2.1INTRODUCTION TO INSTALLATION
This equipment has been wired and tested at the facto- ry. Installing the switch includes the following proce- dures:
•Mounting the enclosure.
•Connecting power source and load leads.
•Connecting control wiring.
•Connecting any auxiliary contact (if needed)
•Installing/connecting any options and accessories.
•Testing functions.
2.2UNPACKING
Carefully unpack the transfer switch. Inspect closely for any damage that might have occurred during ship- ment. The purchaser must file with the carrier any claims for loss or damage incurred while in transit.
Check that all packing material is completely removed from the switch prior to installation.
Attach any lifting device to the transfer switch mounting holes or brackets only. DO NOT LIFT THE SWITCH AT ANY OTHER POINT.
2.3MOUNTING
Transfer switch components are generally mounted in a standard NEMA 1 type enclosure (Figure 2.1).
Section 2 — Installation
Generac 100 Amp Transfer Switch
Install the transfer switch as close as possible to the electrical loads that are to be connected to it. Mount the switch vertically to a rigid supporting structure. To pre- vent switch distortion, level all mounting points. If nec- essary, use washers behind mounting holes to level the unit.
2.4CONNECTING POWER SOURCE AND LOAD LINES
DANGER
Make sure to turn OFF both the normal (Utility) and standby (generator) power supplies before trying to connect power source and load lines to the transfer switch. Supply voltages are extreme- ly high and dangerous. Contact with such high voltage power supply lines causes extremely haz- ardous, possibly lethal, electrical shock.
Wiring diagrams and electrical schematics are provided in this manual. Power source and load connections are made at a transfer mechanism, inside the switch enclo- sure.
Handle transfer switches carefully when
!installing. Do not drop the switch. Protect the switch against impact at all times, and against construction grit and metal chips. Never install a transfer switch that has been damaged.
