1. Important Information
This manual contains important safety and operating instructions and specifications for DKS Model
1000 Inverter / Backup Power System. This manual is the property of the owner of the equipment and
must be left in their possession after the installation of the product is complete. SAVE THESE
INSTRUCTIONS!
The 1000 Watt Inverter (1000-080) can be used to power a single, 1/2 HP gate operator system
when in continuous duty mode, or can be used with two (2) 1/2 HP gate operators when open
upon power failure mode is used.
The 1500 Watt Inverter (1000-081) can be used to power a bi-parting, 1/2 HP gate operator
system; or it can be used to power a single, 1 HP gate operator system.
The DKS Model 1000 Power Inverter uses a modified sine wave as the AC output. Because of
this, vehicular gate operators that use a current sensor device (ERD) as an inherent
entrapment protection system may experience false entrapment inputs when the inverter
powers the gate operator. DKS gate operators that use an ERD have been specifically
designed to work within the limits of the modified sine wave.
2. Important Precautions
•CAUTION – The Model 1000 produces lethal voltages. It should be installed by a qualified
electrician and operated with care and attention. The batteries are capable of supplying
hazardous current. Follow the instructions carefully.
•CAUTION – Risk of Energy Hazard, 12 V, 35 Ampere-hour battery. Dangerous voltages
are present even when the AC is off. Remove personal metal items such as rings, bracelets,
necklaces, and watches when working with electrical circuits. These items can cause a short-
circuit current high enough to weld a ring, or the like, to metal causing severe burns.
•CAUTION – Disconnect the charging source prior to connecting or disconnecting the
batteries. Do not install or connect batteries to this unit until instructed to do so. Failure to
comply with this instruction can cause damage or complete failure of the inverter unit.
•CAUTION - To reduce risk of injury, use only the type of batteries specified. Maintenance-
Free, Rechargeable, Nonspillable, Sealed Lead-Acid (SLA), 12-Volt, 35.0 AH.
•BATTERIES MUST HAVE SCREW TYPE TERMINALS. DO NOT USE BATTERIES WITH
CLAMP TYPE TERMIANLS.
•CAUTION – Do not dispose of batteries in a fire. The battery may explode. Batteries should
be taken to a recycling center.
•CAUTION – Do not open or mutilate the batteries. Released electrolyte is harmful to skin
and eyes. It is toxic.
•Never charge a frozen battery.
•Someone should be within range of your voice to come to your aid when you work near
batteries.
•NEVER smoke or allow a spark or flame in vicinity of the batteries.
•Be extra cautious when working with metal tools on and around batteries. Use tools with
insulated handles. Do not lay tools or metal parts on top of the batteries. The potential exists
to short-circuit the batteries or other electrical parts that may result in a spark that could
cause an explosion.

CAUTION – RISK OF ELECTRICAL SHOCK PRESENT!
CAUTION – Risk of electrical shock – hazardous live parts inside this unit are
energized from the battery supply even when AC power is disconnected.
CAUTION – Risk of electrical shock. AC Input and AC Output terminals can be
energized even with AC INPUT and AC OUTPUT switches turned off.

4. Mounting
The Model 1000 inverter has three (3) mounting holes provided on the back of the cabinet. The
mounting holes should be used to mount the model 1000 to a vertical surface. In addition, there are
five (5) 3/4” conduit knockouts; three (3) on the bottom and two (2) on the back. These should be
used for wiring.
IMPORTANT: Do not drill any additional holes into the Model 1000 housing. Drilling produces metal
filings, which can cause shorts on the circuit board and will void the warranty.

Location
Prior to installing the Model 1000, careful thought must be given as to where the unit will be installed.
The system operates best when it can be installed as physically close as possible to the equipment
that it is intended to operate during power outages. This reduces line loss.
The effective capacity of a battery is reduced when cold. This phenomenon is more significant with
lead-acid type batteries than with other batteries. When the internal temperature of a lead-acid
battery is 32°F (0°C), the capacity can be reduced by as much as 50%. If extremely cold
temperatures are expected, you should consider installing the Model 1000 in a heated equipment
room.
The Model 1000 should be protected from high temperatures as well. High battery temperatures will
result in short battery life. Install the backup system in a shaded area or inside an air-conditioned
equipment room if extremely high temperatures are the norm.

5. Read Before Wiring
WARNING! Do not connect batteries until installation and wiring is complete. The batteries
will be the last component to be connected.
Wiring of the Model 1000 should be performed by a qualified licensed electrical contractor to
insure that the installation complies with local codes and ordinances.
The output of the Model 1000 should at no time be connected to public power or a generator.
Use No. 12 AWG copper wire for AC input and AC output connections.
GROUNDING INSTRUCTIONS - This backup power supply must be connected to a grounded,
permanent wiring system.
WARNING!! THE INVERTER IN THIS BACKUP POWER SYSTEM IS NOT REVERSE-POLARITY
PROTECTED!! If the positive terminal of the battery is connected to the negative terminal of
the inverter and vice versa, the probable result is failure of every power FET in the inverter. To
compound your misfortune, this type of failure is very obvious AND IS NOT COVERED UNDER
THE WARRANTY. Pay close attention and double check when making the battery connections.
CONNECTING THE BATTERY CABLES WILL CAUSE AN ARC USUALLY ACCOMPANIED BY A
"SNAP". THIS IS NORMAL - DON'T LET IT SCARE YOU.
WARNING!! Never disconnect the batteries while the system is delivering power or the battery
charger is operating. Always turn the system OFF first.
6. Wiring Instructions

7. LED Status Indicators
The Model 1000 has 12 LED indicators to show the status of the inverter, batteries and to assist in
troubleshooting.
LED Description
UTIL OPER GREEN LED indicating that the 115 VAC power output at J2 is sourced from the utility
company and the inverter is in stand-by mode.
INV ON YELLOW LED indicating that primary (utility company) power is unavailable and the 115
VAC power at J2 is being sourced from the inverter.
B BAD RED LED blinks when the battery has been tested to be low, comes on steady when battery
is bad.
B OK GREEN LED indicates that the battery has been tested and is good.
BULK YELLOW LED indicates that the battery is being bulk charged; blinking indicates that the
battery is at 90% of full charge.
TRICK GREEN LED indicates that the battery is fully charged and the system is applying a trickle
charge to it to maintain the full charge.
TEMP RED LED indicates that the battery is not being charged because the temperature is outside
the battery safe operating range: 23°F (-4°C) to 126°F (52°C).
SHDN RED LED located in the upper left of the circuit board. This LED is ON when the system has
shut down the inverter because of low battery voltage.
110V ON RED LED (2) indicates that 115 VAC is present at the power output terminal (J2).

AC Power
Loss
When primary AC (Utility power) is
lost – relays will activate immediately
to open gate, then the system will
enter a shut down condition.
When primary AC (Utility power) is lost –
the system will provide AC power to the
gate operator(s) until the battery is too
weak to continue operation. At this time,
the system will activate each relay
individually 55 seconds apart, and then
shut down.
6 Low Battery When battery is too weak to sustain
operation – system shuts down. When battery is too weak to sustain operation – activate relay to open gate then
shut down.
