INSTALLATION
BEFORE INSTALLING THE PPC5000 CONTROL
Wiring Base
Install the PPC5000 where the relative humidity never reaches the saturation point. The PPC5000
system is designed to operate in a maximum 80% relative humidity continuous, non-condensing
environment. Do not install the PPC5000 system where it can be subjected to vibration in excess of
0.5G continuous maximum vibration. The PPC5000 system is not a weather tight enclosure.
Wiring must comply with all applicable codes, ordinances and regulations.
1.
Wiring must comply with NEC Class 1 (Line Voltage) wiring.
2.
Limits and interlocks must be rated to simultaneously carry and break current to the ignition
transformer, pilot valve and main fuel valve(s).
3.
Recommended wire routing of lead wires:
a. Do not run high voltage ignition transformer wires in the same conduit with any other
wires.
b. Do not route flame detector lead wires in conduit with line voltage circuits. Use separate
conduit where necessary.
4.
Maximum wire lengths:
a. The maximum lead wire length is 200 ft. (61 meters) to terminal inputs (Operating limits,
interlocks, valves, etc.).
b. Modbus communications: The maximum cable length of wire is 3200 feet (1000 meters)
for RS-485.

Mounting the Control Unit
This section contains basic installation
information concerning the PPC5000 sys-
tem (controller and panel-mounted dis-
play), the servo-motors and the wiring.
The control unit is designed to be fitted
inside the burner control cabinet. The cabi-
net should have a minimum protection
level of NEMA 12 (IP40) for indoor use,
or NEMA 4 (IP54) for outdoor use.
The control unit should be mounted so that
the circuit boards within it are vertical, to
maximize cooling efficiency.
A clearance is required of a least 80mm
above and 20mm below and at the sides of
the controller enclosure.
The operating temperature range of the
equipment is 0 to 60°C.
CAUTION: Ensure that electric power is turned off. Refer to SN-100 for recommended
grounding techniques.
Be aware that power to some interlocks (operating controls, air flow switches, modulating
circuits, etc.) may be derived from sources other than what is controlling the PPC5000.
