Protective Earthing; Electrical Noise - ProFire PF2200-SB Product Manual

V 4.0

3.3.3 PROTECTIVE EARTHING

For the PF2200-SB-A, the metal enclosure must be properly bonded to earth ground by the installer.
Bonding must be carried out in accordance with the local electrical code (e.g. NEC in the United States
and CEC in Canada).
To ensure proper functionality of the flame detection circuit, Profire recommends the DC power supply
reference be tied to Earth Ground.

3.3.4 ELECTRICAL NOISE

Due to the variability of installation (e.g. load configuration, wiring, etc.), a ferrite bead may be required
to suppress power supply related noise on the input power to the PF2200-SB-B. Typically this is only
needed for long power line / load line run lengths and at higher load currents (e.g. >2A).
