Additional Information for UL
￫ Refer to Manual MN04020003Z-EN and MN040023EN.
DC1 is designed to meet the UL requirements. In order to ensure full compliance, the following must be fully observed.

Short Circuit Capacity
Incoming power supply connection
– For 1 phase supply, power should be connected to L1/2 and L2/N.
– For 3 phase supplies, power should be connected to L1, L2, and L3. Phase sequence is not important.
– For compliance with CE and C Tick EMC requirements, a symmetrical shielded cable is recommended.
– A fixed installation is required according to IEC61800-5-1 with a suitable disconnecting device installed between the DC1 and the AC Power Source.
The disconnecting device must conform to the local safety code/regulations (e. g. within Europe, EN60204-1, Safety of machinery).
– The cables should be dimensioned according to any local codes or regulations. Guideline dimensions are given on page 6.
– Suitable fuses to provide wiring protection of the input power cable should be installed in the incoming supply line, according to the data on page 6.
The fuses must comply with any local codes or regulations in place. In general, type gG (IEC 60269) or UL Class CC or Class J fuses are suitable; however in some
cases type aR fuses may be required. The operating time of the fuses must be below 0.5 seconds. The max. voltage rating for fuses is 600 V.
– Where allowed by local regulations, suitably dimensioned type B MCB circuit breakers of equivalent rating may be utilised in place of fuses, providing that the
clearing capacity is sufficient for the installation. The max. voltage rating for breakers is 480 V.
– When the power supply is removed from the drive, a minimum of 30 seconds should be allowed before re-applying the power.
A minimum of 5 minutes should be allowed before removing the terminal covers or connection.
– The maximum permissible short circuit current at the DC1 Power terminals as defined in IEC60439-1 is 100 kA.
– An optional Input Choke is recommended to be installed in the supply line for drives where any of the following conditions occur:
– The incoming supply impedance is low or the fault level/short circuit current is high.
– The supply is prone to dips or brown outs.
– An imbalance exists on the supply (3 phase drives).
– In all other installations, an input choke is recommended to ensure protection of the drive against power supply faults.
All DC1 units are intended for indoor installation within controlled environments which meet the condition limits.
Ambient temperature range
Max. altitude for rated operation
Relative Humidity
Branch circuit protection must be installed according to the relevant national codes. Fuse ratings and types are shown on page 6.
Suitable Power and motor cables should be selected according to the data.
Power cable connections and tightening torques are shown on page 6.
Only a single conductor type is allowed in each field wiring terminal when
connected in group installation arrangement.
Motor Overload Protection
DC1 provides motor overload protection in accordance with the National Electrical Code (US).
– Where a motor thermistor is not fitted, or not utilised, Thermal Overload Memory Retention must be enabled by setting P-51 = 0
Set the parameters P1-08 „Current Limit" on motor current.
– Where a motor thermistor is fitted and connected to the drive, connection must be carried out according to the information, refer to Manual.
– Ratings shown above apply to 50 °C (122 °F) Ambient temperature. For derating information, refer to Manual.
￫
– The maximum motor cable length stated applies to using a shielded motor cable. When using an unshielded cable, the maximum cable length limit may be
increased by 50 %. When using the Eaton Drives recommended output choke, the maximum cable length may be increased by 100 %
– The PWM output switching from any inverter when used with a long motor cable length can cause an increase in the voltage at the motor terminals,
depending on the motor cable length and inductance. The rise time and peak voltage can affect the service life of the motor.
Eaton Drives recommend using an output choke for motor cable lengths of 50 m or more to ensure good motor service life
– For UL compliant installation, use Copper wire with a minimum insulation temperature rating of 75 °C (167 °F), UL Class CC or Class J fuses.

200 - 240 RMS Volts for 230 Volt rated units, ±10 % variation allowed. 240 Volt RMS Maximum
380 - 480 Volts for 400 Volt rated units, ±10 % variation allowed, Maximum 500 Volts RMS
Maximum 3 % voltage variation between phase – phase voltages allowed
All DC1 units have phase imbalance monitoring. A phase imbalance of > 3 % will result in the drive tripping.
For input supplies which have supply imbalance greater than 3 % Eaton Drives recommends the installation of input line reactors.
