Electrical connections

Be sure to observe all relevant safety regulations during the electrical installation of the pump. The
main power supply must be turned off before connecting the pump.
Danger
Warning
Note
Install a device to disconnect the pump motor from all poles of the main power supply according
to EN 60335-1.
The pump needs to be installed in such a way, that contact to parts carrying live voltage (e.g.
electrical connections) is impossible.
For wiring the cables and wires, please follow these steps:
Unscrew and remove the lid of the connection box.
Lead connection cable
[approx. 0.2
connection box lid.
Keep the inside of the junction box clean.
Close lid of the junction box. Please make sure that the lid does close correctly, and the sealing
of the box is still in good condition.

Do not operate bellows pumps MP F.. in explosive environments!
Incorrect voltage can destroy the device.
When connecting the equipment, please ensure that the supply voltage is
identical with the information provided on the model type plate. The supply
voltage is only allowed to deviate max. ±5 % and frequency ±2 % from the
indication on the model type plate.
Exceeding the tolerance increases the heating and influences the electro-
magnetic compatibility (EMC).
The air-cooled motor is designed for an ambient range +10 °C to +50 °C /
0 °C to +50 °C for dry sample gas (+50 °F to + 122 °F / +32 °F to + 122 °F
for dry sample gas) and an installation altitude of < 1000 m (< 3281 ft.)
above sea level.
The installation and commissioning of the device must conform to the re-
with Nominal Voltages below 1000
relevant regulations and standards!
The current supply circuit of pump type MP-F... (230 V) has to be provided
with a motor circuit braker 0.3 A corresponding to the rated current (over-
current protection).
The current supply circuit of pump type MP-F... (115 V) has to be provided
with a motor circuit braker 0.57 A corresponding to the rated current (over-
current protection).
