4-1NOTEBe sure the relay case is hard-wired to earth ground with no smaller than 12 AWGcopper wire attached to the ground terminal on the rear of the relay case. When the relayis configured in a system with other protective devices, it is recommended to use aseparate lead to the ground bus from each relay.SECTION 4INSTALLATIONGENERALWhen not shipped as part of a control or switchgear panel, the relays are shipped in sturdy cartons toprevent damage during transit. Immediately upon receipt of a relay, check the model and style numberagainst the requisition and packing list to see that they agree. Visually inspect the relay for damage that mayhave occurred during shipment. If there is evidence of damage, immediately file a claim with the carrier andnotify the Regional Sales Office, or contact the Sales Representative at Basler Electric, Highland, Illinois.In the event the relay is not to be installed immediately, store the relay in its original shipping carton in amoisture and dust free environment. When the relay is to be placed in service, it is recommended that theoperational test procedure (page 4-5) be performed prior to installation.RELAY OPERATING PRECAUTIONSBefore installation or operation of the relay, note the following precautions:1. The relay is a solid-state device. If a wiring insulation test is required, remove the connection plugsand withdraw the cradle from its case.2. When the connection plugs are removed, the relay is disconnected from the operating circuit andwill not provide system protection. Always be sure that external operating (monitored) conditionsare stable before removing a relay for inspection, test, or service.3. Be sure the relay case is hard wired to earth ground using the ground terminal on the rear of theunit. It is recommended to use a separate ground lead to the ground bus for each relay.DIELECTRIC TESTIn accordance with IEC 255-5 and ANSI/IEEE C37.90-1989, one-minute dielectric (high potential) tests upto 1500 Vac (45-65 Hz) may be performed. Note that this device employs decoupling capacitors to groundfrom terminals 1 through 9, and 11 through 20. At 1500 Vac, a leakage current of approximately 5milliamperes per terminal is to be expected./1706+0)Because the relay is of solid state design, it does not have to be mounted vertically. Any convenientmounting angle may be chosen. Relay outline dimensions and panel drilling diagrams are supplied at theend of this section.%100'%6+105Incorrect wiring may result in damage to the relay. Be sure to check model and style number against theoptions listed in the Style Number Identification Chart before connecting and energizing a particular relay.
