6. Power and data connection
This section describes how to connect the Inground 200 to AC power. For Inground 200 6 Color and
Full Spectrum CMY models, it also describes how to connect control data cables.
AC power supply
Warning!
For protection from potentially lethal electric shock:
• The fixture must be grounded (earthed).
• The AC mains supply must be fitted with a fuse or circuit breaker, ground-fault
protection, and a means to isolate the fixture from the mains during service or
when not in use.
• Cables and fixtures must be isolated from AC power, and steps taken to prevent
reconnection, before carrying out any work on them.
• Voltage and frequency settings must be checked before applying power.
• The fixture must not be connected to an electrical dimmer system: doing so can
damage the electronics.
Power supply settings
The Inground 200 is configured at the factory for one of the two power supply settings listed in Table
1 below. The factory power supply settings are printed on the product serial number labels outside
and inside the housing. If your local AC voltage or frequency differ from the settings for your model,
the fixture’s power supply must be rewired by an authorized Martin Architectural service dealer.
Cable glands
Cable glands must be replaced if the power or data cable is replaced with a cable of a different
diameter. Replacement glands, available from electrical suppliers, must have the following
characteristics.
Temperature range: ........................................................ -20° to 70° C or better
Ingress protection rating: ................................................................. IP 67 or 68
Power cable gland thread size: ......................................................... M25 x 1.5
Data cable gland thread size: ............................................................. M16 x 1.5
Minimum entry thread length: .................................................................. 8 mm
Connecting power supply cables
The Inground 200 is supplied with 2 stainless steel M25 x 1.5mm cable glands, water resistant to
IP68, for AC power cable entry. The glands accept from 13 to 17mm diameter cable.
