Location Requirements

Do not substitute or modify system components as this may impair intrinsic safety. For installation, mainte- nance or operation instructions, read instruction manu- als. Do not install equipment approved only for non-hazardous location in a hazardous area. See the identification label (FIG. 1) on the EasyKey or fluid sta- tion for the intrinsic safety rating for your model.

•Mount EasyKey and Fluid Station within 50 ft (15.2 m) of each other, using 15U533 cable.

NOTE: An optional 15V213 100 ft (30.5 m) cable is also available.

•EasyKey: Install in the non-hazardous area at a convenient location for the operator to view and operate.

•Fluid Station: Install according to requirements for Intrinsically Safe Installation (FIG. 3) and at a conve- nient location to connect to paint and solvent sup- plies.

NOTE: For an Intrinsically Safe Installation, the Fluid Station may be located inside or outside the hazardous location. Install according to appropriate electrical codes.

Intrinsically Safe Installation Requirements

See FIG. 3 on page 13.

1.The non-intrinsically safe terminals (power rail) must not be connected to any device which uses or gen- erates more than 250 Vrms or dc unless it has been determined that the voltage has been adequately isolated.

2.The installation must meet the requirements of the National Electric Code, Canadian Electrical Code Part I, NFPA 70, Article 504 Resp., Article 505 and ANSI/ISA 12.06.01.

3.Multiple earthing of components is allowed only if high integrity equipotential system is realized between the points of bonding.

4.Do not operate system with safety barrier cover removed.

5.For ATEX, install per EN 60079-14 and applicable local and national codes.

6.Install Coriolis flow meters as explosion proof (USA, Canada)/flameproof Ex d (ATEX) with passive intrin- sically safe connections per the manufacturer’s installation instructions and applicable codes.

7.Terminals 24 and 25 of optional Endress+Hauser Coriolis flow meters installed using intrinsically safe wiring methods. For the United States and Canada, install all other wiring for Coriolis flow meters using explosion proof wiring methods for Division I. For ATEX installations, install all other wiring for Coriolis flow meters using Flameproof, Ex d, wiring methods for Zone 1. Observe manufacturer’s instructions for installation and use.

8.For ATEX installations, interconnecting cabling specified is Type A cable in accordance with EN 60079-14.

Optional Cables

Optional CAN cables and fiber optic cables are available from Graco. See the ProControl 1KS Repair-Parts man- ual for available part numbers and lengths.
