4Installation and commissioning
DANGERDANGER!
Risk of explosion due to unsafe connections.
The use of industrial (non-explosion protected) rated components such as(digital) bus terminators or T-parts provide insufficient protection.
▶ Only use correct Ex-certified terminal or junction boxes for cable
extensions or cable splits.
▶ Only use the supplied mating cables in the safe area.
If the supplied cables need to be extended, the area in which the connection is mademust be taken into account.
▶ Only use suitable Ex-certified terminal- or junction boxes [1].
- or ▶ Only extend supplied mating cables in the safe area [2].

Risk of explosion due to spark discharges!
Disconnecting the product without turning off the electrical power first, maycause a spark. This may lead to an explosion.
▶ Remove electrical power from the product before connecting or
disconnecting electrically.

1

WARNING
Risk of explosion due to improper installation!

Safe area

Unprotected electrical connections may lead to unforeseeable issues, which
may lead to personal injury.
▶ Install the supplied IP65 caps (» par. 4.4).
CAUTION

2

Risk of personal injury due to pressure release!
Pressurized fluids may cause personal injury if released suddenly.
▶ Release the pressure from the fluidic lines slowly.

4.1

Product labeling▶ Read the serial number label on the product and check applicability of:- Flow/pressure rate
- Fluid to be metered and compatibility- Up- and downstream pressures- Input/output signal▶ Check from the red-colored sticker on the product, that the test pressure is inagreement with the required safety factor for the application.

4.2

Transport bolts (model M15 only)

The model M15 is fitted with transport bolts, which need to be removed before
energizing the product.
▶ Remove the bolts according to the instructions supplied with the product.

4.3

Preparations and process connection▶ Refer to the standard manual supplied with the product for complete installation
instructions and commissioning (» par. 2.1, page 3).
▶ Release the pressure from the fluidic lines.
▶ Clear the fluidic lines of hazardous gas or liquid.
▶ Install the meter/controller in the line.
▶ Tighten the fluidic (gas/liquid) fittings according to the instructions of the
supplier of the fittings.

4.5

Impact protection of electrical connections

The product is supplied with (impact) protection cover protecting electricalconnections. In case of alternative means of impact protection, see '4.6 Alternative
impact protection or cabling' on page 9.
To mount the supplied protection cover:▶ Identify applicable model and cover (» Fig. 2 ... Fig. 10).
▶ Place the cover up to the fixed stop [A].
▶ Insert the bolts [2].
▶ Tighten the bolts evenly with indicated torque [3].

Electrical connections
When making electrical connections, it is important to follow the
instructions of the connector manufacturer. This to ensure and maintainingress protection and a secure mechanical connection.

▶ De-energize product and cables.
▶ Use the supplied mating cables.
▶ Make sure, both the chassis socket and the cable connectors, are clean and dry.
▶ Insert the cable connector in the designated chassis socket.
▶ Tighten the connector-ring hand-tight.
▶ Use supplied IP65 caps to close unused electrical connections.
▶ Before energizing: check all electric connections according to the supplied
hook-up diagram.
