Instruction Manual
HPH-4
High Power HID controller

When trying to control more than one HID (High Intensity
Discharge) lighting system, you can either use a bunch of timers
OR… a device like the HPH-4. The HPH-4 makes it simple to
control up to 4000 watts of lighting from a single timer or controller.
The HPH-4 has four UNIVERSAL receptacles that accept either
a 120 volt (Nema 5-15P) or 240 volt (Nema 6-15P) male plug from
your HID ballasts.
The user provides a single 240 volt, 30-amp circuit to the HPH-4.
An internal heavy-duty relay switches the lights On and Off. The
relay is turned On and Off by connecting the 15 ft “trigger cable”
(a 120 volt power cable) to a timeclock or controller like the
MDT-1. When the timeclock or controller turns ON, the trigger
cable caries the voltage to the relay inside the HPH-4, the relay
activates, and the (4) receptacles are energized turning the lights
connected to the unit ON.
The HPH–4 is housed in a
sealed, aluminum heat sink
enclosure and can be mounted
using the wall mount bracket
included.
Heat from the relay and inter-
nal components is radiated
outside the enclosure to ensure
long life and cool operation.
The user must provide and
connect a 240 volt, 30-amp circuit to the HPH-4. (see below)

Troubleshooting & Specs
Introduction
WARNING: Installation must be completed by qualified person(s).
Installation must be done in accordance with state and local electrical
codes.
Troubleshooting
Problem: The timeclock or controller is turning On the relay and
red indicator light but the lights are not turning ON.
Check the main power. If the relay is turned ON, and the ballasts are
connected, the main power may not be turned ON.
Problem: The red indicator and relay do not turn ON.
Check the timeclock or controller that the trigger cable is connected to.
The trigger cable provides a 120-volt “signal” to the HPH-4 that turns
ON the relay and red indicator. Try plugging the trigger cable into a
known 120-volt power source. If it works, then the problem is with the
timeclock or controller you are using to turn the HPH-4 ON.
Problem: The circuit breaker for the main power keeps shutting
OFF.
The circuit breaker is protecting the circuit from overloading. It is pos-
sible that one or more of the ballasts have failed (shorted out). Try un-
plugging each ballast one at a time to determine which ballast has a
problem.
It is also possible that the amperage is too much for the circuit breaker.
Verify the circuit breaker is a 30-amp, 2-pole breaker.
Problem: The red light and relay are OFF but the lights remain
ON.
It is possible that something is wrong with the heavy-duty relay. If the
trigger cable is unplugged and the lights remain ON, contact the
factory.
Problem: The red light is ON but I do not hear the relay turning
ON and the lights do not turn ON.
It is possible that something is wrong with the heavy-duty relay. If the
red light is ON, and the lights do not turn ON, contact the factory.
Some of the more common questions and problems are listed here.

The HPH-4 CAN be used to control ballast that are not capable of being
operated on 240-volt power however, the number of ballast that can be
operated is greatly reduced if they are operated on 120-volt. Here is a list of the
number and wattages that can be used on 120-volt power.
250 to 400 watt = (4) ballasts
600 watt = (4) ballasts
1000 watt = (2) ballasts
Notice that only (2) 1000 watt ballast can safely be operated at 120-volt. Each
1000 watt ballast consumes 9+ amps each. The user must provide a single-
pole, 30-amp circuit breaker and #10 AWG wire when used with 120-volt.

A quick look at the HPH-4…
NOTE: The HPH-4 is a high-power device. Locate the HPH-4 away
from other sensitive electronics. Even though the enclosure is sealed, DO
NOT spray the unit with water... especially the receptacles.
Provide a dedicated circuit to the HPH with overload protection.

Installing the HPH-4
In order to ensure a safe and proper installation of the HPH-4,
follow the steps below.
1) Select the location for the device to be used. Keep the unit away
from water. Determine where the trigger cable will be connected to
the timeclock or controller. (Extension cords can be used to connect
the trigger cable to the timeclock if necessary.)
2) Ssecure the HPH-4 to the bracket using the three screws included
with the unit.
3) The wall mount bracket can then be mounted to the wall using
appropriate screws.
4) Remove the enclosure cover to expose the relay and terminals.
5) With the main power turned OFF, connect the main 240 volt /
30-amp power to the terminals provided inside the enclosure.
(See diagram / photo on the next pages.)
6) DO NOT turn ON the main power yet. Connect the 120 volt
trigger cable to the timeclock or controller that will be turning the
HPH-4 ON & OFF.
7) Energize (over-ride) the timeclock or controller and verify the
RED indicator light and the relay are energized. (The relay will “close”
with a loud “clunk” noise when it is energized)
8) Once the trigger cable is tested, disconnect the trigger cable from
the timeclock or controller. Replace the cover on the HPH-4.
9) Now turn ON the main power. The unit is now ready for use.
10) Ensure that the timeclock / controller that will be activating the
HPH-4 is set to turn ON & OFF at the correct times. Reconnecting
the trigger cable will complete the installation.
Important: DO NOT connect 120 volt devices to the receptacles on the
HPH-4. DO NOT connect more than 4000 watts of lighting to the
HPH-4. Only connect (1) ballast per receptacle.
NOTE: Up to (4) ballasts equaling 4000 watts can be controlled by
the HPH-4. Do not exceed the ratings of the unit.

Using the HPH-4
The following describes the most common use for the HPH-4.
Most users who are using multiple HID ballasts will need to make
sure their ballast are wired for use on 240-volt power before
connecting them to the HPH-4.
Unless your ballast have interchangeable power cables, it may be
necessary to open the HID ballast enclosure and physically change
the power connection inside the ballast. It is usually as simple as
disconnecting the wire coming from the ballast transformer marked
(120) , and connecting the wire marked (240) to the ballast’s power
cord.
Because the HPH-4 has “Universal receptacles” that will accept
a variety of different power cables, it is VERY important to double-
check that all of the devices plugged into the HPH-4 are wired
correctly for operation on 240-volt power.
If a 120-volt device is connected to a 240-volt power source, the
device could be permanently damaged or even cause a fire. Be
ABSOLUTELY sure your ballast are wired correctly before
energizing your HPH-4 for the first time.
Once the HPH-4 is connected to the main power source and the
trigger cable is connected to the timeclock or controller that will
activate the HPH-4, the lights connected to the HPH-4 will be
turned ON & OFF automatically by the controlling device.
NOTE: The HPH-4 can also be used to control ballasts wired for 120
volt. You must exactly follow the instructions on page #10 of this
instruction manual. (See *120-Volt Option)
