Automatic Transfer Switch Owner’s Manual 21
Section 5 Maintenance
5.1 — Operate Transfer Switch
Operate the transfer switch at least once each month.
This can be done by performing a NORMAL TEST of the
system. Because the System Test switch only simulates
failure of the UTILITY power source, service is inter-
rupted only during the actual transfer of the load.
5.2 — Clean and Inspect Transfer
Switch
Protect the transfer switch against construction grit, metal
chips, excessive moisture and other harmful dirt at all
times. At least once each year, turn OFF all power sup-
plies to the switch, then brush and vacuum away dust
and dirt that has accumulated inside the enclosure. After
cleaning, inspect the transfer switch carefully. Look for
evidence of arcing, burning, hot spots, charring and other
damage. If any of these are found, have the switch
assembly checked by an authorized service technician.
5.3 — Lubrication
Operating parts inside the transfer mechanism have
been properly lubricated at the time of assembly. Under
normal conditions no additional lubrication should be
required. The service technician should lubricate all rec-
ommended points whenever major transfer mechanism
components are replaced.
IMPORTANT: Use only specified greases to lubricate con-
tactor parts. DO NOT USE ANY SUBSTITUTES.
Use the following lubricants for the:
1. Operating Mechanism (Between movable contact
and busbars).
• Dow Corning (Molykote) BR2 Plus; (Mfg. by Dow
Corning Co., USA)
• Liqui-Moly (Mfg. by DAI TO Co., Ltd., Japan)
2. Main Contacts (Used on the actuator and other
parts of the contactors. Excluding the movable con-
tacts).
• Mobilgrease 28 (Mfg. by Mobil Oil Co.)
• Mobiltemp SHC 32 (Mfg. by Mobil Oil Co.)
• Polo Moly Complex Grease #NLG12 (Mfg. by Polo
Lubricants, USA)
• Rheolube 363 (Mfg. by Nye Lubricants Inc., USA)
5.4 — Main Current Carrying Contacts
At least once annually, have an Authorized Service Tech-
nician check the main current carrying contacts in the
transfer mechanism. They will repair or replace major
components that have been found defective.
5.5 — Batteries
The batteries in the transfer switch controller are of the
nickel metal hydride type. The batteries are recharge-
able. Replace with Panasonic catalog no. HHR75AAA or
equivalent every three (3) years.
