Installation guide

of the power supply system. The input source for the switch should be reliable and secure, a voltage
adaptor can be used if necessary. The building’s circuit protection system should include in the circuit
a fuse or circuit-breaker of no greater than 240 V, 10 A. It is recommended to use a UPS for more
reliable power supplying. .
Caution
Improper power supply system grounding, extreme fluctuation of the input source, and transients
(or spikes) can result in larger error rate, or even hardware damage!
2.1.1.4 Preventing Electrostatic Discharge Damage
Static electric discharges can cause damage to internal circuits, even the entire switch. Follow
these guidelines for avoiding ESD damage:
 Ensure proper earth grounding of the device;
 Perform regular cleaning to reduce dust;
 Maintain proper temperature and humidity;
 Always wear an ESD wrist strap and antistatic uniform when in contact with circuit boards.
2.1.1.5 Anti-interference
All sources of interference, whether from the device/system itself or the outside environment,
will affect operations in various ways, such as capacitive coupling, inductive coupling,
electromagnetic radiation, common impedance (including the grounding system) and cables/lines
(power cables, signal lines, and output lines). The following should be noted:
 Precautions should be taken to prevent power source interruptions;
 Provide the system with a dedicated grounding, rather than sharing the grounding with the
electronic equipment or lightning protection devices.
 Keep away from high power radio transmitters, radar transmitters, and high frequency strong
circuit devices.
 Provide electromagnetic shielding if necessary.
2.1.1.6 Rack Configuration
The dimensions of the SS3GR50i are designed to be mounted on a standard 19’’ rack, the
dimensions are 440mm x 44mm x 410mm / 440mm x 44mm x 390mm (W x H x D). Please ensure
good ventilation for the rack.
 Every device in the rack will generate heat during operation, therefore vent and fans must be
provided for an enclosed rack, and devices should not be stacked closely.
