514C Product Manual
REQUIREMENTS FOR UL COMPLIANCE
UL and c-UL Listing applicable to 514C-04, 514C-08 and 514C-16 Series only.
Motor Overload Protection
An external motor overload protective device must be provided by the installer.
Motor over temperature sensing is required. Motors used in conjunction with the drive
controller shall be protected with PTC sensor(s) or relays suitable for use with the variable
speed drive. This combination cannot be evaluated by Underwriters Laboratories Inc., hence
it is the responsibility of the installer/local inspector determine whether the combination is in
compliance with the National Electrical Code NEC/NFPA-70, or local code requirements.
Technical details can be found in Chapter 3 Installing the Drive.
Field Grounding Terminals
The International Grounding Symbol
(IEC Publication 417, Symbol 5019) is used to
designate the field grounding terminals.
The field grounding terminal is a single screw, sized No. 10 (M5). UL Listed (ZMVV)
pressure wire connectors rated No. 14 AWG (copper) must be used for Models 514C-04,
514C-08. UL Listed (SMVV) pressure wire connectors rated No. 10 AWG (copper) must be
used for Models 514C-16.
Short Circuit Protection
UL Listed fuses, Class RK5, rated 250V ac or 600V ac (as appropriate, depending on the
rated input voltage of the drive), 50A maximum, must be installed upstream of the drive.
Short Circuit Rating
Models rated more than 1Hp. Suitable for use on a circuit capable of delivering not more than
5000 RMS Symmetrical Amperes, 480V maximum.
Operating Ambient Temperature
The maximum operating ambient temperature rating is 40
o
C.
Field Wiring Temperature Rating
Use 60
o
C or 60/75
o
C copper conductors only.
Field Wiring Terminal Markings
For terminal connections, refer to page 2-6, “Auxiliary Supply terminals”, “Power
Terminals”, “Field Terminals” and “Control Terminals” on page 2-2
Power Field Wiring Terminals
The pressure terminal connectors provided on models 514C-04, 514C-08 accept a maximum
copper conductor size of No. 14 AWG. The pressure terinal connectors provided on models
514C-16 accept a maximum copper conductor size of No. 10 AWG.
Terminal Tightening torque
Refer to page 3-4 “Terminal Tightening Torques” for the tightening torques for power,
control and grounding terminals.
