INSTALLATION
MOUNTING AND WIRING
Refer to Typical System Wiring Diagram on page 4 and
Typical System Wiring Table on page 5
All wiring should be installed according to local and national
electrical codes and ordinances.
The control must be secured to an area that will experience a
minimum of vibration and remain below the maximum ambient
temperature rating of 175
o
F. The control is approved for minimum
ambient temperatures of -40
o
F.
When mounting the control, any orientation is acceptable.
Choose a location that will not damage, obstruct or place stress
on the control terminations, system wiring harness or system
components.
Refer to the wiring diagram and wiring table when connecting
the 50M58 control to other components of the system.
UL approved, 105
o
C rated 18 gauge min., stranded, 1/32" thick
insulation wire is recommended for all low voltage safety circuit
connections.
UL approved, 105
o
C rated 16 gauge min., stranded, 1/16"
thick insulation wire is recommended for all line voltage
connections.
After installation or replacement, follow appliance manufacturer's
recommended installation or service instructions to insure
proper operation.
The 50M58 has only one serviceable part – an automotive type
fuse, which protects the low voltage transformer from damage
if its output is short-circuited. If the fuse has opened up, correct
whatever caused the short circuit and replace the fuse with only
a 3 amp automotive type fuse. If the fuse is not the cause of
the control's problem, replace the entire 50M58 control. There
are no other user serviceable parts.
Additional jumper wires are included to be used if the original
wiring does not reach the control after mounting. Refer to the
furnace wiring diagram for proper connection of wires.
Some applications will require connection to terminal FP2. If
the control being replaced does not have this connections, it is
not needed in the application and connection to terminal FP2
is not required.
