Page 6: Introduction
1 Introduction Introduction The 370 DC Drive is a non-isolated speed controller for small brushed shunt wound or permanent magnet DC motors. This "non-isolated" drive has control signals that are NOT isolated from the mains supply, therefore, do not connect any of the terminals to earth or to other non-isolated equipment as when power is applied to the drive ALL terminals are at dangerous line potential. -

* Potentiometer, graduated dial and knob - Sprint Electric part number: POTKIT EMC wiring: If the unit is to be used in the domestic environment, then for installations in the EU a supply filter is recommended in order to comply with EN6800-3. Sprint Electric part number: FRLN16. - Page 11 WARNING! PERSONAL INJURY HAZARD Terminals A+, A-, F-, F+, N & L are at high potential. Do not touch the terminals or any connected conductor. RUN is an electronic inhibit function. The field remains energised, and all power terminals ‘live’. During hazardous operations remove the power source to the system.

7.3 Operating the drive WARNING! PERSONAL INJURY HAZARD RUN is an electronic inhibit function. The field remains energised, and all power terminals ‘live’. During hazardous operations remove the power source to the system. RUN must not be relied on to ensure the machine is stationary. The motor FIELD output remains energised with RUN open, please beware of overheating the motor when stopped - this does not apply to permanent magnet motors. -
