Installation

Installation

To avoid electric shock, turn off power at the main circuit breaker before opening the enclosure.

All electrical wiring must be done by a qualified electrician and comply with all local codes and regulations.

Do not substitute or modify system components as this may impair intrinsic safety.

Do not install equipment approved only for non-hazardous location in a hazardous location. See the identification label for the intrinsic safety rating for your model.

This equipment stays pressurized until pressure is manually relieved. To help prevent serious injury from pressurized fluid, such as skin injection, splashing fluid and moving parts, follow the Pressure Relief Procedure in the PD2K Operation Manual before installing the kit.

Mounting the Control Modules

1.See Dimensions, page 71.

2.Ensure that the wall and mounting hardware are strong enough to support the weight of the equipment, fluid, hoses, and stress cause during operation.

3.Using the equipment as a template, mark the mounting holes on the wall at a convenient height for the operator and so the equipment is easily accessible for maintenance.

NOTE: The smaller color change control modules must be mounted in the Non-IS area. The larger remote color change module may be mounted in the IS area.

4.Drill mounting holes in the wall. Install anchors as needed.

5.Bolt the equipment securely.

Air Supply

Connect a clean and dry air supply to the air inlet fitting (317) of each color change control module in the non-hazardous area and each remote module in the hazardous area. The fitting is for 1/4 in. (6 mm) OD tubing. Use a 5 micron filter. Regulate the air pressure to 85–100 psi (0.6–0.7 MPa, 6.0–7.0 bar).

Grounding

This equipment must be grounded to reduce the risk of static sparking and electric shock. Electric or static sparking can cause fumes to ignite or explode. Improper grounding can cause electric shock. Grounding provides an escape wire for the electric current.

Connect a ground wire from each color change module in the non-hazardous area to a true earth ground.

Intrinsically safe remote color change modules located in the hazardous area must be connected to a true earth ground in the hazardous area.
