Pole Locations
1. Remove the unit from the packaging
2. Select an elevation and orientation on the pole.
Note: Wires must dress out of the bottom of the unit when installed.
Note: If the rectifier is being mounted overhead (or above 10 ft.) use a hoist and harness to reduce the chance of
serious injury. The recommended harness is approximately a 25 inch loop of 2.5mm diameter Samson
Amsteel Blue Dyneema, or equivalent. This loop is made by taking a 55 inch length and joining the ends
together via an appropriate knot (Figure 3 or water knot are two suggestions) as shown in the view below.
3. Use ¾” inch wide straps to mount the unit to the pole approximately as show in view to the right.
Step 1 - Mount unit to pole
Caution: Use safe lifting practices. Lifting devices are recommended. Steel toed shoes required. The weight of the
unit is 18.0 lbs. and the mounting straps and pole must support 3 times the weight of the unit.
When choosing a location, please keep in mind:
i) The unit must be mounted in “portrait” orientation so that air can flow vertically by natural convection.
ii) Leave at least 3 inches above and below the unit to allow air to feed the fins and exit from the fins.
iii) Mount the unit above the flood line. Note: the unit has weep holes at the bottom to equalize pressure
and drain any water/condensate that may enter.
iv) Orient the wiring entrance toward the ground and provide drip loops to shed any water running down
the jacket.

Step 2 - Ground the unit
There are #10-32 studs on 5/8 centers on the lower back of the unit.
Use this location to provide external grounding as required by code
or network standard. 8 AWG minimum recommended ground wire.

1. Run the DC output cables through the strain relief fittings.
2. If there are more than 2 conductors in the outer jacket, strip the outer jacket to reveal inner jacketed conductors.
3. If there are more than 2 conductors in the jacket, apply 1 inch of heat shrink tubing to the conductor that will be
unused, leaving 1/2 inch of free tubing past the end of the conductor to assure that that conductor will never be
energized..

+ and –48V terminals, toward the left end of the
terminal block. One wire carries +. The other carries
– 48V.
For DC GMT Fuse Version
4. Strip the inner jacket off the two conductors to
expose .4 inches (9mm) of bare conductor to
terminate in circuit breaker and 0.6 inches

Step 5 - Wire the alarms
The unit provides three optional alarm contact closures via three
pluggable terminal block and also provides a ground terminal
block. See Information Table on sheet 18.
1. Run the alarm wires through the appropriate strain relief
fitting.
2. If required, strip the outer jacket to reveal inner jacketed
conductors.
3. Strip the inner jacket to expose 0.3 inches (7 mm) of bare
conductor
4. Connect the pairs of the wires to the pluggable terminal
block. See Information Table on sheet 18.
5. Plug in terminal blocks into the board mounted terminal
block bases
Note: There is no alarm provision for blown fuse or tripped circuit
breaker.
Step 6 - Wire the AC input
Danger: Shock Hazard - Confirm the AC source is NOT ENERGIZED before making AC connections.
Danger: Risque d'électrocution - Vérifiez que la source CA N'EST PAS SOUS TENSION avant d'effectuer les
connexions CA.
When connecting to AC mains, follow all local and national wiring rules.

QUICK START GUIDE
Information - External electrical equipment
This equipment includes an embedded DC output surge protection network to mitigate risk of damage to itself
from external transient events occurring on the DC output conductors. This device is not intended to be used as a
surge suppression device for the externally connected devices being powered by the unit. Connected devices must
provide their own suitable DC input transient suppression as dictated by the equipment’s vendor for the
installation site environment or per company or industry standards (e.g., ITU K series standards).
Information - Lifting the unit
The rectifier assembly is less than 80 lbs. and should have two installers to place the unit into position to the pole
or wall mounting bracket.
Information - External icing
When external icing affects the access to the four hardware screws a plastic or rubber hammer can be used to
break the ICE to remove the securing screws.
Information - For Replacement applications
1. Unlock and open door of unit.
2. Turn mains breaker feeding the unit following Lock-Out Tag-Out procedures.
Warning: Line side of Mains breaker is still energized high voltage.
3. Remove power from source feeding mains breaker in the unit by following local regulatory and National Electric
Code (NEC) practices to deenergize power from the AC meter
4. with a meter, confirm the AC input and DC outputs are all deenergized.

6. Secure all wiring.
7. Remove straps holding the unit in position.
8. Remove the pole mounted unit.
9. Install the replacement unit and secure with the appropriate mounting straps.
