10 Maintenance instructions

10.1 What this chapter contains

This chapter contains the maintenance instructions for the active filter. Although your
PQF has been designed for minimum maintenance, the following procedure should be
carefully followed to ensure the longest possible lifetime of your investment.

WARNING: All maintenance work described in this chapter should only be undertaken
by a qualified electrician. The safety instructions presented in

Chapter 2

of this manual

must be strictly adhered to.

WARNING: High AC and DC voltages may be present in the filter panel. Do not touch
any filter parts unless you have ascertained that they do not carry dangerous voltage
levels.

WARNING:

There are AC capacitors & DC capacitors connected inside this filter.

Before performing any maintenance work, please short and ground the three line
terminals. The DC capacitor needs 25 mins to discharge after disconnection. Please
wait for this duration before touching any live parts even after discharging the AC
capacitors to avoid electrical shock

.

WARNING: Under no circumstances close the main contactor manually. Failure to
adhere to this guideline may result in physical injury and/or in filter damage.

10.2 Maintenance intervals

lists the routine maintenance intervals recommended by ABB. Depending on

the operating and ambient conditions, the intervals of

may have to be reduced.

Announced intervals assume that the equipment is operating under ABB approved
operating conditions (Cf.

Chapter 12
