Disconnect heater and lock out
from electrical supply before
installing or servicing.
•
Always

WIRING OF THE FSA SERIES HEATERS:
1. The FSA-14 and FSA-31 models are available in
single phase only. All FSA-43, FSA-65 and FSA-95
models (except the FSA-4327-1, FSA-6527-1 and
FSA-9527-1) can be wired for single phase or three
phase applications. See wiring diagrams on page
14.
2. Remove the cover from the terminal box.
3. Connect the lead wires to the 90°C rated supply
wiring routed into the splice box with wire nuts or
other safe mechanical means. Black and white
supply leads can be connected to either element
lead wire. Be sure green lead from supply and
green (bonding) lead from the terminal box are
connected.
4. Reinstall splice box cover.
5. Apply power to circuit.

FOR ALL HEATERS
Wiring procedures and connections shall be in
accordance with the national and local authority
having jurisdiction. The FSA series heaters do not
have any on board controls and therefore must
be used in conjunction with an applicable control
center or be wired to a listed, properly rated safety
switch for on/off control.
Always disconnect the power at the circuit breaker or
disconnect switch before installing electric power to the
heater. If the breaker or disconnect switch cannot be
seen from where you will be working, lock it in the open
position and tag it to prevent unexpected application
of power. Failure to do so could result in fatal electric
shock. Do not depend on a thermostat or other switch
as the sole means of turning off power to the heater.
When bringing supply wiring to the heater always route
it away from the area directly above the heater and
away from the sides of the heater where temperatures
may be dangerously high.
"Bonding is the intentional electrical connection
of all non-current carrying metal parts to the
equipment grounding (green) conductor of the
heater and then terminating this green conductor
to the green conductor of the power supply to form
a low-impedance path back to the power supply
so that safety devices (circuit breakers, fuses)
can quickly remove dangerous touch voltage from
these parts when a fault occurs.
Always securely connect the green conductor
from the power supply to the green conductor
of the heater.
