MAINTENANCE

5.1

ONSHORE

In general the SIS Bus Bar System is maintenance

free.

Only if the grading distance at open, not covered bus

bar ends (red parts of the bus bars) is heavy coated

with dust, a cleaning with soap water, alcohol or spirit

are recommended. The interval is depending of the

ambient conditions.

Other maintenance work is not necessary for the SIS

Bus Bar System.

If monitoring of the bus bar system is desired,

connections can be tested on different temperature

rise compared to the other phases using an infrared

camera.

If connections are opened due to any reason, please

refer to the SIS Installation Instructions for correct

torques.

Attention: Generally, do not torque Pfisterer Al elast

contact discs and screw connections twice!

Additionally to the under 5.1 described procedure, we

recommend cleaning the pressure release valves at all

outdoor connection sleeves when using an outdoor

system under a salted air atmosphere. This procedure

should be carried out every five years minimum.
