Installing the PXM-1&2
In order to ensure a safe and proper installation of the PXMs,
follow the steps below.
1) Select the location for the device to be used. Keep the PXM away
from water. Determine where the main power supply will be
connected to the PXM and ensure the main power cable will reach.
2) Secure the wall mount bracket using the screws included.
3) The PXM can then be mounted to the wall bracket using the
supplied thumb screws.
4) DO NOT turn connect the power cable yet.
5) Connect the 120 volt trigger cable to the time-clock or controller
that will be turning the PXM ON & OFF. Either of the (2) low-volt
power jacks on the left side can be used. Up to (2) PXMs can be
connected to a single low-volt trigger power supply.
6) Energize
(over-ride)
the time-clock or controller and verify the
RED indicator light and the relay are energized on the PXM.
7) Once the trigger cable is tested, disconnect the low volt trigger
cable from the PXM.
8) Connect the device(s) that will be controlled by the PXM to the
(2) power receptacles on the bottom of the PXM.
9) Verify that the circuit breaker on the bottom of the unit is in the
OFF position.
10) The main power cable can now be connected to the power
source. Select a dedicated 15-20 amp @ 120 volt circuit to draw
power from and plug the power cable into the wall outlet.
11) Now turn ON the circuit breaker.
12) Ensure that the time-clock / controller that will be activating the
PXM is set to turn ON & OFF at the correct times. Reconnecting the
low-volt trigger cable will complete the installation.
Important: Make sure devices connected to the receptacles on the PXM
are the correct voltages. DO NOT connect devices more than 15-amps.
Large load devices example
The most common use for the PXM-1&2 is to be able to
control larger equipment and additional lights. The PXMs have
high-power relays inside that turn the devices connected to it ON
and OFF. A trigger power supply activates the relays. The trigger
power supply is connected to any 120 volt controller or timer.
When the controller or timer activates the trigger power supply,
the PXM is “remotely” controlled by the controller or the timer.
WARNING:
Verify the equipment you are connecting to the PXM
does not exceed the ratings of the PXM. (Refer to specifications)
