Automatic Transfer Switch Owner’s Manual 9
Section 3: Installation
Introduction to Installation
This equipment has been wired and tested at the factory.
Installing the switch includes the following procedures:
• Mounting the enclosure.
• Connecting power source and load leads.
• Connecting the PWRcell inverter control conductors.
• Installing the current transformers.
• Connecting the PWRcell ATS Controller.
• Configuring the inverter.
Inverter Versions Compatibility
The PWRCell ATS is compatible with all versions of the
PWRCell inverter, however some additional connections
are necessary on the X7602 model compared to the
XVT076A03.To determine the version of your inverter,
refer to the product label on the bottom right hand side of
the enclosure. You will see the model number “X7602” or
“XVT076A03”. Note that some steps are marked “X7602
Only” - these are not required if you have the
XVT076A03.
Mounting
Mounting dimensions for the transfer switch enclosure
are in this manual. Enclosures are typically wall-
mounted. See Drawings and Diagrams.
This transfer switch is mounted in a UL type 3R
enclosure. It can be mounted outside or inside and should
be based on the layout of installation, convenience and
proximity to the utility supply and load center. 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 prevent switch
distortion, level all mounting points. If necessary, use
washers behind mounting holes to level the unit.
Open Enclosure
See Figure 3-1. First, remove outer cover (A):
1. Remove thumb screw (B).
2. Slide slot (C) over retention tab.
3. Lower cover until clear of top flange (D), and pull
away from enclosure.
4. Remove inner panel (E).
NOTE: Inner panel (E) is ONLY on Service Entrance
Rated Models.
5. Loosen nut (F) until it clears t-slot (H) in inner
panel.
6. Grasp inner panel at two cutouts (G—left and
right). Tilt inner panel as shown, passing nut
through t-slot.
7. Lower inner panel until clear of two retention slots
(J—left and right sides), and pull away from
enclosure.
