1.7.4.4 Electrical
Shock
The main supply power presents a risk of electrical shock. This risk is minimized through
isolation and procedures. In addition, several devices will require high voltage power supplies
that may be hazardous. These will be shielded and separately enclosed where possible, with
warning labels attached.
WARNING!: Use extreme caution when working on or around telescope or dome
electrical components.
1.7.4.5 Electrostatic
Discharge
Static electricity may damage some sensitive electronic devices attached to the telescope.
Photo detectors and CCDs are especially vulnerable. Adequate grounding is provided to protect
against this hazard during operation. ESD safe repair procedures should be followed to
minimize the risk of ESD damage during scheduled maintenance.
1.7.5 SAFETY PRECAUTIONS WHILE IN THE TELESCOPE ENCLOSURE
Follow all safety rules when in the enclosure and be alert. Keep a safe distance from the
telescope or enclosure (dome) while they are in use, even if the telescope and dome appear
stationary. If the system is in the middle of tracking, or is being controlled remotely, it can
suddenly and unexpectedly move at any time. Casual visitors to the dome are strongly
discouraged. Avoid wearing any loose fitting clothing items when working around the telescope
enclosure.
1.7.5.1
Emergency Stop Buttons
The telescope is outfitted with Emergency Stop buttons that should only be used for emergency
purposes to stop telescope and or dome movement. Under non-emergency conditions, the
telescope should only be stopped using software commands.
CAUTION: Do not use the Emergency Stop button to turn off power while the
telescope is moving, as damage to telescope or dome drive
mechanisms may occur.
The Emergency Stop button ensures the telescope and dome will not begin to move
unexpectedly. This is particularly important because the telescope and dome can be operated
remotely via an Internet connection.
