JH-DC OPERATOR INSTALLATION GUIDE

General Specifications

1.

All wiring must conform with all local codes and ordinances.

2.

All wire connections must be made with MTW or THHN
type wire, with insulation thickness of at least 1/32”.

Power Connection Specifications

1.

Select the appropriate wire gauge from the chart at the
bottom of the page based on length of run. The distance
shown on the chart is measured in feet from the operator
to the power source. DO NOT EXCEED THE MAXIMUM
DISTANCE! These calculations have been based no stan-
dard 115 Volt supplies with a ten percent (10%) drop
allowance, taking into account motor inrush and other
operator requirements. Calculations are based on the
National Electrical Code, Article 430.

2.

When large gauge wire is used, a separate junction box
(not supplied) may be needed for the operator power
connection.

Control and Accessory Specifications

1.

Control wiring must be run in a separate conduit from power
wiring. Running them together may cause interference and
faulty signals in some accessories.

2.

All control devices are now 24 Volt DC, which can be run
considerable distances.

3.

A three wire shielded, conductor cable is required to
connect master and slave operators. You must use Belden
8760 twisted pair shielded cable (or equivalent) only, OSCO
part number 2500-1982, per foot. See page 

13

 for details

of this connection, as well as dip switch selection. Note:
The SHIELD wire must be connected in both master and
slave operators.

Power Unit to Control Box Specifications

1.

All wires running from the power unit to the control box
must be enclosed in rigid or flexible metal conduit. Wire
connections must be mechanically and electrically sound,
with accepted crimp type or wire nuts at the power unit
and spade terminals or stranded conductors with all
strands soldered together at the control box terminal strip.

2.

Wires from the control box to the power unit for motor
power (M1 and M2) must be minimum 12 gauge wire.

3.

Wires from the control box to the power unit for limit
switches must be minimum 18 gauge wire.
