Mounting and Commissioning Instructions

General

This manual contains instructions for unpacking, handling, mounting and wiring of TELEM-GWx products.

Packing

The packing can be stored and reused when needed. The packing itself is not a suitable transport package, but the relay must be further packed as required by the means of transportation to be used. The packing material is recyclable and can be disposed of or recycled according to separate recycling instructions.

Storage

To prevent the possible ingress of dirt, the packing should not be opened until the device is to be used. Long time storage shall be made in dry place.

Checking of the consignment

1. Check the device visually for possible external damage or loose parts inside the device. If the device is found to be damaged,see section “Complaints” 2. Check that the device complies with the order: • ordercode on the side of the device • other possible order-related structural matters. If found incomplete, see section “Complaints”

Complaints Complaints for manufacturing faults are directed in writing to the manufacturer or the authorized dealer, from which the product was acquired. See contact information on section "Reference information". Complaints about transport damage must be sent to the accountable transport or insurance company.

Safety

When mounted into the specific environment the relays express safety in operation. See details in the Technical description of the specific relay.

Electrical safety

National electrical safety regulations must be observed, when work is carried out under live conditions. The TELEM-GWx manufacturer cannot be held responsible for accidents caused by incorrect working or protection practices.

Handling

The correct handling of the relays under all mounting and operating conditions forms the foundation for a correct and safe use of the devices. All separately marked notes and warnings MUST be observed.

Electrostatic discharge

WARNING The TELEM-Gwx devices include components, which are liable to be damaged by electrostatic discharge (ESD). The TELEM-GWx must not be opened without permission from the manufacturer. If done, necessary protective measures against ESD should be taken.

Wiring

General

WARNING The wiring work must be performed according to national standards and possible requirements from the customer. Supply power wires are connected to the screw terminals on the front panel of the device. The terminals are detachable.

Connections

1. Check that the rated values of the TELEM-GWx device comply with those of the intended application. • The auxiliary voltage values can be found from the body of the device. 2. Earth the relay by connecting an earthing wire (minimum cross section 1.5 mm2) to the relays earth terminal. 3. Wire the relay to the rest of the process according to the wiring diagrams of the application. 4. Connect the cable shields of shielded signal cables to the earth terminal of the relay. Checking the wiring Check the secondary wiring by visual inspection and, when needed, by measuring, to eliminate possible incorrect wirings, which may cause malfunction of the relay or associated devices. By visual inspection 1. Perform visual inspection of the wiring. Especially check the wire bunches for adequate slack where needed over hinges. 2. Check the screw terminals for correct tightness. 3. Check, that no wire strands are protruding from the terminals. By measuring 1. Check the connections between the relay and associated devices by using a circuit indicator lamp or buzzer. 2. Check other possible connections by using recognized and reliable working practices.
