Backplate Drilling Procedure
Cover any units already mounted to the backplate to protect them from stray metal filings before drilling the mounting holes.
Refer to the diagram on the previous page and drill the mounting holes into the backplate. The holes must be positioned accurately.
For each phase assembly:
• Drill 5 holes to suit M10 flush-fitting inserts. Fit the nut inserts.
IMPORTANT
The nut inserts MUST be flush-fitting so that the phase assembly foot rests on the backpanel. If the phase assembly is
mounted incorrectly it will damage the moulding.
Connecting the Fishplates
Before fitting the Phase Assemblies to the back panel,
loosely fit the fishplates to the right hand side terminals
(A+, A-) of each Phase Assembly.
The fishplates are fitted with M10 nut inserts. Secure the
fishplates behind the terminals using M10 bolts (8:8 steel
grade) and spring disc washers (preferred, or single coil
spring washer). Hand tighten only.
Fitting the fishplate behind the terminal allows the phase
assembly to easily be lifted away from adjacent phase
assemblies and any associated busbar connections.
NOTE 8:8 minimum steel grade bolts are
recommended for all busbar connections and
mounting duties.
