Connections; Initial Start-Up - Nederman L-PAK Serie Manual De Instrucciones

EN L-PAK 150, L-PAK 250
The settings for the motor's overcurrent relay are stated in the column S1F.
The settings for the overload relay are set when the unit is tested before
delivery, but should be verified when installing the unit.
For L-PAK the setting is the same as the nominal current of the motor.
The transformer is a multi- transformer with terminals for several different
supply voltages, indicated on top of the transformer. Ensure the connection
matches the actual supply voltage. The secondary voltage is always 24 V DC.

Initial Start-up

NOTE! The expression "automatic start/stop" in the following text means both
automatic idling and automatic start/stop.
The unit with options is tested before delivery and all functions are checked.
Check before starting for the first time that:
• The switch-disconnector is installed.
• The unit room, if small, has ventilation openings. See Site.
• The plastic sack is in place in the collector bin. The unit should not be
used without a plastic sack!
• The pipe work is connected to the dust collector inlet.
• An exhaust air duct is attached to the outlet to lead away hot exhaust air.
WARNING!
Never run the unit without an exhaust air duct. An incorrectly installed/
positioned exhaust air duct can cause personal injury. The exhaust air/exhaust
air duct can reach high temperatures.
• The compressed air supply is permanently connected. Filter cleaning,
