HYBRID MOTOR STARTERS
DRMS Hybrid Motor Starters are intelligent and convenient solutions for controlling
3-phase asynchronous motors. These compact devices can provide up to 6 different
functions: Forward / Reverse, Soft Start / Soft Stop, Motor Overload Protection, and
Mains Isolating Relay.
Read all installation instructions before using the DRMS Hybrid Motor Starter and
refer to the product datasheet for more information.
For assistance, please contact Tech Support.

Important Considerations
Be sure to use input and output voltages within operating
ranges.
To achieve maximum ratings, there must be a minimum
spacing of 0.9 in (22 mm) between the devices in free air.
(See fig. 3)
For optimal thermal performance, motor starter should be
aligned vertically to maximize natural convection air flow.
Maximum surrounding air temperature is 60 °C (please see
derating curve). For maximum ratings the surrounding air
temperature should not exceed 40°C.

ADDITIONAL NOTES
• This device is intended for use on supply systems with a maximum voltage from phase
to ground of 300 V (e.g. for a three phase-four wire system 277/480 V or on a three
phase-three wire systems of 240 V), rated impulse withstand voltage of max. 4 kV.
• Suitable for use on a circuit capable of delivering not more than 5000 rms symmetrical
Amperes, 480 Volts maximum when protected by class CC, J or RK5 fuse rated
maximum 20 A.
• For use in pollution degree 2 Environment or equivalent.
• The control circuits of this device shall be supplied by an isolated 24 VDC power
supply which output is protected with a fuse rated max. 4 Adc.
• For installations according to Canadian National Standard C22.2 No. 14-13 (cUL Mark
only) and supply voltages above 400V:
- For 415 V max. supply voltage, transient surge suppression devices shall be installed
on the line side of this equipment and shall be rated 240 V (phase to ground), 415 V
(phase to phase), suitable for overvoltage category III, and shall provide protection for
a rated impulse withstand voltage peak of 4 kV.
- For 480 V max. supply voltage, transient surge suppression devices shall be installed
on the line side of this equipment and shall be rated 277 V (phase to ground), 480 V
(phase to phase), suitable for overvoltage category III, and shall provide protection for
a rated impulse withstand voltage peak of 4 kV.
• For reliable operation the 24 VDC auxiliary power supply needs to be fully stable
during the entire operation of the device. Removing this voltage while the output is
under load could cause permanent damage to the device.
