Installation
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.
