Steps prior to power on
Grounding the ICS
The system must be correctly grounded in order to ensure user safety and protect against
lightning and voltage drops, and also to prevent service interruptions.
To ground the M6501L/R IP PBX:
• connect one end of the power cord to the power supply module and the other end to a
grounded mains outlet.
• combine and connect the ground braid (shield) of all the distribution cables to the ground
terminal in the installation's main distribution frame.
Power to the ICS must be switched off when you fit the power cord
Always isolate trunk lines before unplugging the mains power cord.
Never connect trunk lines while the mains power cord is unplugged.
