computer room or an area of electronic instrumentation. Note that protection
components are in parallel with any loads.
The TVSS Panel should be mounted as close as possible to the circuit
breaker panel to provide maximum surge protection to other branches fed
by other circuit breakers within the circuit breaker panel. It should be noted
that during installation or maintenance of the 57000 TVSS Panel, the circuit
breakers which feed the 57000 must be opened, therefore power to the load
will be momentarily disconnected.
NOTE: The load current is limited to wire size in use, but must not
exceed 100 Amps, maximum continuous current.
In Method 2, Fig. 5, the TVSS Panel is connected through dedicated circuit
breakers of 30 amps. For maximum surge protection, the TVSS Panel
should be mounted as close as possible (no more than 18 inches) from the
circuit breaker panel. Use wire size #10 to #3 AWG, stranded. In a variation of
this connection, the panel circuit breakers can also feed a load by
connecting the TVSS panel to the circuit within an approved connection
enclosure. In this case, the circuit breakers must be rated for this load. The
TVSS panel should be connected to these breakers through a 30-amp rated
(minimum), 3-pole disconnect switch. This facilitates TVSS disconnection
for installation or maintenance without interrupting power to the load.
In Method 3, Fig. 6, for Cat. No. 57000-M3S series, the SPD provides an
integrated disconnect switch. This hook-up provides a method to interrupt
the electrical power to the panel. The series connection should not be used
with this hook-up. When the disconnect switch is turned OFF, power is
removed from the terminal blocks located immediately above the modules.
The disconnect screw terminals accept #14 - #8 AWG wire. Maximum
screw terminal torque is 35 in.-lbs.
6. Conduit attachment: A 2-inch hole in the enclosure is recommended to be
used for In-Out conduit connection.
CAUTION: THE ENCLOSURE MUST BE PROPERLY GROUNDED BY
USE OF #10 AWG MINIMUM SIZE COPPER WIRE ROUTED TO THE "G"
TERMINAL LUG.
7. Attaching the connection leads - TVSS to power lines:
CAUTION: THE FOLLOWING INSTALLATION SHOULD BE
PERFORMED WITH THE POWER OFF! ALWAYS TURN OFF POWER
BEFORE WORKING ON THE TVSS PANEL, SUCH AS WHEN
CHANGING FUSES AND INSERTING OR REMOVING REPLACEABLE
MODULES.
