Use the electrical knockouts provided at the bottom of the
enclosure. Do not make additional holes in the enclosure.
Set the voltage switch to the appropriate line voltage.
CONCERNING THE ALARM CONNECTION: There are two types of
alarms in the industry. One type activates when current is cut off at its
input, whereas the other activates when current is supplied at its input.
For an alarm of the first type, use the NC terminal as shown on the
wiring diagram. For an alarm of the second type, use the NO terminal.
ALL WIRING MUST BE DONE BY AN AUTHORIZED ELEC-
TRICIAN AND MUST COMPLY WITH APPLICABLE CODES,
!
LAWS AND REGULATIONS. BE SURE POWER IS OFF
BEFORE DOING ANY WIRING TO AVOID ELECTRICAL
CAUTION
SHOCK AND EQUIPMENT DAMAGE.
TEMPERATURE PROBES: If your PF-6 unit is supplied with a tempera-
ture probe, connect it to terminal PROBE #1 and set internal switch #5
to ON. Note that the PF-6 will operate with no temperature probes
connected to it. However, the room temperature position on the func-
tion selector will not function in this case.
This probe can be extended up to 500ft (150m).
To extend the probe:
Use a shielded cable of outside diameter between 0.245 and
0.260 in (6.22 and 6.60 mm) to ensure the cable entry is liquid-
tight (the cable dimension must not be under 18 AWG).
It is preferable to solder the cable joint to ensure a proper
contact between the two cables.
Do not ground the shielding.
