GENERAL ARRANGEMENT
In order to maintain the IP rating of the unit, the cable glands should be sealed to
the unit using a sealing washer (if possible) and sealing compound.
Once termination is complete, carefully push the cover back onto the unit, avoid-
ing damage to the seal. Tighten the 2
off cover screws evenly, to ensure correct
sealing.
3. OPERATION
The unit is powered directly. Different sound levels can be obtained by selecting
the transformer tappings in the unit.
4. MAINTENANCE
During the working life of the unit, little or no maintenance is required. However,
if abnormal or unusual environmental conditions occur due to plant damage or
accident etc., then visual inspection is recommended.
If a fault should occur, it is recommended that the unit be returned to MEDC for
repair. All parts are replaceable.
If you have acquired a significant quantity of units, it is recommended that spares
are also made available. Please discuss your requirements with the Technical
Sales Engineers at MEDC.
