Installation Of Optional Cp Interface System - Gentherm 5220 Operating Manual

28142 Rev 15
Clean Fuel: The fuel used to operate the 5220 TEG must be clean and dry. See Technical
Specifications section for the full gas specification for fuel supplied to GPT's TEGs. If dirty fuel
is anticipated, then a customer-supplied in-line fuel filter is recommended. For further
information regarding the condition of fuel supplied to the TEG, please contact GPT.
Low Temperature: Regulator freeze-off can be minimized by regulating the incoming supply
pressure to 25 PSI (172 kPa). When using propane at temperatures below -30ºC (-22ºF),
special consideration must be given to the vaporization of the fuel.
Connect the customer load directly to the TEG using the following procedure. If the TEG is
equipped with the optional CP interface system, then see the Installation of Optional CP
Interface System topic below. Follow these steps to connect the customer load:
1. Bring the customer load wires through the strain relief bushing (located on the L/C or
Limiter enclosure). Allow enough wire to connect to the terminal block TB-1.
Use only copper wire, properly sized for the load current. Electrical
NOTE:
connections must be made in accordance with local electrical codes.
2. Tighten the screws on the strain relief bushing.
3. Connect the customer load wires to TB-1:
12 V: Connect the load at terminals 5(+) and 4 (-) (Figure 13).
24 V: Connect the load at terminals 7 (+) and 6(-) (Figure 14).

Fuel supplied to the 5220 must not exceed 50 PSI
(345 kPa) under any circumstances. If fuel pressure

exceeds this limit, damage to the fuel system may
occur.
The customer output from the 5220 must be wired
through a suitably sized circuit-breaker or fuse that

the station battery, load, and other voltage sources in
the system. Failure to do so may result in damage to
customer equipment or to the TEG's own electronics.
