Installation, electrical

WARNING
• EX-pump only: Installations in potentially explosive atmospheres must be inspected by
a „accredited qualified" person. This applies in particular also for intrinsically safe
electrical circuits.
• EX-pump only: observe all relevant standards e.g. DIN EN 60079, DIN EN 50020 DIN
VDE 0165 and/or DIN VDE 0118 "Installing electrical equipment in explosion-threatened
areas"!
• EX-pump only: when installing the metering pump, observe the directives for the
installation of devices in explosion-threatened areas, e.g. for Europe the European
operator's guideline 99/92/EC (ATEX 137)*, (in Germany implemented via the new
operating safety ordinance (Official Federal Gazette for 2002, Part 1, No. 70, issued
in Bonn 2.10.2002))!
* previously ElexV
• EX-pump only: Read the documents provided for the individual electric components!

Motor

IMPORTANT
• Connect electric motor in accordance with VDE regulations as illustrated in the circuit
diagram provided.
• Check that the mains voltage and frequency agree with the values specified on the
motor ratings plate.
• Provide corresponding motor protection devices in order to protect the motor from
overload (e.g. motor protection switch with thermal overcurrent release).
Fuses are not motor protection devices!
• Drive motors must be secured by an appropriate motor protection switch. A motor
protection approved for this application must be used for Ex"e"-motors. (Protection
against heating due to overload)
• The specified rated motor output applies at a maximum ambient temperature of 40 °C
and installation altitudes below 1000 m above sea level.
The motor output will be reduced if these values are exceeded (refer to VDE 0530).
• Ensure unobstructed supply of cooling air!
• Installation in wet rooms or in the open:
S Arrange terminal box such that the cable lead-ins point downwards the bottom (can be taken
into account when ordering).
S Select PG screw glands suitable for the supply line, use reducer if necessary.
Seal cable lead-in well otherwise all other measures will be of little use.
S Apply sealing compound to PG screw glands and thread of dummy plugs, firmly tighten and
coat once again with sealing compound.
S Thoroughly clean sealing surfaces of terminal box and terminal box cover before re-installing.
Seals must be bonded on one side.
After a longer operating period, replace brittle seals by new ones.
Different types of motors are used depending on the application and required output.
ProMinent will send you the motor data sheets for the desired motor versions on request.
Motors for explosion-threatened workplaces
WARNING
• Motors in EX-areas must be installed and checked by persons with „recognised skills!
• Observe the operating manual supplied with the EX motor!
