Cleaning Instructions
If dust accumulates on the nGC-30-CRM/-CRMs circuit board use dried compressed air to remove the dust. turn off all power to the nGC-30 panel. Carefully disconnect all cables from a single nGC-30-CRM/-CRMs card, making sure to label cables so that they can be reconnected after board cleaning. Wear an anti-static wrist strap connected to ground in order to avoid component damage. Remove the CRM/CRMs circuit card from the card cage and place on a clean lint-free surface. Use dry compressed air from a can for cleaning circuit boards. (avoid factory compressed air since it may contain enough moisture or oil to cause permanent damage.) Use short quick blasts to remove dust buildup as necessary. after cleaning, replace the CRM/CRMs in the same card cage position and reconnect all cables. Remove only one card at a time for cleaning to avoid any problems during re-installation.
NGC-30-CR Installation Instructions Mounting of Card Rack
Use the mounting template (on page 7) to mount the rack on a panel backplane. there are four holes (0,48 cm dia.) to secure it to the mounting surface using #8 screws. Once the card rack is installed, a earth bonding wire must be connected to the card rack using the ground screw provided. Note: the card rack must be installed on a non-combustible surface.

Power Supply
the power supply connector (tB19) is a dual two pin connector. Either connector allows for power in (pin #1 (+), pin #2 (-) and bussing of power to other nGC-30-CRM modules). Note: Power supply must be sized correctly based on the number of nGC-30-CRM/-CRMs modules.

this connector switches voltage to the contactor coils or solid state relays. the pilot relay will switch the supply voltage (up to 277 Vac) to the contactor coil (using an nGC-30-CRM) or 12 Vdc to the solid state device (using an nGC-30-CRMs).

the Rs-485 connector (tB6) is a dual three pin connector. Either connector allows for Rs-485 input signals (pin #1 (shield), pin #2 (+), pin #3 (-)) and bussing of Rs485 signal to other nGC-30-CRM modules.
RS-485 Communications
Common Alarm
the common alarm terminal block (tB12) provides a form C dry contact, rated at 277 Vac max (3a).
123 123
End of Line (EOL) Jumper
When the Digitrace nGC-30 system is powered on, the common alarm relay coil is energized and pin 2 is connected to pin 1 (common). this is the "no alarm" condition for the CRM/CRMs board. If the alarm occurs, or the CRM/CRMs board loses power, the relay coil is de-energized and pin 1 (common) is disconnected from pin 2 and connected to pin 3 to indicate an alarm condition exits.
123 COM N.C. N.O.
If this device (nGC-30-CRM/-CRMs) is the last device in the Rs-485 network, the J1 jumper needs to be moved from terminals 2 & 3 to terminals 1 & 2.

RTD Inputs - Ordinary Area
3 wire RtDs with shield may be connected to RtD Ch1 thru Ch 5 (tB1 - tB5). the two common wires (usually red, red) are connected to terminals 2 & 3, the source (usually white) to terminal 1 and the braid to terminal 4 (earth ground). Note: RtD's are not required if monitoring current/ground-faults only or if RtD's are connected via MOnI-RMM2s.
Each nGC-30-CRM/-CRMs must have a unique communication address selected. the valid address switch range when using the nGC-UIt is 1-99. sW1 is the ones digit (0-9) and sW2 is the tens digit (0 or 9). Note: When adding an nGC-30-CRM/-CRMs to the system, you must perform a network update at the nGC-UIt.

Optional Voltage Sensor
Cable Preparation
Notes: 1. Cut one end off of a groundfault /line current cable. 2. strip insulation approx. 2,5 cm from cut end. 3. strip the red and black wire insulation approx. 0,5 cm. 4. Connect red and black wire to the two position terminal plug. no need to be concerned about polarity. 5. wtrim brown and orange wires from cut end.
the optional voltage sensor can monitor 80 - 290 Vac. this voltage connects to one of the five line current/ground-fault inputs on the nGC-30-CRM. Note: By using the optional voltage sensor, you lose the ability to monitor the ground-fault and current for that circuit.
Mounting of NGC-30-CTM
Each nGC-30-CtM mounts on a DIn 35 rail. It should be located between the circuit breaker or terminal block and contactor or ssR in the panel.
