4.1CABLE COMPARTMENT NOTE! Removal of cable cover: The cable cover can be supplied with interlocking to earthing switches (additional equipment). When interlocking is fitted, the cable compartment can only be accessed when the earthing switch is in the closed position. 1.
The following types are recommended: Euromold / Elastimold Tyco Electronics nkt-cables Prysmian Südkabel ABB Kabeldon Please see supplier documentation for details. The manufacturer’s installation instructions must be followed. Be sure to lubricate the bushings thoroughly with the silicone supplied. NOTE!
SafeRing / SafePlus with vacuum circuit-breakers are prepared for self-powered OCEF protection relay ABB type REJ 603. Relays with auxiliary voltage SafePlus can be delivered with advanced protection relays: −...
SF leakage from the SF tank pressure, please contact ABB for instructions (NHP 408025). 1. Remove the front cover and unscrew the pressure indicator by unscrewing the hexagon nut as shown on the figure at the right. 2. Screw the adapter to the valve. The tightening torque is max 45 Nm.
2500 meters, gas pressure has to be reduced according to figure on previous page. For installation above 2500 meters, please contact ABB for instructions. Special conditions In accordance with IEC 62271-1, the manufacturer and end- user must agree about special operating conditions which deviate from operation under normal conditions.
OPERATION Before any operation of mechanisms, make sure that front The vacuum circuit-breaker has an integrated lever for the covers are mounted. charging og the springs and push-buttons for operation. All switch-disconnectoer and earthing switches can be Internal mechanical interlocking between the switch- operated with the included operating handle.
5.2.6 VACUUM CIRCUIT-BREAKER - VCB Push button - VCB (OFF) Push button - VCB (ON) Indication - spring charged /( discharged VCB position indicator Counter - closing and opening operations Spring-charging leverr Before operating of the VCB, check that the spring is charged.
5.3 INSTALLATION AND REPLACEMENT OF FUSE LINKS The F-module is equipped with a blown fuse indicator. If this indicator changes colour from white to red, this means that at least 1 fuse-link has blown. This will also automatically trip all three phases of the switch-fuse disconnector.

5. If a fuse-link is already installed but has to be replaced, pull it out. 8. Press the handle and close the fuse canister. 6. Fix the new fuse-link to the fuse cover by means of the contact screw. Note! the striker pin must point towards the fuse cover.
6. ADDITIONAL EQUIPMENT 6.1 MOTOR OPERATION AND AUXILIARY SWITCHES Circuit-breakers, switch-fuse disconnectors and load break switches can be equipped with motor operation. Available control voltages are 24, 48, 60, 110, 230 VDC and 110, 230 VAC. F- and V- modules can also be equipped with closing and opening coils.
6.5 RONIS KEY INTERLOCK To prevent unintended operations, all switches (except switch-disconnector on switch-fuse combination and circuit- breakers) have the possibility to be equipped with Ronis key interlock type EL11AP. 6.6 PADLOCKING DEVICE Ronis key interlock Padlocking device All switches except circuit-breakers are equipped with pad- locking device as standard.
LIFECYCLE CONCEPT FOR TRANSPORT, INSTALLATION, REPAIR , SERVICE AND DISPOSAL AT END OF LIFE ABB is committed to the protection of the environment and It is ABB’s obligation to facilitate end-of-life recycling for our adhere to ISO 14001 standards. The unit contains no subs- products.
