Powermax45 Raw Arc Voltage Kit

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.

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, C-Tick, Kvalitet, EAC) applied to the product in the Hypertherm factory,

and the safety certificates provided by Hypertherm become invalid after modification.

Powermax45 Raw Arc Voltage Kit

Accessing raw arc voltage

Connecting a cable to the Powermax45 power board to bypass the voltage divider and access raw arc voltage must

be done by trained service personnel.

To access raw arc voltage on a Powermax45, you will need the strain relief in kit number 228352 and an 0.75 mm2

(18 AWG), 2 wire, non-shielded cable similar to OLFLEX 190 (601802) in the length needed to go between the power

supply and the CNC or other equipment plus an additional 45.72 cm (18 inches) to connect inside the power supply.

1. On the end of the cable that will be attached to the power supply, strip the outer jacket 11.43 cm (4.5 inches). Cut

6.35 cm (2.5 inches) off of wire 2 so that wire 1 is 11.43 cm (4.5 inches) long and wire 2 is 5.08 cm (2 inches) long.

Then strip 1.27 cm (0.5 inches) of wire insulation off of each wire.

2. Crimp an M4 (#8) insulated ring on the end of wire 1 (negative lead) and an M5 (#10) insulated ring on the end

of wire 2 (positive lead).

3. Remove the 2 screws from the handle on the top of the power supply. Tip the end panels back slightly so that you

can get the edges of the handle out from underneath them. Lift the cover off the power supply. Remove the Mylar®

barrier that protects the power board.

4. Separate the rear panel from the Powermax45 by removing the screw from the bottom and backing the panel away

from the base so that there is enough room to drill out the access point without risk of hitting the interior components.

WARNING!

HIGH VOLTAGE AND CURRENT

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.

Powermax45 Field Service Bulletin 806200 5

Powermax45 Raw Arc Voltage Kit

5. Use a drill with a 15 mm (19/32 inch) drill bit to drill out the access point on the rear panel.

6. Route the cable through the strain relief so that 45.72 cm (18 inches) of insulated wire is on the side of the strain

relief that will go inside the power supply.

7. Thread the 45.72 cm (18 inches) of wire through the hole you drilled in the rear panel and fit the strain relief into the

hole. If necessary, drill out any remaining rough spots so that the strain relief fits snugly.

8. Tighten the strain relief nut on the inside of the rear panel to hold the strain relief in place.

9. Find the grommet closest to the rear panel and at the bottom of the center panel. Route the 2 wires through the

grommet to the power board side of the power supply.

10. Route the wires along the base of the unit and behind the cables connected to the power board.

11 . Remove the work lead connector screw at J21 and the white wire connector screw at J19 (J18 for 400 V CE and

480 V CSA power supplies).

12. Connect wire 1 to J19 (J18 for 400 V CE and 480 V CSA power supplies). Orient the wires such that the ring

connector for wire 1 is closest to the power board, and the connector for the white wire is closest to the head of the

screw. Turn the ring connector for wire 1 upside down so that the slight bend in the ring connector base creates a

little space between the wire and the board. Tighten the screw to 23.0 kg∙cm (20 inch∙pounds).

13. Connect wire 2 to J21. This time, put the connector for the work lead closest to the power board, and put the ring

connector for wire 2 closest to the head of the screw. Torque the screw to 23.0 kg∙cm (20 inch∙pounds).

14. Replace the rear panel and secure it with the screw. Replace the Mylar barrier in front of the power board.

Replace the cover.

15. Tighten the strain relief retention nut onto the strain relief on the outside of the power supply.

16. 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.

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. Overcurrent 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.

Accès à la tension de l’arc brute

Le branchement d’un câble au panneau d’alimentation du Powermax45 afin de contourner le diviseur de tension

et accéder à la tension d’arc brute doit être effectué par un technicien de maintenance qualifié.

Pour accéder à la tension d’arc brute d'un Powermax45, il faut utiliser le serre-câble du kit numéro 228352 et un câble

non blindé à deux fils de calibre 0,75 mm2de type OLFLEX 190 (601802) d’une longueur suffisante pour relier la source

de courant et la CNC ou les autres équipements, en prévoyant une longueur supplémentaire de 45,72 cm pour le

connecter à l’intérieur de la source de courant.

1. Sur l’extrémité du câble devant être branchée à la source de courant, dénuder la gaine extérieure du fil sur une

longueur de 11,43 cm. Raccourcir de 6,35 cm la longueur du fil 2 de sorte à ce que le fil 1 mesure 11,43 cm

et le fil 2 mesure 5,08 cm de long. Dénuder ensuite 1,27 cm d’isolant sur chaque fil.

2. Sertir une cosse ronde isolée M4 (nº 8) à l’extrémité du fil 1 (fil négatif) et une cosse ronde isolée M5 (nº 10)

à l’extrémité du fil 2 (fil positif).

3. Déposer les deux vis de la poignée en haut de la source de courant. Basculer légèrement les panneaux d’extrémité

de façon à en extraire les bords de la poignée d’en dessous. Retirer le couvercle de la source de courant en le levant.
