PURPOSE AND SCOPE OF APPLICATION

Explosion-proof remote drive control panel PKIV-DPU01, PKIV-DPU02, PKIE-DPU01, PKIE-DPU02 is intended for control and indication of operation of an inverter with asynchronous electric drive in AC networks of electrical installations at chemical, gas, oil and other facilities, in areas with potentially explosive atmosphere.

Explosion-proof remote drive control panels are manufactured as per standard layouts and as per layouts determined by the customer. Additional visual indication is provided upon request for various processes by means of signal lamps and analogous pointer instruments that show rotation speed and/or torque.

Explosion-proof remote drive control panel is intended for operation with various inverters and frequency converters with analogous inputs and outputs of the devices.

Sign "Х", placed after Ex-marking of the device indicates that it is prohibited to use the device in explosive mixtures of acetylene with air.

Scope of application - underground mines and pits hazardous with gas (methane), coal dust; hazardous indoor and outdoor areas in accordance with explosion protection marking, GOST 30852.13-2002 (IEC 60079-14:1996) and areas hazardous with combustible dust ignition, as per GOST IEC 61241-3-2011, dangerous production facilities of I, II, III, IV hazard classes under supervision of Rostekhnadzor and national supervisory bodies of the CU and the CIS countries.

Typical layout:

PKIV-DPU01, PKIE-DPU01
(for 5 logical + 1 analogous inputs)

Forward / Stop / Reverse (switch)
