electrical service depends on the distance of the operator from the breaker panel. Refer to Table 1 to determine the correct wire size. The NOMINAL column is the ideal distance from the breaker panel to the operator for a given wire size and voltage. The distances shown in the MAXIMUM column should never be exceeded and should only be used where it is known that the voltage at the power panel will never be less than 105 VAC. (The HDSWG 1000 will operate at a voltage as low as 95 VAC measured at the input

terminals to the operator. The "maximum distance" of Table 1 is calculated to supply 95 VOLTS to the HDSWG 1000 during the "stop cycle" when the line voltage is at 105 VOLTS.) NOTE! FOR
A
Class 2 low voltage wiring from external controls such as a key pad, card reader, telephone entry device, etc. must be brought to the HDSWG 1000 CONTROL BOX by a separate conduit from the 115 VAC electrical hook up conduit. Low voltage control wires MUST NEVER be routed in the same conduit as the HIGH VOLTAGE power wires.
Note! The limit switch wires from the HDSWG 1000 CONTROL BOX to the HDSWG 1000 MECHANICAL UNIT ARE LOW VOLTAGE WIRES AND MUST BE ROUTED IN A LOW VOLTAGE CONDUIT TO THE CONTROL BOX.
WARNING!
AVOID ELECTROCUTION:
DO NOT ROUTE LOW VOLTAGE WIRES IN SAME CONDUIT AS HIGH VOLTAGE WIRES. FOLLOW ALL LOCAL ELECTRICAL CODES OR THE NATIONAL ELECTRICAL CODE.
OTHER VOLTAGES AND THREE PHASE SYSTEMS.
The HDSWG 1000 can operate at other voltages or on three (3) phase systems. To operate at 440 VAC it will be necessary to install an external step down transformer. The transformer should be located in a separate electrical box and protected by suitable circuit breaker and/or fusing. A 440 Volt rated switch should also be installed. Follow local electrical codes or the National Electrical Code. The transformer selected should be UL LISTED and be rated for 500
IF TWO MECHANICAL UNITS ARE TO BE USED FOR A BI- PARTING GATE SYSTEM, THEN A 1000
Operating from a three (3) phase line will require the use of a 230 VAC rated HDSWG 1000. The HDSWG 1000 may be operated from a 230 Volt "Delta" line or a 120/208 "Y" line. In either case, ONLY one "leg" of the three phase line will be used. The unbalance of the line will be minimal since the full rate current of the HDSWG 1000 at 220 VAC is only 2.2 amperes. (4.4 Amperes for a
GROUND.
SERVICE CONDUIT
For new installations the conduit for the High Voltage may be brought to a junction box near where the HDSWG 1000 CONTROL BOX will be located or it may be brought directly to the Control Box.
