4-1.
Pre-Installation Considerations.
To ensure reliable and safe operation of the system, the following items must be considered before
installing the receiver unit.
WARNING
THE RECEIVER UNIT OR RELAYS ARE NOT RATED AS EXPLOSION PROOF. THE RECEIVER
UNIT MUST NOT BE INSTALLED IN EXPLOSIVE ENVIRONMENTS UNLESS APPROPRIATE
SECONDARY ENCLOSURE MEASURES ARE TAKEN. FAILURE TO FOLLOW THIS WARNING
COULD RESULT IN SERIOUS INJURY OR DEATH AND DAMAGE TO EQUIPMENT.
4-2.
Receiver Unit Mounting Location Considerations.
Ensure the mounting location is as far as possible from exposed trolley wires and sources of
electromagnetic or radiated noise
The receiver cabinet is approximately 8" (20 cm) wide by 12" (30 cm) high. A depth of at least 6" (15 cm)
must be provided to allow the cabinet door to open.
The mounting surface must be smooth and continuous. Mounting the cabinet on uneven surfaces could
cause warpage or stress internal components.
The receiver unit may be mounted in any position. Greatest radio control range is obtained when the
receiver unit is mounted with the antenna at the top.
If possible, avoid installing receiver unit to a surface where high vibration or shock is present. If this cannot
be avoided, use appropriate shock mounts.
4-3.
Antenna Mounting Considerations.
The antenna is internal and requires no additional mounting. The antenna is at the top of the receiver
cabinet and should not be placed near large metal objects that could be close to or cover the top of the box.
Allow at least six inches above the top of the box for clearance.
4-4.
Line Input Considerations.
WARNING
THE UNIT MUST BE WIRED TO THE CORRECT VOLTAGE, AND BE CONNECTED TO THE
CORRECT TERMINAL AS REQUIRED BY THE ACTUAL LINE VOLTAGE. FAILURE FOLLOW
THIS WARNING COULD RESULT IN SERIOUS INJURY OR DEATH AND DAMAGE TO
EQUIPMENT
.
The receiver unit has direct connect provisions for operation from 120 (nominal), 50-60 Hz power.
For applications where line voltage deviation exceeds 20% of nominal values if line voltage is not between
95-130 VAC or 190-260 VAC or if 440 VAC power is used, a step up or step down transformer must be
used.
