Location

You must be properly qualified, trained and authorised to install this unit. Ensure you are qualified to perform each of the operations described.

The Compac DCA is NOT suitable for mounting in a hazardous area.

Please consult the site's zone drawings to find the exact positions of the hazardous areas for each particular site.

For adequately ventilated fuel dispensing sites (not including CNG/NGV), in most cases the following will apply:

 The unit is not designed to be constantly exposed to the elements. A canopy or shelter should be installed to protect it.

 The card reader and PIN pad should face away from the prevailing wind especially in dusty or wet areas.

 In areas experiencing extremes of weather (heat, cold, wind, rain, salt spray etc.) consideration should be given to installing additional shelter.



The DCA location or protection should be such as to minimise the possibility of damage from vehicles, trailers, boats, or the like.

 On heavy vehicle sites, mounting the unit on a raised pad and/or installing bollards to help protect from damage.

 If mounting on a post, the base needs to be attached to a smooth, level surface of sufficient strength to securely hold the retaining bolts or fasteners.

 The DCA should be placed at least 8 metres from any above ground flammable liquid storage or handling facility other than a dispenser.

 The DCA should be placed at least 0.5 metres from any flammable liquid fuel dispensers and 1.5 metres from any LPG dispensers.

 The DCA should be mounted so that the base of the cabinet is at least

1.2 metres above the ground. If mounted on the post supplied by Compac it will be 1.2 metres high.

 Whenever running a cable through the post into the base of the cabinet always ensure that the cable entry into the cabinet uses a vapour tight gland.

 If the DCA post is within 4 metres of a dispenser or within 1 metre of the end of any fuel dispenser hose, then the entire interior of the post may be considered a hazardous area. Any cables running through, or electrical equipment mounted in the post should be suitable for that hazardous area (refer AS/NZS 2381).



Generally the area below the DCA may be a hazardous area and therefore some appropriate signage may be required e.g. no smoking.

 Lighting should be provided during the hours of operation. Lighting should be sufficient to provide safe working conditions that include, but are not limited to, clear visibility of all markings on packages, signs, instruments and other necessary items.

A minimum value of 50 lux is recommended.

These requirements do not apply to any specific site but are merely recommendations that will apply in most cases. The owner/installer must ensure that the installation complies with AS/NZS 3000, AS 1940, and any other applicable regulations.

Guidelines for Mounting the

DCA on a post

Installation Guidelines

If a post is part of the installation:

Make sure you have all the appropriate wiring (power, pump comms, modem, printer etc) led to the location where you are mounting the DCA.

The post assembly should include the following parts:



Galvanised base

 DCA post



Back panel for DCA post

 Flange with 4 studs

 Nuts, washers and spring washers for studs

 Button head cap screws for back plate

Level and securely mount the galvanized post base using appropriate fastenings for the surface it is being mounted on. The mounting plate has 4 x 19 mm holes for fastenings.

Due to the different surfaces that the DCA can be mounted on,

Compac does not supply fastenings for the base plate. Installers should use fastenings suitable for the individual situation.

 Attach the post to the base with the 4 coach bolts provided.

 Feed all wires through the base plate

 Place the DCA cabinet on top of the post and line up the mounting holes in the cabinet to the holes in the base.

 Insert the flange into the post, push the studs through the holes and fasten the cabinet to the post using the 4 washers, spring washers and nuts.

Use only the Compac supplied 4 bolt mounting plate to secure the

DCA to the post.

Feed the wiring into the DCA cabinet using appropriate glands and plug any unused holes in the cabinet.

Mount the cover plate onto the post using the supplied button head cap screws. The cutout goes to the bottom of the post.

No open holes in the base of the DCA cabinet are permitted. Any unused holes in the bottom of the DCA cabinet must be blanked.

Guidelines for Mounting the

DCA on a Wall

If the DCA is to be mounted on a wall, it needs to be attached to a bracket that bolts to and supports the unit from underneath. No holes are to be made in the back of the cabinet unless specifically approved by Compac. All wires into the cabinet must be glanded and all unused holes in the base must be blanked. Refer to diagram on

To help prevent the possibility of unauthorised tampering, it is recommended that tamper resistant fasteners be used and that all wiring outside the cabinet be enclosed.
