Electrical Connections
The DIG-220 uses both high and low voltage connections. High voltage connections will be made for providing the direct inpu
t
power. Additional high vol
tag
e connections
may be
made to the filter pump from the DIG-220. Low voltage connections will be made to the Tri-
s
ensor and
Pool Pilot Cel
l. Additional low voltage connections are provided for
optional equipmen
t
such as a pH/ORP or electronic controller.
Grounding and Bonding
Connect a ground wire from the primary electrical input to the grounding lug located inside the box. Also ground any piece
o
f high voltage equipment that is connected to the
DIG
-
220 relay. The DIG-220 must also be connected to the pool bonding system with an
8 AWG (6 AWG for Canada)
wire.
A lug
is provided on the bottom exterior of the
unit.
AC LINE IN
The DIG-220 is pre-wired from the factory for 230
Vac
using a 3-ampere fuse on th
e AC
input. Short test leads are attached to the AC terminal strip
and must be removed
prior
to installation.
Determine Incoming Voltage Requirements
I
f 115 Vac input power is required
,
please follow steps in section entitled ”For incoming voltage of 115 Vac” on pages-15.
For incoming voltage of 230 Vac:
For incoming voltage of 230 Vac, confirm the “TRANSFORMER PRIMARY” is wired as indicated in FIG-11G.

WARNING
Mounting the Control Unit Continued:
Read the following section complety before proceeding (damage to wires and connectors may occur):
1.
Level and tape the mounting template to the selected
mounting location. Mark the wall for the four (4)
mounting holes.
2.
Plastic anchors and screws have been provided
for concrete or stucco walls. Drill and install
anchors and screws. Leave a 1/4” gap from the
wall when tightening the screws.
3.
Loosen, but do not remove the four (4) thumbscrews
on the sides of the unit cover. Carefully slide off the
outer housing cover. Disconnnect the 3 plugs that
connect to the display (mounted inside the cover).
The display circuit board does not need to be removed
from the cover.
4.
Safely set the cover aside.
8.
See
Electrical Connections
on page-14, 15,
& 16 for terminal connections.
9.
After terminal connections have been made
,
reverse steps 3-8 to re-install the metal and external
covers.
Make sure to route and connect the 3 cables
through the side slot in the protective cover properly,
then replace the outer housing cover after first
connecting the 3 plugs (that were disconnected
in step 3).
5.
Hang the DIG-220 on the four mounting screws.
Using a long shaft slotted screwdriver, tighten the
screws through the black plastic access holes.
6.
For access to the electrical terminal strip, remove
the four screws and lift off the inner metal protective
cover.
7.
Safely set the metal protective cover aside.
