Installation
JC-10D2 Indicator Mounting:
The JC-10D2 Indicator is designed for flush mounting in an
enclosure located in an indoor NEMA 12 environment.
The JC-10D2 should not be subjected to excessive vibration.
Continuous operation is guaranteed over the 32-131 F
(0-55C) ambient operating range.

Wiring:
Warning
Disconnect all sources of power before installing or servicing this equipment. Multiple Disconnects may be required.
Burner interface wiring must be performed by an experienced burner service technician.
All wiring must comply with all local and national electrical codes. Tighten all terminals to 4.4 in-lb. Wire must be stranded copper,
12-24 ga., 150V / 75 C insulation minimum. AC and DC wiring must be separated to prevent electrical noise coupling. Do not run
AC and DC wires in the same conduits. Use shielded cables where shown, connect shields only where shown, insulate all other
shields to prevent accidental grounding. Ignition transformer and motor VFD wiring are particularly electrically noisy and should be
kept away from the thermocouple extension wire, and also all other AC and DC wiring.
If the 4-20 mA output will not be used, jumper terminal 40 to 41 to prevent the OUTPUT FAILURE error message.
Relay contacts are shown with power removed from the JC-10D2.
All DC wiring is isolated from Ground. All DC wiring '-' terminals are connected together internally.
RS485 is electrically Isolated from all other DC and AC wiring.
Terminals 1-9 are Line Voltage AC. Terminals 31-50 are low voltage DC.
An external Line Voltage supply switch or circuit breaker, marked as the disconnect for this instrument, suitably located
and easily reached, and complying with IEC 60947-1 and -3 must be provided.
Fuse:
3.15 amp Slo-Blo, 250 V, 5x20mm (Littlefuse 02153.15HXP, Belfuse 5ST 3.15-R, Preferred Utilities 16740-3.15S)
Caution
: To reduce the risk of fire, only replace fuse with the same type.
