Before you start
- Foreign material contamination: cover the transfer switch and solenoid mechanism during installation
- Hardware damage: use correct size tools to prevent rounding bolt heads/nuts
Procedure
- Check the system voltage and frequency against the transfer switch nameplate and the source/generator set nameplate; do not install if different
- Plan the installation using the enclosure dimension (ADV) drawings in Section 6
- Select a mounting site complying with local electrical code restrictions for the enclosure type; mount as close to load and power sources as possible
- NEMA 3R enclosures: support the front panel while removing screws, pull the bottom of the panel out and down until the top clears the enclosure, remove the inner panel
- NEMA 3R enclosures: turn the locking tab out while open so the door can be locked with a padlock after installation
- Wall mounting: mount to a wall or other rigid vertical supporting structure using the dimension drawings for hole locations; use shims to plumb the enclosure
- Cover or remove internal components to protect from drill chips or debris during installation; vacuum out debris (do not use compressed air)
- Tighten mounting screws to 2.9 Nm (26 in. lb.) when reinstalling components
- Use washers with mounting screws on NEMA 3R enclosures to protect the gaskets sealing the mounting holes
