When delivering to the final site installation the transformer(s) should be fixedsecurely within the vehicle for transportation. It is advised that the transformer(s) andGLS-100 R coating be inspected before installation.

During on loading and offloading it is advised that two or more competent personmanually lift the transformer in place. Note the Health and Safety Executive ManualHandling Charts (MAC) assessment is attached in Appendix B for reference and can beused to aid any manual handling risk assessment. However, this does not invalidatecompetent person(s) from their responsibilities. The Manual Handling OperationsRegulations 1992 (as amended) shall be adhered to in this regard. FT transformersadvise the use of a mechanical lifting aid such as a stacker for weights 40kg and belowas shown in figure 5

3.1.2 Installation

Before installation commences the installer must carry out a risk assessment. Themounting rails, brackets or other such arrangement must be assessed for its capabilityof bearing the transformer weight.

It is advised that the transformer be mounted at the lower portion of any cubicle orrack to reduce the risk of stress on any such cubicle or rack.

Although the FT-100 R coating is extremely durable, care must be taken not to scratchit. If damage does arise, please see Section 7 Repair Procedure for FT-100 R

The transformer must be mounted in the orientation shown in figure 3 below with thefixing holes to the bottom. The transformer must be securely fixed to the mountingrails, brackets or other such arrangement capable of bearing the transformer load. ThePlastic nuts and bolts supplied must be used ONLY. If these are lost, please contact FTTransformers and arrangements will be made to supply replacements. Otherwise,plastic nuts and bolts can be readily obtained from the standard electrical wholesalers.
