Page 17: Packaging, Transport And Storage
4 Packaging, transport and storage 4.1 Purpose The packaging is designed to protect the packaged product during transport, loading, unloading and during periods of storage in such a way that no detri- mental changes occur. The packaging must protect the goods against per- mitted transport stresses such as vibration and knocks. -
Page 18: Transportation, Receipt And Handling Of Shipments
4.4 Transportation, receipt and handling of shipments In addition to vibrations, jolts must also be expected during transportation. In order to prevent possible damage, avoid dropping, tipping, knocking over and colliding with the product. If the packaging tips over or falls, damage is to be expected regardless of the weight. -
Page 19: Storage Of Shipments
Hidden damage When damage is not determined until unpacking after receipt of the ship- ment (hidden damage), proceed as follows: – Make the party responsible for the damage liable as soon as possible by telephone and in writing, and prepare a damage report. –... -
Page 20: Mounting
5 Mounting This chapter describes how to correctly mount and connect the device. The pressure relief device is mounted on a device flange on the transformer or on-load tap-changer. Note the connection diagrams provided. DANGER Electric shock! Risk of fatal injury due to electrical voltage. Always observe the following safety regulations when working in or on electrical equipment. -
Page 21: Checking The Pipe Flanges
CAUTION Risk of injury and damage to property! Escaping hot oil and gas can lead to injuries and damage to the device. Direct escaping hot oil and gas away from people and critical transformer parts. The pressure relief device can be mounted horizontally or vertically, as close as possible to potential error sources. - Page 22 NOTICE! A residual distance between the flanges caused by a deviation in evenness can cause damage to the flanges.Even slight unevenness can cause the flange of the device to be curved too much, leading to cracks in the flange caused by the resulting transverse stress. Therefore, check the following: –...

Page 23: Mounting The Device
5.2 Mounting the device You must first remove the protective cover to mount the device. After mounting, reattach the protective cover to the device. Removing the protective cover 1. Unscrew and remove the fixing screws on the protective cover. Figure 5: Unscrewing the protective cover fixing screws 1 4 x M6 fixing screws 2. - Page 24 5. Tighten the nuts crosswise with 60% of the max. tightening torque. NOTICE! Damage to the holes due to a tightening torque that is too high. Tighten the nuts crosswise with 100% of the tightening torque and con- tinue to retighten the nuts with 100% of the tightening torque until the screws can no longer be turned further.

4. Then tighten the fixing screws crosswise up to the maximum tightening torque. Figure 7: Mounting the protective cover 1 4 x M6 fixing screws Mounting the oil drainage unit 1. Remove the plastic cap from the oil escape opening. 2. Insert the o-ring gasket included in the delivery into the 4-hole connection. 3. -
Page 26: Cable Recommendation
WARNING Danger of death or severe injury! Danger of death or severe injury due to improper electrical con- nection of the pressure relief device. When the pressure relief device trips, the transformer must be immedi- ately de-energized by the circuit breaker. Ensure that the pressure relief device's signaling contact is correctly looped into the tripping circuit of the transformer circuit breaker. - Page 27 4. Unscrew the screws on the terminal strip (3, 6, 9 or 12 x M3, bladed screw- driver). 5. Remove an amount of sheathing from the double-insulated cable appropri- ate for the wiring, strip off 7 mm of insulation from the individual wires and cap off with ferrules.

Page 28: Commissioning
6 Commissioning Prior to commissioning the transformer, perform the following checks. If any- thing is unclear regarding the checks or troubleshooting, please contact CEDASPE S.r.l [►Section 1.1, Page 5]. 6.1 Filling with oil and performing the venting test WARNING Danger of explosion and danger of poisoning! Explosive gases in the device can deflagrate or explode and re- sult in severe injury or death. -
Page 29: Leak Test
6.2 Leak test The device is filled with insulating fluid. 1. Check the tightness of the flange connection. 2. If the connection is not tight, check the gasket and replace it if necessary.
