GASKET 7M4353 - Caterpillar

The information in this section is to provide the location of the various components in the UPS installation.AC Capacitors and DC Capacitors
DC Capacitors for the 200 kVA, 300 kVA, and 400 kVA Units
For installation, ensure that the torque for the mounting nuts and bus plate connections do not exceed 7 N m (5.2 lb ft). Damage to the capacitors can occur if the required value is exceeded.
For installation, tighten the bus plate bolts first, then tighten the bolts that secure the capacitors to the mounting plate.

AC Capacitors
For installation, ensure that the torque for the mounting nuts and bus plate connections do not exceed 7 N m (5.2 lb ft). Damage to the capacitors can occur if the required value is exceeded.
For installation, tighten the bolts that secure the capacitors to the mounting plate. The bolt torque is 8 N m (5.9 lb ft).200 kVA AC Capacitors
