Preinstallation
location Considerations
Environment:
The unit is designed for indoor operation in ambient temperatures
of -40ºC (-40ºF) to +60ºC (+140ºF) with a relative humidity of 0% to 95% (non-
condensing).
supplemental Enclosures:
All units provided with terminal blocks must be
installed inside an enclosure and located so as to prevent accidental contact with
terminals during maintenance and service.
Electrical Connections
verify that all power circuits are de-energized and
locked out before making electrical connections.
All electrical connections must be installed by a licensed electrician. All wiring
must comply with the National Electrical Code (NEC) and applicable local codes.
voltage, Current and power Configurations
Before making connections to the unit, verify that
the unit model number and nameplate voltage rating
are appropriate for connection to the intended power
source.
Maximum Current Capability:
The total current draw that a unit may continu-
ously handle is provided in the Voltage, Current and Power Configurations table
on page 6.
notE:
Overloading the unit can permanently damage the device.
nominal voltage:
The nominal operating voltage for each model is provided in
the Voltage, Current and Power Configurations table on page 6.
notE:
Failure to use the unit at its rated voltage can permanently damage the
unit or provide inadequate protection.
grounding
Input and output ground terminals must be connected for proper operation.
Grounding is not only required for safety, but also for equipment performance.
Incorrect grounding can reduce or impede the operation of the unit.
