 3-1 for installation of a new
battery.
5. Reinstall the access cover plate on the top face of
the Master Module.
Disposal of Discharged Lithium Batteries
In the United States, transportation of depleted
lithium batteries for disposal is controlled by the
Code of Federal Regulations, Title 49. Depleted
lithium batteries are defined by the extent that the
open circuit voltage is less than the lower of:
•
2.0 volts or
•
Two-thirds of the voltage of a fully charged
battery
Check the Code of Federal Regulations, Title 49 or
local regulations regarding the current methods and
procedures for the disposal of lithium batteries.
Calibration
The calibration interval for the Powermonitor II
depends on the user’s accuracy requirements. To
meet general operating requirements, regular
recalibration is not necessary.
Contact your nearest Allen-Bradley Sales Office for
calibration or service information.
Cleaning Instructions
1. Turn off all electrical power supplied to the
Master Module and Display Module.
2. Clean the Master Module with a dry, anti-static,
lint-free cloth. Remove all dust and any
obstructions from the cooling air vents on the
upper, lower, and ends of the module. Ensure that
the nameplate is clean and in good condition.
3. Clean the Display Module with a dry, anti-static,
lint-free cloth. Remove all dust and any foreign
material(s) from the exterior of the module.
Ensure that the graphic front panel overlay and
back nameplate are clean and in good condition.
Field Service Considerations
If the Powermonitor II requires servicing, please
contact your nearest Allen-Bradley Sales Office. To
minimize your inconvenience, the initial installation
should be performed in a manner which makes
removal easy.
1. A CT shorting block should be provided to allow
the Powermonitor II Master Module current
inputs to be disconnected without open circuiting
the user supplied CTs. The shorting block should
be wired to prevent any effect on the external
protective relays.
2. All wiring should be routed to allow easy
maintenance at connections to the Powermonitor
II terminal strips, the Powermonitor II rear cover,
and the Powermonitor II itself.
!
ATTENTION: The battery is held
under pressure within its holder and
may be forcefully ejected upon
extraction.
!
ATTENTION:
•
Disconnect and lock out all power sources
and short all current transformer secondaries
before servicing. Failure to comply with these
precautions can lead to personal injury or
death, property damage or economic loss.
•
Please follow appropriate Electrostatic
Sensitive Discharge (ESD) procedures during
cleaning.
!
ATTENTION: A CT circuit must not
be opened with primary current present.
Wiring between the CTs should include
a terminal block for shorting the CTs.
Open CT secondaries will produce
hazardous voltages, which can lead to
personal injury or death, property
damage, economic loss, or CT failure.
