Raw Arc Voltage Kit

Powermax45 XP Field Service Bulletin 809520 3

Introduction

Purpose

This field service bulletin explains how to install a customer-supplied machine interface cable that

does not use the internal 50:1 voltage divider on the Powermax45 XP.

Notice: Installation of the system at the installed site is subject to the approval of the Local

Inspection Authorities (LIA). Without approval of the LIA, modification of the factory installed

wiring voids the safety test marks (for example, cCSAus, CCC, CE, GOST-TR, UkrSEPRO,

RCM, EAC) applied to the product in the Hypertherm factory, and the safety certificates

provided by Hypertherm become invalid after modification.

Tools and materials needed

Wire strippers

Wire terminal crimper

Assorted Phillips®and TORX®screwdrivers

Electric drill with a 15 mm or 19/32 inch drill bit

0.75 mm2or 18 AWG, 2 wire, non-shielded cable similar to

OLFLEX®190 (manufacturer’s part number 601802)

M3 (#5) insulated ring terminals, quantity 2

WARNING

ELECTRIC SHOCK CAN KILL

Disconnect electrical power before performing any maintenance.

All work requiring removal of the power supply cover must be performed

by a qualified technician.

See the safety information provided with your product for more safety

precautions.

Install the interface cable

Connecting a cable to the power board to bypass the voltage divider board and access raw arc

voltage must be done by trained service personnel.

Remove cover and component barrier

1. Turn OFF the power. Disconnect the power cord and gas supply.

2. Remove the two screws from the power supply handle . Remove the two screws from the

bottom of the front and rear panels. Tilt the tops of the front and rear panels away from the

unit to pull the handle out .

WARNING

SHOCK HAZARD, ENERGY HAZARD, AND FIRE HAZARD

Connecting directly to the plasma circuit for access to raw arc voltage

increases the risk of shock hazard, energy hazard, and fire hazard in the

event of a single fault. The output voltage and the output current of the

circuit are specified on the data plate.

3. Slide the cover off.

4. Remove the two plastic pins that secure the component barrier to the main power board. Slide

the component barrier off.

Prepare the interface cable

1. Use 2 conductor, non-shielded 18 AWG wires to connect to the power supply. Measure the

distance needed to connect from the CNC to the power supply. Add an additional 51.5 cm

(20.25 inches) to make the connection inside the power supply.

2. Cut back the outer jacket 48.3 cm (19 inches) from one end of the cable. Make sure you do not

cut into the insulation on the two 18 AWG wires.

Do not strip the wire ends until after they have been routed through the

power supply.

Install the strain relief

1. Pull the rear panel slightly away from the unit leaving enough space to drill a hole while avoiding

any contact with internal components or wires when drilling.

2. Use a 15 mm (19/32 inch) drill to drill out the interface cable entry point on the panel. Clean the

area of any chips from drilling.

48.3 cm (19 inches)

3. Attach the strain relief (008279) and tighten the inner nut to secure it to the panel. Attach the

outer retention nut but do not tighten.

Connect the interface cable

1. Pass the cable through the strain relief. The outer jacket should slightly protrude through the

back of the strain relief. Make sure the wire length is 48.3 cm (19 inches) inside the power

supply.

2. Tighten the outer retention nut on the strain relief. Make sure the strain relief closes on the

outer jacket of the cable and holds it securely in place.

3. Insert the interface cable wires through the pass-through holes used by the transformer to

reach the other side of the unit.

Different power supply configurations will have the transformer wires

routed differently. Use the pass-through holes that are not utilized by the

transformer.

4. Route the wires to bring the ends to the (-) and (+) threaded inserts on the main circuit board.

5. Strip the insulation 1.27 mm (0.5 inches) from the ends of the wires.

6. Crimp an M3 insulated terminal ring connector on the end of each wire. Make sure there are no

loose wire strands.

7. Connect the positive lead to the (+) threaded insert (J22) on the power supply board. Use one

of the screws included in the kit (075529). Tighten the screw to 23.0 kg∙cm (20 inch·pounds).

Make sure the wire runs downward and the insulated part of the ring terminal is off the board.

8. Connect the negative lead to the (-) threaded insert (J9) on the power supply board. Use one of

the screws included in the kit (075529). Tighten the screw to 23.0 kg∙cm (20 inch-pounds).

Make sure the wire runs downward and the insulated part of the ring terminal is off the board.

9. Make sure to mark on the other end of the cable which wire is positive (+) and which is

negative (-).

10. Replace the component barrier and secure it to the main circuit board with the two plastic pins.

11 . Set the front and rear panels back in place.

12. Make sure the ground clip is connected to the ground wire. The clip should be set in place to

accept the screw from the handle.

13. Slide the cover back on.

14. Tilt the front and rear panels to reattach the handle.

15. Secure the front and rear panel bottom screws.

16. Secure the front and rear panel top screws.

17. Connect the other end of the cable to the equipment according to the manufacturer’s

instructions. Remember to observe polarity.

Notice: The output of the internal voltage divider board is designed to prevent shock, energy

and fire hazards, and is intended to satisfy most codes and standards for external wiring outside

the electrical enclosure. All external wiring practices for an unprotected raw arc voltage

should be reviewed and approved by the Local Inspection Authorities (LIA) at the

time of installation prior to operation and use.

Raw arc voltage wiring terminals and connections should not be exposed to accidental

contact under normal and single fault conditions.

External wiring from an unprotected (that is, no voltage divider used in the power source)

raw arc voltage routed inside conduit between electrical enclosures will normally satisfy all

electrical codes and standards worldwide. Failure to address the hazards associated

with live contact, accessibility and single fault failures to this unprotected output

can result in death or fire.

Raw Arc Voltage Kit

10 809520 Field Service Bulletin Powermax45 XP

A voltage divider board inside the CNC protects only the CNC and does NOT protect the

external interconnecting wiring between the power source and the CNC. Over-current

protection may be required to protect the user and/or machine in fault conditions.

External wiring outside the electrical enclosure should be suitable for the installation and meet

national and local regulations (for example, NFPA 70 NEC, NFPA 79, Canadian Electrical Code,

CSA/CAN E60974-1, IEC 60204-1, BS 7671) or other codes and/or standards applicable to

the installed site where the equipment will be operated.
