CTF-Xtra Single Phase Advanced SCR
Power Controller Quick Start Manual
0037-75560 (PK538)
This manual is intended to be a quick reference guide for basic installation require-
ments and an overview of the connections, wiring considerations, and general speci-
fications for the CTF-Xtra Advanced SCR Power Controller. For complete installa-
tion, operation, programming and configuration, please refer to the following manuals:
PK535 CTF-Xtra Hardware Instruction Manual; PK534 CTF & CTF-Xtra Controller Pro-
gramming Manual; PK537 C-PWR Configuration Software Manual. The most current
revisions may be found on the Chromalox website: www.chromalox.com.
1. IMPORTANT SAFEGUARDS
ELECTRIC SHOCK HAZARD: Read and understand all instructions before
installing, servicing or operating this controller. Failure to do so could
result in equipment or property damage as well as personal injury and
even death.
HIGH VOLTAGE is used in the operation of this equipment; DEATH ON
CONTACT may result if personnel fail to observe safety precautions.
Learn the areas containing high-voltage connections when installing or
operating this equipment.
Be careful not to contact high-voltage connections when installing or
operating this equipment. Before working inside the equipment, turn
power off and ground all points of high potential before touching them.
ELECTRIC SHOCK HAZARD: Any installation involving control equip-
ment must be performed by a qualified person and must be effectively
grounded in accordance with the National Electrical Code or local gov-
erning electrical code/authority, to eliminate shock hazard.
The owner/installer must provide all necessary safety and protection
devices and follow all current electrical wiring standards and regula-
tions. Failure to do so may compromise the integrity of the controller
and/or cause product failure resulting in a safety risk to operational and
service personnel.
This controller utilizes a heat sink which is designed to cool the unit
during operation. Under no circumstance should air flow around the
controller be compromised in any way. Failure to do so may result in the
overheating of the controller, product failure, product temperatures and
even fire.
During continuous operation, the heat sink can reach very high tem-
peratures, and keeps a high temperature even after the unit is turned
off due to its high thermal inertia.

Installation Wiring Note:
Use the extra rapid fuses as indicated in the CTF-Xtra Hardware Instruction
Manual PK535, according to the wiring schematic examples and controller rating.
Additionally, the applications with solid state units require a safety automatic switch
to disengage the load power line during certain alarm events.
EMC Filter
EMC Filters are required in Phase Angle firing mode. The filter model and current level depend
on the configuration and load used. The power filter MUST be connected as close as possible
to the CTF. You can use a filter connected between the power line and CTF or an LC group
connected between the CTF output and the load.
