Installation
This section describes how to install and wire the Model 915 power control system. The
features and options mentioned here are identified in the model number found inside the
enclosure.
!WARNING!
Hazardous voltages are present at the main disconnect switch and load terminals. Setting the
setpoint potentiometer or control signal to minimum does NOT eliminate these hazardous
voltages.
Always remove AC lien voltage from the system before making contact with the internal
assemblies, line or load wiring, or fuses. Also remove AC line voltage from the system before
making connections, equipment changes, or resistance measurements.
Mounting the System
The Model 915 Power Control System may be mounted to a wall with the supplied brackets,
on a stand, or bench. The Model 915 must be mounted in a vertical position. When mounting
to a wall, the top of the enclosure should not be over 74 inches (1880 mm) above the floor.
Figure 3-1 shows the mounting dimensions using the supplied brackets. Attach the brackets to
the enclosure with the hardware provided. Allow a minimum of 4 inches (100mm) clearance
on the right and left sides of the system. Allow a minimum of 30 inches (762 mm) in front of
the system.
