DC1 is designed to meet the UL requirements. In order to ensure full compliance, the following must be fully observed.
Input Power Supply Requirements
Supply Voltage
DC1-S1…
110 - 115 RMS Volt for 115 Volt rated units, ±10 % variation allowed. 115 Volt RMS Maximum
DC1-S2…
200 - 240 Volt for 230 Volt rated units, ±10 % variation allowed. 240 Volt RMS Maximum
Imbalance
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.

All the drives in the above table are suitable for use on a circuit capable of delivering not more than the above specified maximum
short-circuit Amperes symmetrical with the specified maximum supply voltage.
General Requirements
Mechanical Installation Requirements
All DC1 units are intended for indoor installation within controlled environments which meet the condition limits:
– for IP20 (NEMA 0) units, installation is required in a pollution degree 1 environment.
– for IP66 (NEMA 4X) units, installation in a pollution degree 2 environment is permissible.
Ambient temperature range
Operational
-10 °C to 50 °C (14 °F to 122 °F), to 60 °C (140 °F) with rerating (frost an condensation free)
Storage and Transportation
-40 °C to 60 °C (-40 °F to 140 °F)
Relative Humidity
< 95 % (non condensing). Drive must be Frost and moisture free at all times.
Max. altitude for rated operation
1000 m. Derate above 1000 m: 1 % / 100 m. Installation above 2000 m is not UL approved.
Electrical Installation Requirements
– For 1 phase supply, power must be connected to terminals L1/L and L2/N.
– For compliance with CE and C Tick EMC requirements, a symmetrical shielded motor cable is recommended.
– A fixed installation is required according to IEC 61800-5-1 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, EN 60204-1, Safety of Machinery).
– The cables must be dimensioned according to the local codes or regulations. Motor Cable: 75 °C (167 °F) Copper must be used.
– Suitable fuses to provide wiring protection of the input power cable should be installed in the incoming supply to the data shown in this Instruction Leaflet.
– The fuses must comply with any local codes or regulations in place. In general, type gG (IEC 60269) or UL Class J fuses are suitable.
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 MBCs 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.
– Transient surge suppression must be installed on the line side of this equipment and shall provide protection for a rated impulse withstand voltage peak of 4 kV.
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.
